Криптовалюта — цифровой актив, учёт которого децентрализован. Функционирование данных систем происходит при помощи распределённой компьютерной сети. При этом информация о транзакциях может не шифроваться и быть доступна в открытом виде. Для гарантирования неизменности цепочки блоков базы транзакций используется криптография. Термин закрепился вследствие статьи o Bitcoin «Crypto currency» (Криптографическая валюта), опубликованной в 2011 году в журнале Forbes. Сам же автор Bitcoin, как и многие другие, использовал термин «электронная наличность» (Electronic cash). Способ эмиссии криптовалют может представлять собой майнинг, форжинг или IPO.

A cryptocurrency, crypto-currency, or crypto is a digital currency designed to work as a medium of exchange through a computer network that is not reliant on any central authority, such as a government or bank, to uphold or maintain it.[2] It is a decentralized system for verifying that the parties to a transaction have the money they claim to have, eliminating the need for traditional intermediaries, such as banks, when funds are being transferred between two entities.[3]
Individual coin ownership records are stored in a digital ledger, which is a computerized database using strong cryptography to secure transaction records, control the creation of additional coins, and verify the transfer of coin ownership.[4][5][6] Despite their name, cryptocurrencies are not considered to be currencies in the traditional sense, and while varying treatments have been applied to them, including classification as commodities, securities, and currencies, cryptocurrencies are generally viewed as a distinct asset class in practice.[7][8][9] Some crypto schemes use validators to maintain the cryptocurrency. In a proof-of-stake model, owners put up their tokens as collateral. In return, they get authority over the token in proportion to the amount they stake. Generally, these token stakers get additional ownership in the token over time via network fees, newly minted tokens, or other such reward mechanisms.[10]
Cryptocurrency does not exist in physical form (like paper money) and is typically not issued by a central authority. Cryptocurrencies typically use decentralized control as opposed to a central bank digital currency (CBDC).[11] When a cryptocurrency is minted, or created prior to issuance, or issued by a single issuer, it is generally considered centralized. When implemented with decentralized control, each cryptocurrency works through distributed ledger technology, typically a blockchain, that serves as a public financial transaction database.[12] Traditional asset classes like currencies, commodities, and stocks, as well as macroeconomic factors, have modest exposures to cryptocurrency returns.[13]
The first decentralized cryptocurrency was Bitcoin, which was first released as open-source software in 2009. As of March 2022, there were more than 9,000 other cryptocurrencies in the marketplace, of which more than 70 had a market capitalization exceeding $1 billion.[14]
History
In 1983, American cryptographer David Chaum conceived of a type of cryptographic electronic money called ecash.[15][16] Later, in 1995, he implemented it through Digicash,[17] an early form of cryptographic electronic payments. Digicash required user software in order to withdraw notes from a bank and designate specific encrypted keys before it can be sent to a recipient. This allowed the digital currency to be untraceable by a third party.
In 1996, the National Security Agency published a paper entitled How to Make a Mint: the Cryptography of Anonymous Electronic Cash, describing a cryptocurrency system. The paper was first published in an MIT mailing list[18] and later in 1997 in The American Law Review.[19]
In the 1997 book The Sovereign Individual, the authors, William Rees-Mogg and James Dale Davidson, predicted that the currency used in the information age would be using «mathematical algorithms that have no physical existence»,[20] which has led some in the cryptocurrency community to call the book’s claim a «prophecy».[21]
In 1998, Wei Dai described «b-money», an anonymous, distributed electronic cash system.[22] Shortly thereafter, Nick Szabo described bit gold.[23] Like Bitcoin and other cryptocurrencies that would follow it, bit gold (not to be confused with the later gold-based exchange BitGold) was described as an electronic currency system which required users to complete a proof of work function with solutions being cryptographically put together and published.
In January 2009, Bitcoin was created by pseudonymous developer Satoshi Nakamoto. It used SHA-256, a cryptographic hash function, in its proof-of-work scheme.[24][25] In April 2011, Namecoin was created as an attempt at forming a decentralized DNS. In October 2011, Litecoin was released which used scrypt as its hash function instead of SHA-256. Peercoin, created in August 2012, used a hybrid of proof-of-work and proof-of-stake.[26]
On 6 August 2014, the UK announced its Treasury had commissioned a study of cryptocurrencies, and what role, if any, they could play in the UK economy. The study was also to report on whether regulation should be considered.[27] Its final report was published in 2018,[28] and it issued a consultation on cryptoassets and stablecoins in January 2021.[29]
In June 2021, El Salvador became the first country to accept Bitcoin as legal tender, after the Legislative Assembly had voted 62–22 to pass a bill submitted by President Nayib Bukele classifying the cryptocurrency as such.[30]
In August 2021, Cuba followed with Resolution 215 to recognize and regulate cryptocurrencies such as Bitcoin.[31]
In September 2021, the government of China, the single largest market for cryptocurrency, declared all cryptocurrency transactions illegal. This completed a crackdown on cryptocurrency that had previously banned the operation of intermediaries and miners within China.[32]
On 15 September 2022, the world second largest cryptocurrency at that time, Ethereum transitioned its consensus mechanism from proof-of-work (PoW) to proof-of-stake (PoS) in an upgrade process known as «the Merge». According to the Ethereum Founder, the upgrade can cut Ethereum’s energy use by 99.9% and carbon-dioxide emissions by 99.9%.[33]
On 11 November 2022, FTX Trading Ltd., a cryptocurrency exchange, which also operated a crypto hedge fund, and had been valued at $18 billion,[34] filed for bankruptcy.[35] The financial impact of the collapse extended beyond the immediate FTX customer base, as reported,[36] while, at a Reuters conference, financial industry executives said that «regulators must step in to protect crypto investors.»[37] Technology analyst Avivah Litan commented on the cryptocurrency ecosystem that «everything…needs to improve dramatically in terms of user experience, controls, safety, customer service.»[38]
Formal definition
According to Jan Lansky, a cryptocurrency is a system that meets six conditions:[39]
- The system does not require a central authority; its state is maintained through distributed consensus.
- The system keeps an overview of cryptocurrency units and their ownership.
- The system defines whether new cryptocurrency units can be created. If new cryptocurrency units can be created, the system defines the circumstances of their origin and how to determine the ownership of these new units.
- Ownership of cryptocurrency units can be proved exclusively cryptographically.
- The system allows transactions to be performed in which ownership of the cryptographic units is changed. A transaction statement can only be issued by an entity proving the current ownership of these units.
- If two different instructions for changing the ownership of the same cryptographic units are simultaneously entered, the system performs at most one of them.
In March 2018, the word cryptocurrency was added to the Merriam-Webster Dictionary.[40]
Altcoins
Tokens, cryptocurrencies, and other digital assets other than Bitcoin are collectively known as alternative cryptocurrencies,[41][42][43] typically shortened to «altcoins» or «alt coins»,[44][45] or disparagingly «shitcoins».[46] Paul Vigna of The Wall Street Journal also described altcoins as «alternative versions of Bitcoin»[47] given its role as the model protocol for altcoin designers.
The logo of Ethereum, the second largest cryptocurrency
Altcoins often have underlying differences when compared to Bitcoin. For example, Litecoin aims to process a block every 2.5 minutes, rather than Bitcoin’s 10 minutes, which allows Litecoin to confirm transactions faster than Bitcoin.[48] Another example is Ethereum, which has smart contract functionality that allows decentralized applications to be run on its blockchain.[49] Ethereum was the most used blockchain in 2020, according to Bloomberg News.[50] In 2016, it had the largest «following» of any altcoin, according to the New York Times.[51]
Significant rallies across altcoin markets are often referred to as an «altseason».[52][53]
Stablecoins
Stablecoins are cryptocurrencies designed to maintain a stable level of purchasing power.[54] Notably, these designs are not foolproof, as a number of stablecoins have crashed or lost their peg. For example, on 11 May 2022, Terra’s stablecoin UST fell from $1 to 26 cents.[55][56] The subsequent failure of Terraform Labs resulted in the loss of nearly $40B invested in the Terra and Luna bitcoins.[57] In September 2022, South Korean prosecutors requested the issuance of an Interpol Red Notice against the company’s founder, Do Kwon.[58]
Architecture
Cryptocurrency is produced by an entire cryptocurrency system collectively, at a rate which is defined when the system is created and which is publicly stated. In centralized banking and economic systems such as the US Federal Reserve System, corporate boards or governments control the supply of currency.[citation needed] In the case of cryptocurrency, companies or governments cannot produce new units, and have not so far provided backing for other firms, banks or corporate entities which hold asset value measured in it. The underlying technical system upon which cryptocurrencies are based was created by Satoshi Nakamoto.[59]
Within a proof-of-work system such as Bitcoin, the safety, integrity and balance of ledgers is maintained by a community of mutually distrustful parties referred to as miners. Miners use their computers to help validate and timestamp transactions, adding them to the ledger in accordance with a particular timestamping scheme.[24] In a proof-of-stake blockchain, transactions are validated by holders of the associated cryptocurrency, sometimes grouped together in stake pools.
Most cryptocurrencies are designed to gradually decrease the production of that currency, placing a cap on the total amount of that currency that will ever be in circulation.[60] Compared with ordinary currencies held by financial institutions or kept as cash on hand, cryptocurrencies can be more difficult for seizure by law enforcement.[4]
Blockchain
The validity of each cryptocurrency’s coins is provided by a blockchain. A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography.[59][61] Each block typically contains a hash pointer as a link to a previous block,[61] a timestamp and transaction data.[62] By design, blockchains are inherently resistant to modification of the data. It is «an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way».[63] For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority.
Blockchains are secure by design and are an example of a distributed computing system with high Byzantine fault tolerance. Decentralized consensus has therefore been achieved with a blockchain.[64]
Nodes
A node is a computer that connects to a cryptocurrency network. The node supports the cryptocurrency’s network through either relaying transactions, validation, or hosting a copy of the blockchain. In terms of relaying transactions, each network computer (node) has a copy of the blockchain of the cryptocurrency it supports. When a transaction is made, the node creating the transaction broadcasts details of the transaction using encryption to other nodes throughout the node network so that the transaction (and every other transaction) is known.
Node owners are either volunteers, those hosted by the organization or body responsible for developing the cryptocurrency blockchain network technology, or those who are enticed to host a node to receive rewards from hosting the node network.[65]
Timestamping
Cryptocurrencies use various timestamping schemes to «prove» the validity of transactions added to the blockchain ledger without the need for a trusted third party.
The first timestamping scheme invented was the proof-of-work scheme. The most widely used proof-of-work schemes are based on SHA-256 and scrypt.[26]
Some other hashing algorithms that are used for proof-of-work include CryptoNight, Blake, SHA-3, and X11.
Another method is called the proof-of-stake scheme. Proof-of-stake is a method of securing a cryptocurrency network and achieving distributed consensus through requesting users to show ownership of a certain amount of currency. It is different from proof-of-work systems that run difficult hashing algorithms to validate electronic transactions. The scheme is largely dependent on the coin, and there’s currently no standard form of it. Some cryptocurrencies use a combined proof-of-work and proof-of-stake scheme.[26]
Mining
On a blockchain, mining is the validation of transactions. For this effort, successful miners obtain new cryptocurrency as a reward. The reward decreases transaction fees by creating a complementary incentive to contribute to the processing power of the network. The rate of generating hashes, which validate any transaction, has been increased by the use of specialized machines such as FPGAs and ASICs running complex hashing algorithms like SHA-256 and scrypt.[66] This arms race for cheaper-yet-efficient machines has existed since Bitcoin was introduced in 2009.[66]
With more people venturing into the world of virtual currency, generating hashes for validation has become more complex over time, forcing miners to invest increasingly large sums of money to improve computing performance. Consequently, the reward for finding a hash has diminished and often does not justify the investment in equipment and cooling facilities (to mitigate the heat the equipment produces), and the electricity required to run them.[67] Popular regions for mining include those with inexpensive electricity, a cold climate, and jurisdictions with clear and conducive regulations. By July 2019, Bitcoin’s electricity consumption was estimated to be approximately 7 gigawatts, around 0.2% of the global total, or equivalent to the energy consumed nationally by Switzerland.[68]
Some miners pool resources, sharing their processing power over a network to split the reward equally, according to the amount of work they contributed to the probability of finding a block. A «share» is awarded to members of the mining pool who present a valid partial proof-of-work.
As of February 2018, the Chinese Government has halted trading of virtual currency, banned initial coin offerings and shut down mining. Many Chinese miners have since relocated to Canada[69] and Texas.[70] One company is operating data centers for mining operations at Canadian oil and gas field sites, due to low gas prices.[71] In June 2018, Hydro Quebec proposed to the provincial government to allocate 500 megawatts of power to crypto companies for mining.[72] According to a February 2018 report from Fortune, Iceland has become a haven for cryptocurrency miners in part because of its cheap electricity.[73]
In March 2018, the city of Plattsburgh, New York put an 18-month moratorium on all cryptocurrency mining in an effort to preserve natural resources and the «character and direction» of the city.[74] In 2021, Kazakhstan became the second-biggest crypto-currency mining country, producing 18.1% of the global hash rate. The country built a compound containing 50,000 computers near Ekibastuz.[75]
GPU price rise
An increase in cryptocurrency mining increased the demand for graphics cards (GPU) in 2017.[76] The computing power of GPUs makes them well-suited to generating hashes. Popular favorites of cryptocurrency miners such as Nvidia’s GTX 1060 and GTX 1070 graphics cards, as well as AMD’s RX 570 and RX 580 GPUs, doubled or tripled in price – or were out of stock.[77] A GTX 1070 Ti which was released at a price of $450 sold for as much as $1,100. Another popular card, the GTX 1060 (6 GB model) was released at an MSRP of $250, and sold for almost $500. RX 570 and RX 580 cards from AMD were out of stock for almost a year. Miners regularly buy up the entire stock of new GPU’s as soon as they are available.[78]
Nvidia has asked retailers to do what they can when it comes to selling GPUs to gamers instead of miners. Boris Böhles, PR manager for Nvidia in the German region, said: «Gamers come first for Nvidia.»[79]
Wallets
An example paper printable Bitcoin wallet consisting of one Bitcoin address for receiving and the corresponding private key for spending
A cryptocurrency wallet is a means of storing the public and private «keys» (address) or seed which can be used to receive or spend the cryptocurrency.[80] With the private key, it is possible to write in the public ledger, effectively spending the associated cryptocurrency. With the public key, it is possible for others to send currency to the wallet.
There exist multiple methods of storing keys or seed in a wallet. These methods range from using paper wallets (which are public, private or seed keys written on paper), to using hardware wallets (which are hardware to store your wallet information), to a digital wallet (which is a computer with a software hosting your wallet information), to hosting your wallet using an exchange where cryptocurrency is traded, or by storing your wallet information on a digital medium such as plaintext.[81]
Anonymity
Bitcoin is pseudonymous, rather than anonymous; the cryptocurrency in a wallet is not tied to a person, but rather to one or more specific keys (or «addresses»).[82] Thereby, Bitcoin owners are not immediately identifiable, but all transactions are publicly available in the blockchain.[83] Still, cryptocurrency exchanges are often required by law to collect the personal information of their users.[84]
Some cryptocurrencies, such as Monero, Zerocoin, Zerocash, and CryptoNote, implement additional measures to increase privacy, such as by using zero-knowledge proofs.[85][86]
Economics
Cryptocurrencies are used primarily outside banking and governmental institutions and are exchanged over the Internet.
Block rewards
Proof-of-work cryptocurrencies, such as Bitcoin, offer block rewards incentives for miners. There has been an implicit belief that whether miners are paid by block rewards or transaction fees does not affect the security of the blockchain, but a study suggests that this may not be the case under certain circumstances.[87]
The rewards paid to miners increase the supply of the cryptocurrency. By making sure that verifying transactions is a costly business, the integrity of the network can be preserved as long as benevolent nodes control a majority of computing power. The verification algorithm requires a lot of processing power, and thus electricity in order to make verification costly enough to accurately validate public blockchain. Not only do miners have to factor in the costs associated with expensive equipment necessary to stand a chance of solving a hash problem, they further must consider the significant amount of electrical power in search of the solution. Generally, the block rewards outweigh electricity and equipment costs, but this may not always be the case.[88]
The current value, not the long-term value, of the cryptocurrency supports the reward scheme to incentivize miners to engage in costly mining activities.[89] Some sources[weasel words] claim that the current Bitcoin design is very inefficient, generating a welfare loss of 1.4% relative to an efficient cash system. The main source for this inefficiency is the large mining cost, which is estimated to be US$360 million per year. This translates into users being willing to accept a cash system with an inflation rate of 230% before being better off using Bitcoin as a means of payment. However, the efficiency of the Bitcoin system can be significantly improved by optimizing the rate of coin creation and minimizing transaction fees. Another potential improvement is to eliminate inefficient mining activities by changing the consensus protocol altogether.[90]
Transaction fees
Transaction fees for cryptocurrency depend mainly on the supply of network capacity at the time, versus the demand from the currency holder for a faster transaction.[citation needed] The currency holder can choose a specific transaction fee, while network entities process transactions in order of highest offered fee to lowest.[citation needed] Cryptocurrency exchanges can simplify the process for currency holders by offering priority alternatives and thereby determine which fee will likely cause the transaction to be processed in the requested time.[citation needed]
For Ethereum, transaction fees differ by computational complexity, bandwidth use, and storage needs, while Bitcoin transaction fees differ by transaction size and whether the transaction uses SegWit. In September 2018[needs update], the median transaction fee for Ether corresponded to $0.017,[91] while for Bitcoin it corresponded to $0.55.[92]
Some cryptocurrencies have no transaction fees, and instead rely on client-side proof-of-work as the transaction prioritization and anti-spam mechanism.[93][94][95]
Exchanges
Cryptocurrency exchanges allow customers to trade cryptocurrencies[96] for other assets, such as conventional fiat money, or to trade between different digital currencies.
Crypto marketplaces do not guarantee that an investor is completing a purchase or trade at the optimal price. As a result, many investors take advantage of this by using arbitrage to find the difference in price across several markets.[97]
Atomic swaps
Atomic swaps are a mechanism where one cryptocurrency can be exchanged directly for another cryptocurrency, without the need for a trusted third party such as an exchange.[98]
ATMs
Jordan Kelley, founder of Robocoin, launched the first Bitcoin ATM in the United States on 20 February 2014. The kiosk installed in Austin, Texas, is similar to bank ATMs but has scanners to read government-issued identification such as a driver’s license or a passport to confirm users’ identities.[99]
Initial coin offerings
An initial coin offering (ICO) is a controversial means of raising funds for a new cryptocurrency venture. An ICO may be used by startups with the intention of avoiding regulation. However, securities regulators in many jurisdictions, including in the U.S., and Canada, have indicated that if a coin or token is an «investment contract» (e.g., under the Howey test, i.e., an investment of money with a reasonable expectation of profit based significantly on the entrepreneurial or managerial efforts of others), it is a security and is subject to securities regulation. In an ICO campaign, a percentage of the cryptocurrency (usually in the form of «tokens») is sold to early backers of the project in exchange for legal tender or other cryptocurrencies, often Bitcoin or Ether.[100][101][102]
According to PricewaterhouseCoopers, four of the 10 biggest proposed initial coin offerings have used Switzerland as a base, where they are frequently registered as non-profit foundations. The Swiss regulatory agency FINMA stated that it would take a «balanced approach» to ICO projects and would allow «legitimate innovators to navigate the regulatory landscape and so launch their projects in a way consistent with national laws protecting investors and the integrity of the financial system.» In response to numerous requests by industry representatives, a legislative ICO working group began to issue legal guidelines in 2018, which are intended to remove uncertainty from cryptocurrency offerings and to establish sustainable business practices.[103]
Price trends
The market capitalization of a cryptocurrency is calculated by multiplying the price by the number of coins in circulation. The total cryptocurrency market cap has historically been dominated by Bitcoin accounting for at least 50% of the market cap value where altcoins have increased and decreased in market cap value in relation to Bitcoin. Bitcoin’s value is largely determined by speculation among other technological limiting factors known as blockchain rewards coded into the architecture technology of Bitcoin itself. The cryptocurrency market cap follows a trend known as the «halving», which is when the block rewards received from Bitcoin are halved due to technological mandated limited factors instilled into Bitcoin which in turn limits the supply of Bitcoin. As the date reaches near of a halving (twice thus far historically) the cryptocurrency market cap increases, followed by a downtrend.[104]
By June 2021, cryptocurrency had begun to be offered by some wealth managers in the US for 401(k)s.[105][106][107]
Volatility
Cryptocurrency prices are much more volatile than established financial assets such as stocks. For example, over one week in May 2022, Bitcoin lost 20% of its value and Ethereum lost 26%, while Solana and Cardano lost 41% and 35% respectively. The falls were attributed to warnings about inflation. By comparison, in the same week, the Nasdaq tech stock index fell 7.6 per cent and the FTSE 100 was 3.6 per cent down.[108]
In the longer term, of the 10 leading cryptocurrencies identified by the total value of coins in circulation in January 2018, only four (Bitcoin, Ethereum, Cardano and Ripple (XRP)) were still in that position in early 2022.[109] The total value of all cryptocurrencies was $2 trillion at the end of 2021, but had halved nine months later.[110][111] The Wall Street Journal has commented that the crypto sector has become “intertwined” with the rest of the capital markets and “sensitive to the same forces that drive tech stocks and other risk assets”, such as inflation forecasts.[112]
Databases
There are also centralized databases, outside of blockchains, that store crypto market data. Compared to the blockchain, databases perform fast as there is no verification process. Four of the most popular cryptocurrency market databases are CoinMarketCap, CoinGecko, BraveNewCoin, and Cryptocompare.[113]
Social and political aspects
According to Alan Feuer of The New York Times, libertarians and anarcho-capitalists were attracted to the philosophical idea behind Bitcoin. Early Bitcoin supporter Roger Ver said: «At first, almost everyone who got involved did so for philosophical reasons. We saw Bitcoin as a great idea, as a way to separate money from the state.»[114] Economist Paul Krugman argues that cryptocurrencies like Bitcoin are «something of a cult» based in «paranoid fantasies» of government power.[115]
Nigel Dodd argues in The social life of Bitcoin that the essence of the Bitcoin ideology is to remove money from both social and governmental control.[116] Dodd discusses the «Declaration of Bitcoin’s Independence», a message of crypto-anarchism with the words: «Bitcoin is inherently anti-establishment, anti-system, and anti-state. Bitcoin undermines governments and disrupts institutions because Bitcoin is fundamentally humanitarian.»[117][118]
David Golumbia says that the ideas influencing Bitcoin advocates emerge from right-wing extremist movements such as the Liberty Lobby and the John Birch Society and their anti-Central Bank rhetoric, or, more recently, Ron Paul and Tea Party-style libertarianism.[119] Steve Bannon, who owns a «good stake» in Bitcoin, sees cryptocurrency as a form of disruptive populism, taking control back from central authorities.[120]
Bitcoin’s founder, Satoshi Nakamoto has supported the idea that cryptocurrencies go well with libertarianism: «It’s very attractive to the libertarian viewpoint if we can explain it properly.» Nakamoto said in 2008.[121]
According to the European Central Bank, the decentralization of money offered by Bitcoin has its theoretical roots in the Austrian school of economics, especially with Friedrich von Hayek in his book Denationalisation of Money: The Argument Refined,[122] in which Hayek advocates a complete free market in the production, distribution and management of money to end the monopoly of central banks.[123]
Increasing regulation
The rise in the popularity of cryptocurrencies and their adoption by financial institutions has led some governments to assess whether regulation is needed to protect users. The Financial Action Task Force (FATF) has defined cryptocurrency-related services as «virtual asset service providers» (VASPs) and recommended that they be regulated with the same money laundering (AML) and know your customer (KYC) requirements as financial institutions.[124]
In May 2020, the Joint Working Group on interVASP Messaging Standards published «IVMS 101», a universal common language for communication of required originator and beneficiary information between VASPs. The FATF and financial regulators were informed as the data model was developed.[125]
In June 2020, FATF updated its guidance to include the «Travel Rule» for cryptocurrencies, a measure which mandates that VASPs obtain, hold, and exchange information about the originators and beneficiaries of virtual asset transfers.[126] Subsequent standardized protocol specifications recommended using JSON for relaying data between VASPs and identity services. As of December 2020, the IVMS 101 data model has yet to be finalized and ratified by the three global standard setting bodies that created it.[127]
The European Commission published a digital finance strategy in September 2020. This included a draft regulation on Markets in Crypto-Assets (MiCA), which aimed to provide a comprehensive regulatory framework for digital assets in the EU.[128][129]
On 10 June 2021, the Basel Committee on Banking Supervision proposed that banks that held cryptocurrency assets must set aside capital to cover all potential losses. For instance, if a bank were to hold Bitcoin worth $2 billion, it would be required to set aside enough capital to cover the entire $2 billion. This is a more extreme standard than banks are usually held to when it comes to other assets. However, this is a proposal and not a regulation.
The IMF is seeking a co-ordinated, consistent and comprehensive approach to supervising cryptocurrencies. Tobias Adrian, the IMF’s financial counsellor and head of its monetary and capital markets department said in a January 2022 interview that «Agreeing global regulations is never quick. But if we start now, we can achieve the goal of maintaining financial stability while also enjoying the benefits which the underlying technological innovations bring,»[130]
United States
In 2021, 17 states passed laws and resolutions concerning cryptocurrency regulation.[131] The U.S. Securities and Exchange Commission (SEC) is considering what steps to take. On 8 July 2021, Senator Elizabeth Warren, part of the Senate Banking Committee, wrote to the chairman of the SEC and demanded that it provide answers on cryptocurrency regulation by 28 July 2021,[132][needs update] due to the increase in cryptocurrency exchange use and the danger this poses to consumers. On 17 February 2022, the Justice department named Eun Young Choi as the first director of a National Cryptocurrency Enforcement Team to aid in identification of and dealing with misuse of cryptocurrencies and other digital assets.[133]
China
In September 2017, China banned ICOs to cause abnormal return from cryptocurrency decreasing during announcement window. The liquidity changes by banning ICOs in China was temporarily negative while the liquidity effect became positive after news.[134]
On 18 May 2021, China banned financial institutions and payment companies from being able to provide cryptocurrency transaction related services.[135] This led to a sharp fall in the price of the biggest proof of work cryptocurrencies. For instance, Bitcoin fell 31%, Ethereum fell 44%, Binance Coin fell 32% and Dogecoin fell 30%.[136] Proof of work mining was the next focus, with regulators in popular mining regions citing the use of electricity generated from highly polluting sources such as coal to create Bitcoin and Ethereum.[137]
In September 2021, the Chinese government declared all cryptocurrency transactions of any kind illegal, completing its crackdown on cryptocurrency.[32]
United Kingdom
In the United Kingdom, as of 10 January 2021, all cryptocurrency firms, such as exchanges, advisors and professionals that have either a presence, market product or provide services within the UK market must register with the Financial Conduct Authority. Additionally, on 27 June 2021, the financial watchdog demanded that Binance, the world’s largest cryptocurrency exchange,[138] cease all regulated activities in the UK.[139]
South Africa
South Africa, which has seen a large number of scams related to cryptocurrency, is said to be putting a regulatory timeline in place that will produce a regulatory framework.[140] The largest scam occurred in April 2021, where the two founders of an African-based cryptocurrency exchange called Africrypt, Raees Cajee and Ameer Cajee, disappeared with $3.8 billion worth of Bitcoin.[141] Additionally, Mirror Trading International disappeared with $170 million worth of cryptocurrency in January 2021.[141]
South Korea
In March 2021, South Korea implemented new legislation to strengthen their oversight of digital assets. This legislation requires all digital asset managers, providers and exchanges to be registered with the Korea Financial Intelligence Unit in order to operate in South Korea.[142] Registering with this unit requires that all exchanges are certified by the Information Security Management System and that they ensure all customers have real name bank accounts. It also requires that the CEO and board members of the exchanges have not been convicted of any crimes and that the exchange holds sufficient levels of deposit insurance to cover losses arising from hacks.[142]
Turkey
On 30 April 2021, the Central Bank of the Republic of Turkey banned the use of cryptocurrencies and cryptoassets for making purchases on the grounds that the use of cryptocurrencies for such payments poses significant transaction risks.[143]
El Salvador
On 9 June 2021, El Salvador announced that it will adopt Bitcoin as legal tender, the first country to do so.[144]
India
At present, India neither prohibits nor allows investment in the cryptocurrency market. In 2020, the Supreme Court of India had lifted the ban on cryptocurrency, which was imposed by the Reserve Bank of India.[145][146][147][148] Since then, an investment in cryptocurrency is considered legitimate, though there is still ambiguity about the issues regarding the extent and payment of tax on the income accrued thereupon and also its regulatory regime. But it is being contemplated that the Indian Parliament will soon pass a specific law to either ban or regulate the cryptocurrency market in India.[149] Expressing his public policy opinion on the Indian cryptocurrency market to a well-known online publication, a leading public policy lawyer and Vice President of SAARCLAW (South Asian Association for Regional Co-operation in Law) Hemant Batra has said that the «cryptocurrency market has now become very big with involvement of billions of dollars in the market hence, it is now unattainable and irreconcilable for the government to completely ban all sorts of cryptocurrency and its trading and investment».[150] He mooted regulating the cryptocurrency market rather than completely banning it. He favoured following IMF and FATF guidelines in this regard.
Switzerland
Switzerland was one of the first countries to implement the FATF’s Travel Rule. FINMA, the Swiss regulator, issued its own guidance to VASPs in 2019. The guidance followed the FATF’s Recommendation 16, however with stricter requirements. According to FINMA’s[151] requirements, VASPs need to verify the identity of the beneficiary of the transfer.
Legality
The legal status of cryptocurrencies varies substantially from country to country and is still undefined or changing in many of them. At least one study has shown that broad generalizations about the use of Bitcoin in illicit finance are significantly overstated and that blockchain analysis is an effective crime fighting and intelligence gathering tool.[152] While some countries have explicitly allowed their use and trade,[153] others have banned or restricted it. According to the Library of Congress in 2018, an «absolute ban» on trading or using cryptocurrencies applies in eight countries: Algeria, Bolivia, Egypt, Iraq, Morocco, Nepal, Pakistan, and the United Arab Emirates. An «implicit ban» applies in another 15 countries, which include Bahrain, Bangladesh, China, Colombia, the Dominican Republic, Indonesia, Iran, Kuwait, Lesotho, Lithuania, Macau, Oman, Qatar, Saudi Arabia and Taiwan.[154] In the United States and Canada, state and provincial securities regulators, coordinated through the North American Securities Administrators Association, are investigating «Bitcoin scams» and ICOs in 40 jurisdictions.[155]
Various government agencies, departments, and courts have classified Bitcoin differently. China Central Bank banned the handling of Bitcoins by financial institutions in China in early 2014.
In Russia, though owning cryptocurrency is legal, its residents are only allowed to purchase goods from other residents using the Russian ruble while nonresidents are allowed to use foreign currency.[156] Regulations and bans that apply to Bitcoin probably extend to similar cryptocurrency systems.[157]
In August 2018, the Bank of Thailand announced its plans to create its own cryptocurrency, the Central Bank Digital Currency (CBDC).[158]
Advertising bans
Cryptocurrency advertisements have been banned on the following platforms:
- Google[159]
- Twitter[159]
- Facebook[159]
- Bing[160]
- Snapchat
- LinkedIn[161]
- MailChimp[162]
- Baidu
- Tencent
- Line
- Yandex[161]
U.S. tax status
On 25 March 2014, the United States Internal Revenue Service (IRS) ruled that Bitcoin will be treated as property for tax purposes. Therefore, virtual currencies are considered commodities subject to capital gains tax.[163]
The legal concern of an unregulated global economy
As the popularity and demand for online currencies has increased since the inception of Bitcoin in 2009,[164] so have concerns that such an unregulated person to person global economy that cryptocurrencies offer may become a threat to society. Concerns abound that altcoins may become tools for anonymous web criminals.[165]
Cryptocurrency networks display a lack of regulation that has been criticized as enabling criminals who seek to evade taxes and launder money. Money laundering issues are also present in regular bank transfers, however with bank-to-bank wire transfers for instance, the account holder must at least provide a proven identity.
Transactions that occur through the use and exchange of these altcoins are independent from formal banking systems, and therefore can make tax evasion simpler for individuals. Since charting taxable income is based upon what a recipient reports to the revenue service, it becomes extremely difficult to account for transactions made using existing cryptocurrencies, a mode of exchange that is complex and difficult to track.[165]
Systems of anonymity that most cryptocurrencies offer can also serve as a simpler means to launder money. Rather than laundering money through an intricate net of financial actors and offshore bank accounts, laundering money through altcoins can be achieved through anonymous transactions.[165]
Cryptocurrency makes legal enforcement against extremist groups more complicated, which consequently strengthens them.[166] White supremacist Richard Spencer went as far as to declare Bitcoin the “currency of the alt-right.”[167]
Loss, theft, and fraud
In February 2014, the world’s largest Bitcoin exchange, Mt. Gox, declared bankruptcy. Likely due to theft, the company claimed that it had lost nearly 750,000 Bitcoins belonging to their clients. This added up to approximately 7% of all Bitcoins in existence, worth a total of $473 million. Mt. Gox blamed hackers, who had exploited the transaction malleability problems in the network. The price of a Bitcoin fell from a high of about $1,160 in December to under $400 in February.[168]
On 21 November 2017, Tether announced that it had been hacked, losing $31 million in USDT from its core treasury wallet.[169]
On 7 December 2017, Slovenian cryptocurrency exchange Nicehash reported that hackers had stolen over $70M using a hijacked company computer.[170]
On 19 December 2017, Yapian, the owner of South Korean exchange Youbit, filed for bankruptcy after suffering two hacks that year.[171][172] Customers were still granted access to 75% of their assets.
In May 2018, Bitcoin Gold had its transactions hijacked and abused by unknown hackers.[173] Exchanges lost an estimated $18m and Bitcoin Gold was delisted from Bittrex after it refused to pay its share of the damages.
On 13 September 2018, Homero Josh Garza was sentenced to 21 months of imprisonment, followed by three years of supervised release.[174] Garza had founded the cryptocurrency startups GAW Miners and ZenMiner in 2014, acknowledged in a plea agreement that the companies were part of a pyramid scheme, and pleaded guilty to wire fraud in 2015. The U.S. Securities and Exchange Commission separately brought a civil enforcement action against Garza, who was eventually ordered to pay a judgment of $9.1 million plus $700,000 in interest. The SEC’s complaint stated that Garza, through his companies, had fraudulently sold «investment contracts representing shares in the profits they claimed would be generated» from mining.[175]
In January 2018, Japanese exchange Coincheck reported that hackers had stolen $530M worth of cryptocurrencies.[176]
In June 2018, South Korean exchange Coinrail was hacked, losing over $37M worth of cryptos.[177] The hack worsened an already ongoing cryptocurrency selloff by an additional $42 billion.[178]
On 9 July 2018, the exchange Bancor, whose code and fundraising had been subjects of controversy, had $23.5 million in cryptocurrency stolen.[179]
A 2020 EU report found that users had lost crypto-assets worth hundreds of millions of US dollars in security breaches at exchanges and storage providers. Between 2011 and 2019, reported breaches ranged from four to twelve a year. In 2019, more than a billion dollars worth of cryptoassets was reported stolen. Stolen assets «typically find their way to illegal markets and are used to fund further criminal activity».[180]
According to a 2020 report produced by the United States Attorney General’s Cyber-Digital Task Force, the following three categories make up the majority of illicit cryptocurrency uses: «(1) financial transactions associated with the commission of crimes; (2) money laundering and the shielding of legitimate activity from tax, reporting, or other legal requirements; or (3) crimes, such as theft, directly implicating the cryptocurrency marketplace itself.» The report concludes that «for cryptocurrency to realize its truly transformative potential, it is imperative that these risks be addressed» and that «the government has legal and regulatory tools available at its disposal to confront the threats posed by cryptocurrency’s illicit uses».[181][182]
According to the UK 2020 national risk assessment—a comprehensive assessment of money laundering and terrorist financing risk in the UK—the risk of using cryptoassets such as Bitcoin for money laundering and terrorism financing is assessed as «medium» (from «low» in the previous 2017 report).[183] Legal scholars suggested that the money laundering opportunities may be more perceived than real.[184] Blockchain analysis company Chainalysis concluded that illicit activities like cybercrime, money laundering and terrorism financing made up only 0.15% of all crypto transactions conducted in 2021, representing a total of $14 billion.[185][186][187]
In December 2021, Monkey Kingdom — a NFT project based in Hong Kong lost US$1.3 million worth of cryptocurrencies via a phishing link used by the hacker.[188]
Money laundering
According to blockchain data company Chainalysis, criminals laundered US$8,600,000,000 worth of cryptocurrency in 2021, up by 30% from the previous year.[189] The data suggests that rather than managing numerous illicit havens, cybercriminals make use of a small group of purpose built centralized exchanges for sending and receiving illicit cryptocurrency. In 2021, those exchanges received 47% of funds sent by crime linked addresses.[190] Almost $2.2bn worth of cryptocurrencies was embezzled from DeFi protocols in 2021, which represents 72% of all cryptocurrency theft in 2021.
According to Bloomberg and the New York Times, Federation Tower, a two skyscraper complex in the heart of Moscow City, is home to many cryptocurrency businesses under suspicion of facilitating extensive money laundering, including accepting illicit cryptocurrency funds obtained through scams, darknet markets, and ransomware.[191] Notable businesses include Garantex, Eggchange, Cashbank, Buy-Bitcoin, Tetchange, Bitzlato, and Suex, which was sanctioned by the U.S. in 2021.
Dark money has also been flowing into Russia through a dark web marketplace called Hydra, which is powered by cryptocurrency, and enjoyed more than $1 billion in sales in 2020, according to Chainalysis.[192] The platform demands that sellers liquidate cryptocurrency only through certain regional exchanges, which has made it difficult for investigators to trace the money.
Almost 74% of ransomware revenue in 2021 — over $400 million worth of cryptocurrency — went to software strains likely affiliated with Russia, where oversight is notoriously limited.[191] However, Russians are also leaders in the benign adoption of cryptocurrencies, as the ruble is unreliable, and President Putin favours the idea of «overcoming the excessive domination of the limited number of reserve currencies.»[193]
Darknet markets
Properties of cryptocurrencies gave them popularity in applications such as a safe haven in banking crises and means of payment, which also led to the cryptocurrency use in controversial settings in the form of online black markets, such as Silk Road.[165] The original Silk Road was shut down in October 2013 and there have been two more versions in use since then. In the year following the initial shutdown of Silk Road, the number of prominent dark markets increased from four to twelve, while the amount of drug listings increased from 18,000 to 32,000.[165]
Darknet markets present challenges in regard to legality. Cryptocurrency used in dark markets are not clearly or legally classified in almost all parts of the world. In the U.S., Bitcoins are labelled as «virtual assets».[citation needed] This type of ambiguous classification puts pressure on law enforcement agencies around the world to adapt to the shifting drug trade of dark markets.[194][unreliable source?]
Wash trades
Various studies have found that crypto-trading is rife with wash trading. Wash trading is a process, illegal in some jurisdictions, involving buyers and sellers being the same person or group, and may be used to manipulate the price of a cryptocurrency or inflate volume artificially. Exchanges with higher volumes can demand higher premiums from token issuers.[195] A study from 2019 concluded that up to 80% of trades on unregulated cryptocurrency exchanges could be wash trades.[195] A 2019 report by Bitwise Asset Management claimed that 95% of all Bitcoin trading volume reported on major website CoinMarketCap had been artificially generated, and of 81 exchanges studied, only 10 provided legitimate volume figures.[196]
As a tool to evade sanctions
In 2022, cryptocurrencies attracted attention when Western nations imposed severe economic sanctions on Russia in the aftermath of its invasion of Ukraine in February. However, American sources warned in March that some crypto-transactions could potentially be used to evade economic sanctions against Russia and Belarus.[197]
In April 2022, the computer programmer Virgil Griffith received a five-year prison sentence in the US for attending a Pyongyang cryptocurrency conference, where he gave a presentation on blockchains which might be used for sanctions evasion.[198]
Impacts and analysis

Cryptocurrencies: looking beyond the hype, Hyun Song Shin, Bank for International Settlements, 2:48[199] |
The Bank for International Settlements summarized several criticisms of cryptocurrencies in Chapter V of their 2018 annual report. The criticisms include the lack of stability in their price, the high energy consumption, high and variable transactions costs, the poor security and fraud at cryptocurrency exchanges, vulnerability to debasement (from forking), and the influence of miners.[199][200][201]
Speculation, fraud, and adoption
Cryptocurrencies have been compared to Ponzi schemes, pyramid schemes[202] and economic bubbles,[203] such as housing market bubbles.[204] Howard Marks of Oaktree Capital Management stated in 2017 that digital currencies were «nothing but an unfounded fad (or perhaps even a pyramid scheme), based on a willingness to ascribe value to something that has little or none beyond what people will pay for it», and compared them to the tulip mania (1637), South Sea Bubble (1720), and dot-com bubble (1999), which all experienced profound price booms and busts.[205]
Regulators in several countries have warned against cryptocurrency and some have taken measures to dissuade users.[206] However, research in 2021 by the UK’s financial regulator suggests such warnings either went unheard, or were ignored. Fewer than one in 10 potential cryptocurrency buyers were aware of consumer warnings on the FCA website, and 12% of crypto users were not aware that their holdings were not protected by statutory compensation.[207][208] Of 1,000 respondents between the ages of eighteen and forty, almost 70% falsely assumed cryptocurrencies were regulated, 75% of younger crypto investors claimed to be driven by competition with friends and family, 58% said that social media enticed them to make high risk investments.[209] The FCA recommends making use of its warning list, which flags unauthorized financial firms.[210]
Many banks do not offer virtual currency services themselves and can refuse to do business with virtual currency companies.[211] In 2014, Gareth Murphy, a senior banking officer, suggested that the widespread adoption of cryptocurrencies may lead to too much money being obfuscated, blinding economists who would use such information to better steer the economy.[212] While traditional financial products have strong consumer protections in place, there is no intermediary with the power to limit consumer losses if Bitcoins are lost or stolen. One of the features cryptocurrency lacks in comparison to credit cards, for example, is consumer protection against fraud, such as chargebacks.
The French regulator Autorité des marchés financiers (AMF) lists 16 websites of companies that solicit investment in cryptocurrency without being authorized to do so in France.[213]
An October 2021 paper by the National Bureau of Economic Research found that Bitcoin suffers from systemic risk as the top 10,000 addresses control about one-third of all Bitcoin in circulation.[214] It’s even worse for Bitcoin miners, with 0.01% controlling 50% of the capacity. According to researcher Flipside Crypto, less than 2% of anonymous accounts control 95% of all available Bitcoin supply.[215] This is considered risky as a great deal of the market is in the hands of a few entities.
A paper by John Griffin, a finance professor at the University of Texas, and Amin Shams, a graduate student found that in 2017 the price of Bitcoin had been substantially inflated using another cryptocurrency, Tether.[216]
Roger Lowenstein, author of «Bank of America: The Epic Struggle to Create the Federal Reserve,» says in a New York Times story that FTX will face over $8 billion in claims.[217]
Non-fungible tokens
Non-fungible tokens (NFTs) are digital assets that represent art, collectibles, gaming, etc. Like crypto, their data is stored on the blockchain. NFTs are bought and traded using cryptocurrency. The Ethereum blockchain was the first place where NFTs were implemented, but now many other blockchains have created their own versions of NFTs. The popularity of NFTs has increased since 2021.[218]
Banks
As the first big Wall Street bank to embrace cryptocurrencies, Morgan Stanley announced on 17 March 2021 that they will be offering access to Bitcoin funds for their wealthy clients through three funds which enable Bitcoin ownership for investors with an aggressive risk tolerance.[219] BNY Mellon on 11 February 2021 announced that it would begin offering cryptocurrency services to its clients.[220]
On 20 April 2021,[221] Venmo added support to its platform to enable customers to buy, hold and sell cryptocurrencies.[222]
In October 2021, financial services company Mastercard announced it is working with digital asset manager Bakkt on a platform that would allow any bank or merchant on the Mastercard network to offer cryptocurrency services.[223]
Environmental impact
Mining for proof-of-work cryptocurrencies requires enormous amounts of electricity and consequently comes with a large carbon footprint due to causing greenhouse gas emissions.[224] Proof-of-work blockchains such as Bitcoin, Ethereum, Litecoin, and Monero were estimated to have added between 3 million and 15 million tonnes of carbon dioxide (CO2) to the atmosphere in the period from 1 January 2016 to 30 June 2017.[225] By November 2018, Bitcoin was estimated to have an annual energy consumption of 45.8TWh, generating 22.0 to 22.9 million tonnes of CO2, rivalling nations like Jordan and Sri Lanka.[226] By the end of 2021, Bitcoin was estimated to produce 65.4 million tonnes of CO2, as much as Greece,[227] and consume between 91 and 177 terawatt-hours annually.[228][229]
Critics have also identified a large electronic waste problem in disposing of mining rigs.[230] Mining hardware is improving at a fast rate, quickly resulting in older generations of hardware.[231]
Bitcoin is the least energy-efficient cryptocurrency, using 707.6 kilowatt-hours of electricity per transaction.[232]
The world’s second-largest cryptocurrency, Ethereum, uses 62.56 kilowatt-hours of electricity per transaction.[233] XRP is the world’s most energy efficient cryptocurrency, using 0.0079 kilowatt-hours of electricity per transaction.[234]
Although the biggest PoW blockchains consume energy on the scale of medium-sized countries, the annual power demand from proof-of-stake (PoS) blockchains is on a scale equivalent to a housing estate. The Times identified six «environmentally friendly» cryptocurrencies: Chia, IOTA, Cardano, Nano, Solarcoin and Bitgreen.[235] Academics and researchers have used various methods for estimating the energy use and energy efficiency of blockchains. A study of the six largest proof-of-stake networks in May 2021 concluded:
- Cardano has the lowest electricity use per node;
- Polkadot has the lowest electricity use overall; and
- Solana has the lowest electricity use per transaction.
In terms of annual consumption (kWh/yr), the figures were: Polkadot (70,237), Tezos (113,249), Avalanche (489,311), Algorand (512,671), Cardano (598,755) and Solana (1,967,930). This equates to Polkadot consuming 7 times the electricity of an average U.S. home, Cardano 57 homes and Solana 200 times as much. The research concluded that PoS networks consumed 0.001% the electricity of the Bitcoin network.[236] University College London researchers reached a similar conclusion.[237]
Variable renewable energy power stations could invest in Bitcoin mining to reduce curtailment, hedge electricity price risk, stabilize the grid, increase the profitability of renewable energy power stations and therefore accelerate transition to sustainable energy.[238][239][240][241][242]
Technological limitations
There are also purely technical elements to consider. For example, technological advancement in cryptocurrencies such as Bitcoin result in high up-front costs to miners in the form of specialized hardware and software.[243] Cryptocurrency transactions are normally irreversible after a number of blocks confirm the transaction. Additionally, cryptocurrency private keys can be permanently lost from local storage due to malware, data loss or the destruction of the physical media. This precludes the cryptocurrency from being spent, resulting in its effective removal from the markets.[244]
Academic studies
In September 2015, the establishment of the peer-reviewed academic journal Ledger (ISSN 2379-5980) was announced. It covers studies of cryptocurrencies and related technologies, and is published by the University of Pittsburgh.[245]
The journal encourages authors to digitally sign a file hash of submitted papers, which will then be timestamped into the Bitcoin blockchain. Authors are also asked to include a personal Bitcoin address in the first page of their papers.[246][247]
Aid agencies
A number of aid agencies have started accepting donations in cryptocurrencies, including UNICEF.[248] Christopher Fabian, principal adviser at UNICEF Innovation, said the children’s fund would uphold donor protocols, meaning that people making donations online would have to pass checks before they were allowed to deposit funds.[249][250]
However, in 2021, there was a backlash against donations in Bitcoin because of the environmental emissions it caused. Some agencies stopped accepting Bitcoin and others turned to «greener» cryptocurrencies.[251] The U.S. arm of Greenpeace stopped accepting bitcoin donations after seven years. It said: «As the amount of energy needed to run Bitcoin became clearer, this policy became no longer tenable.»[252]
In 2022, the Ukrainian government raised over US$10,000,000 worth of aid through cryptocurrency following the 2022 Russian invasion of Ukraine.[253]
Criticism
Bitcoin has been characterized as a speculative bubble by eight winners of the Nobel Memorial Prize in Economic Sciences: Paul Krugman,[254] Robert J. Shiller,[255] Joseph Stiglitz,[256] Richard Thaler,[257] James Heckman,[258] Thomas Sargent,[258] Angus Deaton,[258] and Oliver Hart;[258] and by central bank officials including Alan Greenspan,[259] Agustín Carstens,[260] Vítor Constâncio,[261] and Nout Wellink.[262]
The investors Warren Buffett and George Soros have respectively characterized it as a «mirage»[263] and a «bubble»;[264] while the business executives Jack Ma and J.P. Morgan Chase CEO Jamie Dimon have called it a «bubble»[265] and a «fraud»,[266] respectively, although Jamie Dimon later said he regretted dubbing Bitcoin a fraud.[267] BlackRock CEO Laurence D. Fink called Bitcoin an «index of money laundering».[268]
In June 2022, Bill Gates said that cryptocurrencies are «100% based on greater fool theory».[269]
In 2018, an increase in crypto-related suicides was noticed after the cryptocurrency market crashed in August. The situation was particularly critical in Korea as crypto traders were on «suicide watch». A cryptocurrency forum on Reddit even started providing suicide prevention support to affected investors.[270][271][272]
The May 2022 collapse of the Luna currency operated by Terra also led to reports of suicidal investors in crypto-related subreddits.[273]

A cryptocurrency, crypto-currency, or crypto is a digital currency designed to work as a medium of exchange through a computer network that is not reliant on any central authority, such as a government or bank, to uphold or maintain it.[2] It is a decentralized system for verifying that the parties to a transaction have the money they claim to have, eliminating the need for traditional intermediaries, such as banks, when funds are being transferred between two entities.[3]
Individual coin ownership records are stored in a digital ledger, which is a computerized database using strong cryptography to secure transaction records, control the creation of additional coins, and verify the transfer of coin ownership.[4][5][6] Despite their name, cryptocurrencies are not considered to be currencies in the traditional sense, and while varying treatments have been applied to them, including classification as commodities, securities, and currencies, cryptocurrencies are generally viewed as a distinct asset class in practice.[7][8][9] Some crypto schemes use validators to maintain the cryptocurrency. In a proof-of-stake model, owners put up their tokens as collateral. In return, they get authority over the token in proportion to the amount they stake. Generally, these token stakers get additional ownership in the token over time via network fees, newly minted tokens, or other such reward mechanisms.[10]
Cryptocurrency does not exist in physical form (like paper money) and is typically not issued by a central authority. Cryptocurrencies typically use decentralized control as opposed to a central bank digital currency (CBDC).[11] When a cryptocurrency is minted, or created prior to issuance, or issued by a single issuer, it is generally considered centralized. When implemented with decentralized control, each cryptocurrency works through distributed ledger technology, typically a blockchain, that serves as a public financial transaction database.[12] Traditional asset classes like currencies, commodities, and stocks, as well as macroeconomic factors, have modest exposures to cryptocurrency returns.[13]
The first decentralized cryptocurrency was Bitcoin, which was first released as open-source software in 2009. As of March 2022, there were more than 9,000 other cryptocurrencies in the marketplace, of which more than 70 had a market capitalization exceeding $1 billion.[14]
History
In 1983, American cryptographer David Chaum conceived of a type of cryptographic electronic money called ecash.[15][16] Later, in 1995, he implemented it through Digicash,[17] an early form of cryptographic electronic payments. Digicash required user software in order to withdraw notes from a bank and designate specific encrypted keys before it can be sent to a recipient. This allowed the digital currency to be untraceable by a third party.
In 1996, the National Security Agency published a paper entitled How to Make a Mint: the Cryptography of Anonymous Electronic Cash, describing a cryptocurrency system. The paper was first published in an MIT mailing list[18] and later in 1997 in The American Law Review.[19]
In the 1997 book The Sovereign Individual, the authors, William Rees-Mogg and James Dale Davidson, predicted that the currency used in the information age would be using «mathematical algorithms that have no physical existence»,[20] which has led some in the cryptocurrency community to call the book’s claim a «prophecy».[21]
In 1998, Wei Dai described «b-money», an anonymous, distributed electronic cash system.[22] Shortly thereafter, Nick Szabo described bit gold.[23] Like Bitcoin and other cryptocurrencies that would follow it, bit gold (not to be confused with the later gold-based exchange BitGold) was described as an electronic currency system which required users to complete a proof of work function with solutions being cryptographically put together and published.
In January 2009, Bitcoin was created by pseudonymous developer Satoshi Nakamoto. It used SHA-256, a cryptographic hash function, in its proof-of-work scheme.[24][25] In April 2011, Namecoin was created as an attempt at forming a decentralized DNS. In October 2011, Litecoin was released which used scrypt as its hash function instead of SHA-256. Peercoin, created in August 2012, used a hybrid of proof-of-work and proof-of-stake.[26]
On 6 August 2014, the UK announced its Treasury had commissioned a study of cryptocurrencies, and what role, if any, they could play in the UK economy. The study was also to report on whether regulation should be considered.[27] Its final report was published in 2018,[28] and it issued a consultation on cryptoassets and stablecoins in January 2021.[29]
In June 2021, El Salvador became the first country to accept Bitcoin as legal tender, after the Legislative Assembly had voted 62–22 to pass a bill submitted by President Nayib Bukele classifying the cryptocurrency as such.[30]
In August 2021, Cuba followed with Resolution 215 to recognize and regulate cryptocurrencies such as Bitcoin.[31]
In September 2021, the government of China, the single largest market for cryptocurrency, declared all cryptocurrency transactions illegal. This completed a crackdown on cryptocurrency that had previously banned the operation of intermediaries and miners within China.[32]
On 15 September 2022, the world second largest cryptocurrency at that time, Ethereum transitioned its consensus mechanism from proof-of-work (PoW) to proof-of-stake (PoS) in an upgrade process known as «the Merge». According to the Ethereum Founder, the upgrade can cut Ethereum’s energy use by 99.9% and carbon-dioxide emissions by 99.9%.[33]
On 11 November 2022, FTX Trading Ltd., a cryptocurrency exchange, which also operated a crypto hedge fund, and had been valued at $18 billion,[34] filed for bankruptcy.[35] The financial impact of the collapse extended beyond the immediate FTX customer base, as reported,[36] while, at a Reuters conference, financial industry executives said that «regulators must step in to protect crypto investors.»[37] Technology analyst Avivah Litan commented on the cryptocurrency ecosystem that «everything…needs to improve dramatically in terms of user experience, controls, safety, customer service.»[38]
Formal definition
According to Jan Lansky, a cryptocurrency is a system that meets six conditions:[39]
- The system does not require a central authority; its state is maintained through distributed consensus.
- The system keeps an overview of cryptocurrency units and their ownership.
- The system defines whether new cryptocurrency units can be created. If new cryptocurrency units can be created, the system defines the circumstances of their origin and how to determine the ownership of these new units.
- Ownership of cryptocurrency units can be proved exclusively cryptographically.
- The system allows transactions to be performed in which ownership of the cryptographic units is changed. A transaction statement can only be issued by an entity proving the current ownership of these units.
- If two different instructions for changing the ownership of the same cryptographic units are simultaneously entered, the system performs at most one of them.
In March 2018, the word cryptocurrency was added to the Merriam-Webster Dictionary.[40]
Altcoins
Tokens, cryptocurrencies, and other digital assets other than Bitcoin are collectively known as alternative cryptocurrencies,[41][42][43] typically shortened to «altcoins» or «alt coins»,[44][45] or disparagingly «shitcoins».[46] Paul Vigna of The Wall Street Journal also described altcoins as «alternative versions of Bitcoin»[47] given its role as the model protocol for altcoin designers.
The logo of Ethereum, the second largest cryptocurrency
Altcoins often have underlying differences when compared to Bitcoin. For example, Litecoin aims to process a block every 2.5 minutes, rather than Bitcoin’s 10 minutes, which allows Litecoin to confirm transactions faster than Bitcoin.[48] Another example is Ethereum, which has smart contract functionality that allows decentralized applications to be run on its blockchain.[49] Ethereum was the most used blockchain in 2020, according to Bloomberg News.[50] In 2016, it had the largest «following» of any altcoin, according to the New York Times.[51]
Significant rallies across altcoin markets are often referred to as an «altseason».[52][53]
Stablecoins
Stablecoins are cryptocurrencies designed to maintain a stable level of purchasing power.[54] Notably, these designs are not foolproof, as a number of stablecoins have crashed or lost their peg. For example, on 11 May 2022, Terra’s stablecoin UST fell from $1 to 26 cents.[55][56] The subsequent failure of Terraform Labs resulted in the loss of nearly $40B invested in the Terra and Luna bitcoins.[57] In September 2022, South Korean prosecutors requested the issuance of an Interpol Red Notice against the company’s founder, Do Kwon.[58]
Architecture
Cryptocurrency is produced by an entire cryptocurrency system collectively, at a rate which is defined when the system is created and which is publicly stated. In centralized banking and economic systems such as the US Federal Reserve System, corporate boards or governments control the supply of currency.[citation needed] In the case of cryptocurrency, companies or governments cannot produce new units, and have not so far provided backing for other firms, banks or corporate entities which hold asset value measured in it. The underlying technical system upon which cryptocurrencies are based was created by Satoshi Nakamoto.[59]
Within a proof-of-work system such as Bitcoin, the safety, integrity and balance of ledgers is maintained by a community of mutually distrustful parties referred to as miners. Miners use their computers to help validate and timestamp transactions, adding them to the ledger in accordance with a particular timestamping scheme.[24] In a proof-of-stake blockchain, transactions are validated by holders of the associated cryptocurrency, sometimes grouped together in stake pools.
Most cryptocurrencies are designed to gradually decrease the production of that currency, placing a cap on the total amount of that currency that will ever be in circulation.[60] Compared with ordinary currencies held by financial institutions or kept as cash on hand, cryptocurrencies can be more difficult for seizure by law enforcement.[4]
Blockchain
The validity of each cryptocurrency’s coins is provided by a blockchain. A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography.[59][61] Each block typically contains a hash pointer as a link to a previous block,[61] a timestamp and transaction data.[62] By design, blockchains are inherently resistant to modification of the data. It is «an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way».[63] For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority.
Blockchains are secure by design and are an example of a distributed computing system with high Byzantine fault tolerance. Decentralized consensus has therefore been achieved with a blockchain.[64]
Nodes
A node is a computer that connects to a cryptocurrency network. The node supports the cryptocurrency’s network through either relaying transactions, validation, or hosting a copy of the blockchain. In terms of relaying transactions, each network computer (node) has a copy of the blockchain of the cryptocurrency it supports. When a transaction is made, the node creating the transaction broadcasts details of the transaction using encryption to other nodes throughout the node network so that the transaction (and every other transaction) is known.
Node owners are either volunteers, those hosted by the organization or body responsible for developing the cryptocurrency blockchain network technology, or those who are enticed to host a node to receive rewards from hosting the node network.[65]
Timestamping
Cryptocurrencies use various timestamping schemes to «prove» the validity of transactions added to the blockchain ledger without the need for a trusted third party.
The first timestamping scheme invented was the proof-of-work scheme. The most widely used proof-of-work schemes are based on SHA-256 and scrypt.[26]
Some other hashing algorithms that are used for proof-of-work include CryptoNight, Blake, SHA-3, and X11.
Another method is called the proof-of-stake scheme. Proof-of-stake is a method of securing a cryptocurrency network and achieving distributed consensus through requesting users to show ownership of a certain amount of currency. It is different from proof-of-work systems that run difficult hashing algorithms to validate electronic transactions. The scheme is largely dependent on the coin, and there’s currently no standard form of it. Some cryptocurrencies use a combined proof-of-work and proof-of-stake scheme.[26]
Mining
On a blockchain, mining is the validation of transactions. For this effort, successful miners obtain new cryptocurrency as a reward. The reward decreases transaction fees by creating a complementary incentive to contribute to the processing power of the network. The rate of generating hashes, which validate any transaction, has been increased by the use of specialized machines such as FPGAs and ASICs running complex hashing algorithms like SHA-256 and scrypt.[66] This arms race for cheaper-yet-efficient machines has existed since Bitcoin was introduced in 2009.[66]
With more people venturing into the world of virtual currency, generating hashes for validation has become more complex over time, forcing miners to invest increasingly large sums of money to improve computing performance. Consequently, the reward for finding a hash has diminished and often does not justify the investment in equipment and cooling facilities (to mitigate the heat the equipment produces), and the electricity required to run them.[67] Popular regions for mining include those with inexpensive electricity, a cold climate, and jurisdictions with clear and conducive regulations. By July 2019, Bitcoin’s electricity consumption was estimated to be approximately 7 gigawatts, around 0.2% of the global total, or equivalent to the energy consumed nationally by Switzerland.[68]
Some miners pool resources, sharing their processing power over a network to split the reward equally, according to the amount of work they contributed to the probability of finding a block. A «share» is awarded to members of the mining pool who present a valid partial proof-of-work.
As of February 2018, the Chinese Government has halted trading of virtual currency, banned initial coin offerings and shut down mining. Many Chinese miners have since relocated to Canada[69] and Texas.[70] One company is operating data centers for mining operations at Canadian oil and gas field sites, due to low gas prices.[71] In June 2018, Hydro Quebec proposed to the provincial government to allocate 500 megawatts of power to crypto companies for mining.[72] According to a February 2018 report from Fortune, Iceland has become a haven for cryptocurrency miners in part because of its cheap electricity.[73]
In March 2018, the city of Plattsburgh, New York put an 18-month moratorium on all cryptocurrency mining in an effort to preserve natural resources and the «character and direction» of the city.[74] In 2021, Kazakhstan became the second-biggest crypto-currency mining country, producing 18.1% of the global hash rate. The country built a compound containing 50,000 computers near Ekibastuz.[75]
GPU price rise
An increase in cryptocurrency mining increased the demand for graphics cards (GPU) in 2017.[76] The computing power of GPUs makes them well-suited to generating hashes. Popular favorites of cryptocurrency miners such as Nvidia’s GTX 1060 and GTX 1070 graphics cards, as well as AMD’s RX 570 and RX 580 GPUs, doubled or tripled in price – or were out of stock.[77] A GTX 1070 Ti which was released at a price of $450 sold for as much as $1,100. Another popular card, the GTX 1060 (6 GB model) was released at an MSRP of $250, and sold for almost $500. RX 570 and RX 580 cards from AMD were out of stock for almost a year. Miners regularly buy up the entire stock of new GPU’s as soon as they are available.[78]
Nvidia has asked retailers to do what they can when it comes to selling GPUs to gamers instead of miners. Boris Böhles, PR manager for Nvidia in the German region, said: «Gamers come first for Nvidia.»[79]
Wallets
An example paper printable Bitcoin wallet consisting of one Bitcoin address for receiving and the corresponding private key for spending
A cryptocurrency wallet is a means of storing the public and private «keys» (address) or seed which can be used to receive or spend the cryptocurrency.[80] With the private key, it is possible to write in the public ledger, effectively spending the associated cryptocurrency. With the public key, it is possible for others to send currency to the wallet.
There exist multiple methods of storing keys or seed in a wallet. These methods range from using paper wallets (which are public, private or seed keys written on paper), to using hardware wallets (which are hardware to store your wallet information), to a digital wallet (which is a computer with a software hosting your wallet information), to hosting your wallet using an exchange where cryptocurrency is traded, or by storing your wallet information on a digital medium such as plaintext.[81]
Anonymity
Bitcoin is pseudonymous, rather than anonymous; the cryptocurrency in a wallet is not tied to a person, but rather to one or more specific keys (or «addresses»).[82] Thereby, Bitcoin owners are not immediately identifiable, but all transactions are publicly available in the blockchain.[83] Still, cryptocurrency exchanges are often required by law to collect the personal information of their users.[84]
Some cryptocurrencies, such as Monero, Zerocoin, Zerocash, and CryptoNote, implement additional measures to increase privacy, such as by using zero-knowledge proofs.[85][86]
Economics
Cryptocurrencies are used primarily outside banking and governmental institutions and are exchanged over the Internet.
Block rewards
Proof-of-work cryptocurrencies, such as Bitcoin, offer block rewards incentives for miners. There has been an implicit belief that whether miners are paid by block rewards or transaction fees does not affect the security of the blockchain, but a study suggests that this may not be the case under certain circumstances.[87]
The rewards paid to miners increase the supply of the cryptocurrency. By making sure that verifying transactions is a costly business, the integrity of the network can be preserved as long as benevolent nodes control a majority of computing power. The verification algorithm requires a lot of processing power, and thus electricity in order to make verification costly enough to accurately validate public blockchain. Not only do miners have to factor in the costs associated with expensive equipment necessary to stand a chance of solving a hash problem, they further must consider the significant amount of electrical power in search of the solution. Generally, the block rewards outweigh electricity and equipment costs, but this may not always be the case.[88]
The current value, not the long-term value, of the cryptocurrency supports the reward scheme to incentivize miners to engage in costly mining activities.[89] Some sources[weasel words] claim that the current Bitcoin design is very inefficient, generating a welfare loss of 1.4% relative to an efficient cash system. The main source for this inefficiency is the large mining cost, which is estimated to be US$360 million per year. This translates into users being willing to accept a cash system with an inflation rate of 230% before being better off using Bitcoin as a means of payment. However, the efficiency of the Bitcoin system can be significantly improved by optimizing the rate of coin creation and minimizing transaction fees. Another potential improvement is to eliminate inefficient mining activities by changing the consensus protocol altogether.[90]
Transaction fees
Transaction fees for cryptocurrency depend mainly on the supply of network capacity at the time, versus the demand from the currency holder for a faster transaction.[citation needed] The currency holder can choose a specific transaction fee, while network entities process transactions in order of highest offered fee to lowest.[citation needed] Cryptocurrency exchanges can simplify the process for currency holders by offering priority alternatives and thereby determine which fee will likely cause the transaction to be processed in the requested time.[citation needed]
For Ethereum, transaction fees differ by computational complexity, bandwidth use, and storage needs, while Bitcoin transaction fees differ by transaction size and whether the transaction uses SegWit. In September 2018[needs update], the median transaction fee for Ether corresponded to $0.017,[91] while for Bitcoin it corresponded to $0.55.[92]
Some cryptocurrencies have no transaction fees, and instead rely on client-side proof-of-work as the transaction prioritization and anti-spam mechanism.[93][94][95]
Exchanges
Cryptocurrency exchanges allow customers to trade cryptocurrencies[96] for other assets, such as conventional fiat money, or to trade between different digital currencies.
Crypto marketplaces do not guarantee that an investor is completing a purchase or trade at the optimal price. As a result, many investors take advantage of this by using arbitrage to find the difference in price across several markets.[97]
Atomic swaps
Atomic swaps are a mechanism where one cryptocurrency can be exchanged directly for another cryptocurrency, without the need for a trusted third party such as an exchange.[98]
ATMs
Jordan Kelley, founder of Robocoin, launched the first Bitcoin ATM in the United States on 20 February 2014. The kiosk installed in Austin, Texas, is similar to bank ATMs but has scanners to read government-issued identification such as a driver’s license or a passport to confirm users’ identities.[99]
Initial coin offerings
An initial coin offering (ICO) is a controversial means of raising funds for a new cryptocurrency venture. An ICO may be used by startups with the intention of avoiding regulation. However, securities regulators in many jurisdictions, including in the U.S., and Canada, have indicated that if a coin or token is an «investment contract» (e.g., under the Howey test, i.e., an investment of money with a reasonable expectation of profit based significantly on the entrepreneurial or managerial efforts of others), it is a security and is subject to securities regulation. In an ICO campaign, a percentage of the cryptocurrency (usually in the form of «tokens») is sold to early backers of the project in exchange for legal tender or other cryptocurrencies, often Bitcoin or Ether.[100][101][102]
According to PricewaterhouseCoopers, four of the 10 biggest proposed initial coin offerings have used Switzerland as a base, where they are frequently registered as non-profit foundations. The Swiss regulatory agency FINMA stated that it would take a «balanced approach» to ICO projects and would allow «legitimate innovators to navigate the regulatory landscape and so launch their projects in a way consistent with national laws protecting investors and the integrity of the financial system.» In response to numerous requests by industry representatives, a legislative ICO working group began to issue legal guidelines in 2018, which are intended to remove uncertainty from cryptocurrency offerings and to establish sustainable business practices.[103]
Price trends
The market capitalization of a cryptocurrency is calculated by multiplying the price by the number of coins in circulation. The total cryptocurrency market cap has historically been dominated by Bitcoin accounting for at least 50% of the market cap value where altcoins have increased and decreased in market cap value in relation to Bitcoin. Bitcoin’s value is largely determined by speculation among other technological limiting factors known as blockchain rewards coded into the architecture technology of Bitcoin itself. The cryptocurrency market cap follows a trend known as the «halving», which is when the block rewards received from Bitcoin are halved due to technological mandated limited factors instilled into Bitcoin which in turn limits the supply of Bitcoin. As the date reaches near of a halving (twice thus far historically) the cryptocurrency market cap increases, followed by a downtrend.[104]
By June 2021, cryptocurrency had begun to be offered by some wealth managers in the US for 401(k)s.[105][106][107]
Volatility
Cryptocurrency prices are much more volatile than established financial assets such as stocks. For example, over one week in May 2022, Bitcoin lost 20% of its value and Ethereum lost 26%, while Solana and Cardano lost 41% and 35% respectively. The falls were attributed to warnings about inflation. By comparison, in the same week, the Nasdaq tech stock index fell 7.6 per cent and the FTSE 100 was 3.6 per cent down.[108]
In the longer term, of the 10 leading cryptocurrencies identified by the total value of coins in circulation in January 2018, only four (Bitcoin, Ethereum, Cardano and Ripple (XRP)) were still in that position in early 2022.[109] The total value of all cryptocurrencies was $2 trillion at the end of 2021, but had halved nine months later.[110][111] The Wall Street Journal has commented that the crypto sector has become “intertwined” with the rest of the capital markets and “sensitive to the same forces that drive tech stocks and other risk assets”, such as inflation forecasts.[112]
Databases
There are also centralized databases, outside of blockchains, that store crypto market data. Compared to the blockchain, databases perform fast as there is no verification process. Four of the most popular cryptocurrency market databases are CoinMarketCap, CoinGecko, BraveNewCoin, and Cryptocompare.[113]
Social and political aspects
According to Alan Feuer of The New York Times, libertarians and anarcho-capitalists were attracted to the philosophical idea behind Bitcoin. Early Bitcoin supporter Roger Ver said: «At first, almost everyone who got involved did so for philosophical reasons. We saw Bitcoin as a great idea, as a way to separate money from the state.»[114] Economist Paul Krugman argues that cryptocurrencies like Bitcoin are «something of a cult» based in «paranoid fantasies» of government power.[115]
Nigel Dodd argues in The social life of Bitcoin that the essence of the Bitcoin ideology is to remove money from both social and governmental control.[116] Dodd discusses the «Declaration of Bitcoin’s Independence», a message of crypto-anarchism with the words: «Bitcoin is inherently anti-establishment, anti-system, and anti-state. Bitcoin undermines governments and disrupts institutions because Bitcoin is fundamentally humanitarian.»[117][118]
David Golumbia says that the ideas influencing Bitcoin advocates emerge from right-wing extremist movements such as the Liberty Lobby and the John Birch Society and their anti-Central Bank rhetoric, or, more recently, Ron Paul and Tea Party-style libertarianism.[119] Steve Bannon, who owns a «good stake» in Bitcoin, sees cryptocurrency as a form of disruptive populism, taking control back from central authorities.[120]
Bitcoin’s founder, Satoshi Nakamoto has supported the idea that cryptocurrencies go well with libertarianism: «It’s very attractive to the libertarian viewpoint if we can explain it properly.» Nakamoto said in 2008.[121]
According to the European Central Bank, the decentralization of money offered by Bitcoin has its theoretical roots in the Austrian school of economics, especially with Friedrich von Hayek in his book Denationalisation of Money: The Argument Refined,[122] in which Hayek advocates a complete free market in the production, distribution and management of money to end the monopoly of central banks.[123]
Increasing regulation
The rise in the popularity of cryptocurrencies and their adoption by financial institutions has led some governments to assess whether regulation is needed to protect users. The Financial Action Task Force (FATF) has defined cryptocurrency-related services as «virtual asset service providers» (VASPs) and recommended that they be regulated with the same money laundering (AML) and know your customer (KYC) requirements as financial institutions.[124]
In May 2020, the Joint Working Group on interVASP Messaging Standards published «IVMS 101», a universal common language for communication of required originator and beneficiary information between VASPs. The FATF and financial regulators were informed as the data model was developed.[125]
In June 2020, FATF updated its guidance to include the «Travel Rule» for cryptocurrencies, a measure which mandates that VASPs obtain, hold, and exchange information about the originators and beneficiaries of virtual asset transfers.[126] Subsequent standardized protocol specifications recommended using JSON for relaying data between VASPs and identity services. As of December 2020, the IVMS 101 data model has yet to be finalized and ratified by the three global standard setting bodies that created it.[127]
The European Commission published a digital finance strategy in September 2020. This included a draft regulation on Markets in Crypto-Assets (MiCA), which aimed to provide a comprehensive regulatory framework for digital assets in the EU.[128][129]
On 10 June 2021, the Basel Committee on Banking Supervision proposed that banks that held cryptocurrency assets must set aside capital to cover all potential losses. For instance, if a bank were to hold Bitcoin worth $2 billion, it would be required to set aside enough capital to cover the entire $2 billion. This is a more extreme standard than banks are usually held to when it comes to other assets. However, this is a proposal and not a regulation.
The IMF is seeking a co-ordinated, consistent and comprehensive approach to supervising cryptocurrencies. Tobias Adrian, the IMF’s financial counsellor and head of its monetary and capital markets department said in a January 2022 interview that «Agreeing global regulations is never quick. But if we start now, we can achieve the goal of maintaining financial stability while also enjoying the benefits which the underlying technological innovations bring,»[130]
United States
In 2021, 17 states passed laws and resolutions concerning cryptocurrency regulation.[131] The U.S. Securities and Exchange Commission (SEC) is considering what steps to take. On 8 July 2021, Senator Elizabeth Warren, part of the Senate Banking Committee, wrote to the chairman of the SEC and demanded that it provide answers on cryptocurrency regulation by 28 July 2021,[132][needs update] due to the increase in cryptocurrency exchange use and the danger this poses to consumers. On 17 February 2022, the Justice department named Eun Young Choi as the first director of a National Cryptocurrency Enforcement Team to aid in identification of and dealing with misuse of cryptocurrencies and other digital assets.[133]
China
In September 2017, China banned ICOs to cause abnormal return from cryptocurrency decreasing during announcement window. The liquidity changes by banning ICOs in China was temporarily negative while the liquidity effect became positive after news.[134]
On 18 May 2021, China banned financial institutions and payment companies from being able to provide cryptocurrency transaction related services.[135] This led to a sharp fall in the price of the biggest proof of work cryptocurrencies. For instance, Bitcoin fell 31%, Ethereum fell 44%, Binance Coin fell 32% and Dogecoin fell 30%.[136] Proof of work mining was the next focus, with regulators in popular mining regions citing the use of electricity generated from highly polluting sources such as coal to create Bitcoin and Ethereum.[137]
In September 2021, the Chinese government declared all cryptocurrency transactions of any kind illegal, completing its crackdown on cryptocurrency.[32]
United Kingdom
In the United Kingdom, as of 10 January 2021, all cryptocurrency firms, such as exchanges, advisors and professionals that have either a presence, market product or provide services within the UK market must register with the Financial Conduct Authority. Additionally, on 27 June 2021, the financial watchdog demanded that Binance, the world’s largest cryptocurrency exchange,[138] cease all regulated activities in the UK.[139]
South Africa
South Africa, which has seen a large number of scams related to cryptocurrency, is said to be putting a regulatory timeline in place that will produce a regulatory framework.[140] The largest scam occurred in April 2021, where the two founders of an African-based cryptocurrency exchange called Africrypt, Raees Cajee and Ameer Cajee, disappeared with $3.8 billion worth of Bitcoin.[141] Additionally, Mirror Trading International disappeared with $170 million worth of cryptocurrency in January 2021.[141]
South Korea
In March 2021, South Korea implemented new legislation to strengthen their oversight of digital assets. This legislation requires all digital asset managers, providers and exchanges to be registered with the Korea Financial Intelligence Unit in order to operate in South Korea.[142] Registering with this unit requires that all exchanges are certified by the Information Security Management System and that they ensure all customers have real name bank accounts. It also requires that the CEO and board members of the exchanges have not been convicted of any crimes and that the exchange holds sufficient levels of deposit insurance to cover losses arising from hacks.[142]
Turkey
On 30 April 2021, the Central Bank of the Republic of Turkey banned the use of cryptocurrencies and cryptoassets for making purchases on the grounds that the use of cryptocurrencies for such payments poses significant transaction risks.[143]
El Salvador
On 9 June 2021, El Salvador announced that it will adopt Bitcoin as legal tender, the first country to do so.[144]
India
At present, India neither prohibits nor allows investment in the cryptocurrency market. In 2020, the Supreme Court of India had lifted the ban on cryptocurrency, which was imposed by the Reserve Bank of India.[145][146][147][148] Since then, an investment in cryptocurrency is considered legitimate, though there is still ambiguity about the issues regarding the extent and payment of tax on the income accrued thereupon and also its regulatory regime. But it is being contemplated that the Indian Parliament will soon pass a specific law to either ban or regulate the cryptocurrency market in India.[149] Expressing his public policy opinion on the Indian cryptocurrency market to a well-known online publication, a leading public policy lawyer and Vice President of SAARCLAW (South Asian Association for Regional Co-operation in Law) Hemant Batra has said that the «cryptocurrency market has now become very big with involvement of billions of dollars in the market hence, it is now unattainable and irreconcilable for the government to completely ban all sorts of cryptocurrency and its trading and investment».[150] He mooted regulating the cryptocurrency market rather than completely banning it. He favoured following IMF and FATF guidelines in this regard.
Switzerland
Switzerland was one of the first countries to implement the FATF’s Travel Rule. FINMA, the Swiss regulator, issued its own guidance to VASPs in 2019. The guidance followed the FATF’s Recommendation 16, however with stricter requirements. According to FINMA’s[151] requirements, VASPs need to verify the identity of the beneficiary of the transfer.
Legality
The legal status of cryptocurrencies varies substantially from country to country and is still undefined or changing in many of them. At least one study has shown that broad generalizations about the use of Bitcoin in illicit finance are significantly overstated and that blockchain analysis is an effective crime fighting and intelligence gathering tool.[152] While some countries have explicitly allowed their use and trade,[153] others have banned or restricted it. According to the Library of Congress in 2018, an «absolute ban» on trading or using cryptocurrencies applies in eight countries: Algeria, Bolivia, Egypt, Iraq, Morocco, Nepal, Pakistan, and the United Arab Emirates. An «implicit ban» applies in another 15 countries, which include Bahrain, Bangladesh, China, Colombia, the Dominican Republic, Indonesia, Iran, Kuwait, Lesotho, Lithuania, Macau, Oman, Qatar, Saudi Arabia and Taiwan.[154] In the United States and Canada, state and provincial securities regulators, coordinated through the North American Securities Administrators Association, are investigating «Bitcoin scams» and ICOs in 40 jurisdictions.[155]
Various government agencies, departments, and courts have classified Bitcoin differently. China Central Bank banned the handling of Bitcoins by financial institutions in China in early 2014.
In Russia, though owning cryptocurrency is legal, its residents are only allowed to purchase goods from other residents using the Russian ruble while nonresidents are allowed to use foreign currency.[156] Regulations and bans that apply to Bitcoin probably extend to similar cryptocurrency systems.[157]
In August 2018, the Bank of Thailand announced its plans to create its own cryptocurrency, the Central Bank Digital Currency (CBDC).[158]
Advertising bans
Cryptocurrency advertisements have been banned on the following platforms:
- Google[159]
- Twitter[159]
- Facebook[159]
- Bing[160]
- Snapchat
- LinkedIn[161]
- MailChimp[162]
- Baidu
- Tencent
- Line
- Yandex[161]
U.S. tax status
On 25 March 2014, the United States Internal Revenue Service (IRS) ruled that Bitcoin will be treated as property for tax purposes. Therefore, virtual currencies are considered commodities subject to capital gains tax.[163]
The legal concern of an unregulated global economy
As the popularity and demand for online currencies has increased since the inception of Bitcoin in 2009,[164] so have concerns that such an unregulated person to person global economy that cryptocurrencies offer may become a threat to society. Concerns abound that altcoins may become tools for anonymous web criminals.[165]
Cryptocurrency networks display a lack of regulation that has been criticized as enabling criminals who seek to evade taxes and launder money. Money laundering issues are also present in regular bank transfers, however with bank-to-bank wire transfers for instance, the account holder must at least provide a proven identity.
Transactions that occur through the use and exchange of these altcoins are independent from formal banking systems, and therefore can make tax evasion simpler for individuals. Since charting taxable income is based upon what a recipient reports to the revenue service, it becomes extremely difficult to account for transactions made using existing cryptocurrencies, a mode of exchange that is complex and difficult to track.[165]
Systems of anonymity that most cryptocurrencies offer can also serve as a simpler means to launder money. Rather than laundering money through an intricate net of financial actors and offshore bank accounts, laundering money through altcoins can be achieved through anonymous transactions.[165]
Cryptocurrency makes legal enforcement against extremist groups more complicated, which consequently strengthens them.[166] White supremacist Richard Spencer went as far as to declare Bitcoin the “currency of the alt-right.”[167]
Loss, theft, and fraud
In February 2014, the world’s largest Bitcoin exchange, Mt. Gox, declared bankruptcy. Likely due to theft, the company claimed that it had lost nearly 750,000 Bitcoins belonging to their clients. This added up to approximately 7% of all Bitcoins in existence, worth a total of $473 million. Mt. Gox blamed hackers, who had exploited the transaction malleability problems in the network. The price of a Bitcoin fell from a high of about $1,160 in December to under $400 in February.[168]
On 21 November 2017, Tether announced that it had been hacked, losing $31 million in USDT from its core treasury wallet.[169]
On 7 December 2017, Slovenian cryptocurrency exchange Nicehash reported that hackers had stolen over $70M using a hijacked company computer.[170]
On 19 December 2017, Yapian, the owner of South Korean exchange Youbit, filed for bankruptcy after suffering two hacks that year.[171][172] Customers were still granted access to 75% of their assets.
In May 2018, Bitcoin Gold had its transactions hijacked and abused by unknown hackers.[173] Exchanges lost an estimated $18m and Bitcoin Gold was delisted from Bittrex after it refused to pay its share of the damages.
On 13 September 2018, Homero Josh Garza was sentenced to 21 months of imprisonment, followed by three years of supervised release.[174] Garza had founded the cryptocurrency startups GAW Miners and ZenMiner in 2014, acknowledged in a plea agreement that the companies were part of a pyramid scheme, and pleaded guilty to wire fraud in 2015. The U.S. Securities and Exchange Commission separately brought a civil enforcement action against Garza, who was eventually ordered to pay a judgment of $9.1 million plus $700,000 in interest. The SEC’s complaint stated that Garza, through his companies, had fraudulently sold «investment contracts representing shares in the profits they claimed would be generated» from mining.[175]
In January 2018, Japanese exchange Coincheck reported that hackers had stolen $530M worth of cryptocurrencies.[176]
In June 2018, South Korean exchange Coinrail was hacked, losing over $37M worth of cryptos.[177] The hack worsened an already ongoing cryptocurrency selloff by an additional $42 billion.[178]
On 9 July 2018, the exchange Bancor, whose code and fundraising had been subjects of controversy, had $23.5 million in cryptocurrency stolen.[179]
A 2020 EU report found that users had lost crypto-assets worth hundreds of millions of US dollars in security breaches at exchanges and storage providers. Between 2011 and 2019, reported breaches ranged from four to twelve a year. In 2019, more than a billion dollars worth of cryptoassets was reported stolen. Stolen assets «typically find their way to illegal markets and are used to fund further criminal activity».[180]
According to a 2020 report produced by the United States Attorney General’s Cyber-Digital Task Force, the following three categories make up the majority of illicit cryptocurrency uses: «(1) financial transactions associated with the commission of crimes; (2) money laundering and the shielding of legitimate activity from tax, reporting, or other legal requirements; or (3) crimes, such as theft, directly implicating the cryptocurrency marketplace itself.» The report concludes that «for cryptocurrency to realize its truly transformative potential, it is imperative that these risks be addressed» and that «the government has legal and regulatory tools available at its disposal to confront the threats posed by cryptocurrency’s illicit uses».[181][182]
According to the UK 2020 national risk assessment—a comprehensive assessment of money laundering and terrorist financing risk in the UK—the risk of using cryptoassets such as Bitcoin for money laundering and terrorism financing is assessed as «medium» (from «low» in the previous 2017 report).[183] Legal scholars suggested that the money laundering opportunities may be more perceived than real.[184] Blockchain analysis company Chainalysis concluded that illicit activities like cybercrime, money laundering and terrorism financing made up only 0.15% of all crypto transactions conducted in 2021, representing a total of $14 billion.[185][186][187]
In December 2021, Monkey Kingdom — a NFT project based in Hong Kong lost US$1.3 million worth of cryptocurrencies via a phishing link used by the hacker.[188]
Money laundering
According to blockchain data company Chainalysis, criminals laundered US$8,600,000,000 worth of cryptocurrency in 2021, up by 30% from the previous year.[189] The data suggests that rather than managing numerous illicit havens, cybercriminals make use of a small group of purpose built centralized exchanges for sending and receiving illicit cryptocurrency. In 2021, those exchanges received 47% of funds sent by crime linked addresses.[190] Almost $2.2bn worth of cryptocurrencies was embezzled from DeFi protocols in 2021, which represents 72% of all cryptocurrency theft in 2021.
According to Bloomberg and the New York Times, Federation Tower, a two skyscraper complex in the heart of Moscow City, is home to many cryptocurrency businesses under suspicion of facilitating extensive money laundering, including accepting illicit cryptocurrency funds obtained through scams, darknet markets, and ransomware.[191] Notable businesses include Garantex, Eggchange, Cashbank, Buy-Bitcoin, Tetchange, Bitzlato, and Suex, which was sanctioned by the U.S. in 2021.
Dark money has also been flowing into Russia through a dark web marketplace called Hydra, which is powered by cryptocurrency, and enjoyed more than $1 billion in sales in 2020, according to Chainalysis.[192] The platform demands that sellers liquidate cryptocurrency only through certain regional exchanges, which has made it difficult for investigators to trace the money.
Almost 74% of ransomware revenue in 2021 — over $400 million worth of cryptocurrency — went to software strains likely affiliated with Russia, where oversight is notoriously limited.[191] However, Russians are also leaders in the benign adoption of cryptocurrencies, as the ruble is unreliable, and President Putin favours the idea of «overcoming the excessive domination of the limited number of reserve currencies.»[193]
Darknet markets
Properties of cryptocurrencies gave them popularity in applications such as a safe haven in banking crises and means of payment, which also led to the cryptocurrency use in controversial settings in the form of online black markets, such as Silk Road.[165] The original Silk Road was shut down in October 2013 and there have been two more versions in use since then. In the year following the initial shutdown of Silk Road, the number of prominent dark markets increased from four to twelve, while the amount of drug listings increased from 18,000 to 32,000.[165]
Darknet markets present challenges in regard to legality. Cryptocurrency used in dark markets are not clearly or legally classified in almost all parts of the world. In the U.S., Bitcoins are labelled as «virtual assets».[citation needed] This type of ambiguous classification puts pressure on law enforcement agencies around the world to adapt to the shifting drug trade of dark markets.[194][unreliable source?]
Wash trades
Various studies have found that crypto-trading is rife with wash trading. Wash trading is a process, illegal in some jurisdictions, involving buyers and sellers being the same person or group, and may be used to manipulate the price of a cryptocurrency or inflate volume artificially. Exchanges with higher volumes can demand higher premiums from token issuers.[195] A study from 2019 concluded that up to 80% of trades on unregulated cryptocurrency exchanges could be wash trades.[195] A 2019 report by Bitwise Asset Management claimed that 95% of all Bitcoin trading volume reported on major website CoinMarketCap had been artificially generated, and of 81 exchanges studied, only 10 provided legitimate volume figures.[196]
As a tool to evade sanctions
In 2022, cryptocurrencies attracted attention when Western nations imposed severe economic sanctions on Russia in the aftermath of its invasion of Ukraine in February. However, American sources warned in March that some crypto-transactions could potentially be used to evade economic sanctions against Russia and Belarus.[197]
In April 2022, the computer programmer Virgil Griffith received a five-year prison sentence in the US for attending a Pyongyang cryptocurrency conference, where he gave a presentation on blockchains which might be used for sanctions evasion.[198]
Impacts and analysis

Cryptocurrencies: looking beyond the hype, Hyun Song Shin, Bank for International Settlements, 2:48[199] |
The Bank for International Settlements summarized several criticisms of cryptocurrencies in Chapter V of their 2018 annual report. The criticisms include the lack of stability in their price, the high energy consumption, high and variable transactions costs, the poor security and fraud at cryptocurrency exchanges, vulnerability to debasement (from forking), and the influence of miners.[199][200][201]
Speculation, fraud, and adoption
Cryptocurrencies have been compared to Ponzi schemes, pyramid schemes[202] and economic bubbles,[203] such as housing market bubbles.[204] Howard Marks of Oaktree Capital Management stated in 2017 that digital currencies were «nothing but an unfounded fad (or perhaps even a pyramid scheme), based on a willingness to ascribe value to something that has little or none beyond what people will pay for it», and compared them to the tulip mania (1637), South Sea Bubble (1720), and dot-com bubble (1999), which all experienced profound price booms and busts.[205]
Regulators in several countries have warned against cryptocurrency and some have taken measures to dissuade users.[206] However, research in 2021 by the UK’s financial regulator suggests such warnings either went unheard, or were ignored. Fewer than one in 10 potential cryptocurrency buyers were aware of consumer warnings on the FCA website, and 12% of crypto users were not aware that their holdings were not protected by statutory compensation.[207][208] Of 1,000 respondents between the ages of eighteen and forty, almost 70% falsely assumed cryptocurrencies were regulated, 75% of younger crypto investors claimed to be driven by competition with friends and family, 58% said that social media enticed them to make high risk investments.[209] The FCA recommends making use of its warning list, which flags unauthorized financial firms.[210]
Many banks do not offer virtual currency services themselves and can refuse to do business with virtual currency companies.[211] In 2014, Gareth Murphy, a senior banking officer, suggested that the widespread adoption of cryptocurrencies may lead to too much money being obfuscated, blinding economists who would use such information to better steer the economy.[212] While traditional financial products have strong consumer protections in place, there is no intermediary with the power to limit consumer losses if Bitcoins are lost or stolen. One of the features cryptocurrency lacks in comparison to credit cards, for example, is consumer protection against fraud, such as chargebacks.
The French regulator Autorité des marchés financiers (AMF) lists 16 websites of companies that solicit investment in cryptocurrency without being authorized to do so in France.[213]
An October 2021 paper by the National Bureau of Economic Research found that Bitcoin suffers from systemic risk as the top 10,000 addresses control about one-third of all Bitcoin in circulation.[214] It’s even worse for Bitcoin miners, with 0.01% controlling 50% of the capacity. According to researcher Flipside Crypto, less than 2% of anonymous accounts control 95% of all available Bitcoin supply.[215] This is considered risky as a great deal of the market is in the hands of a few entities.
A paper by John Griffin, a finance professor at the University of Texas, and Amin Shams, a graduate student found that in 2017 the price of Bitcoin had been substantially inflated using another cryptocurrency, Tether.[216]
Roger Lowenstein, author of «Bank of America: The Epic Struggle to Create the Federal Reserve,» says in a New York Times story that FTX will face over $8 billion in claims.[217]
Non-fungible tokens
Non-fungible tokens (NFTs) are digital assets that represent art, collectibles, gaming, etc. Like crypto, their data is stored on the blockchain. NFTs are bought and traded using cryptocurrency. The Ethereum blockchain was the first place where NFTs were implemented, but now many other blockchains have created their own versions of NFTs. The popularity of NFTs has increased since 2021.[218]
Banks
As the first big Wall Street bank to embrace cryptocurrencies, Morgan Stanley announced on 17 March 2021 that they will be offering access to Bitcoin funds for their wealthy clients through three funds which enable Bitcoin ownership for investors with an aggressive risk tolerance.[219] BNY Mellon on 11 February 2021 announced that it would begin offering cryptocurrency services to its clients.[220]
On 20 April 2021,[221] Venmo added support to its platform to enable customers to buy, hold and sell cryptocurrencies.[222]
In October 2021, financial services company Mastercard announced it is working with digital asset manager Bakkt on a platform that would allow any bank or merchant on the Mastercard network to offer cryptocurrency services.[223]
Environmental impact
Mining for proof-of-work cryptocurrencies requires enormous amounts of electricity and consequently comes with a large carbon footprint due to causing greenhouse gas emissions.[224] Proof-of-work blockchains such as Bitcoin, Ethereum, Litecoin, and Monero were estimated to have added between 3 million and 15 million tonnes of carbon dioxide (CO2) to the atmosphere in the period from 1 January 2016 to 30 June 2017.[225] By November 2018, Bitcoin was estimated to have an annual energy consumption of 45.8TWh, generating 22.0 to 22.9 million tonnes of CO2, rivalling nations like Jordan and Sri Lanka.[226] By the end of 2021, Bitcoin was estimated to produce 65.4 million tonnes of CO2, as much as Greece,[227] and consume between 91 and 177 terawatt-hours annually.[228][229]
Critics have also identified a large electronic waste problem in disposing of mining rigs.[230] Mining hardware is improving at a fast rate, quickly resulting in older generations of hardware.[231]
Bitcoin is the least energy-efficient cryptocurrency, using 707.6 kilowatt-hours of electricity per transaction.[232]
The world’s second-largest cryptocurrency, Ethereum, uses 62.56 kilowatt-hours of electricity per transaction.[233] XRP is the world’s most energy efficient cryptocurrency, using 0.0079 kilowatt-hours of electricity per transaction.[234]
Although the biggest PoW blockchains consume energy on the scale of medium-sized countries, the annual power demand from proof-of-stake (PoS) blockchains is on a scale equivalent to a housing estate. The Times identified six «environmentally friendly» cryptocurrencies: Chia, IOTA, Cardano, Nano, Solarcoin and Bitgreen.[235] Academics and researchers have used various methods for estimating the energy use and energy efficiency of blockchains. A study of the six largest proof-of-stake networks in May 2021 concluded:
- Cardano has the lowest electricity use per node;
- Polkadot has the lowest electricity use overall; and
- Solana has the lowest electricity use per transaction.
In terms of annual consumption (kWh/yr), the figures were: Polkadot (70,237), Tezos (113,249), Avalanche (489,311), Algorand (512,671), Cardano (598,755) and Solana (1,967,930). This equates to Polkadot consuming 7 times the electricity of an average U.S. home, Cardano 57 homes and Solana 200 times as much. The research concluded that PoS networks consumed 0.001% the electricity of the Bitcoin network.[236] University College London researchers reached a similar conclusion.[237]
Variable renewable energy power stations could invest in Bitcoin mining to reduce curtailment, hedge electricity price risk, stabilize the grid, increase the profitability of renewable energy power stations and therefore accelerate transition to sustainable energy.[238][239][240][241][242]
Technological limitations
There are also purely technical elements to consider. For example, technological advancement in cryptocurrencies such as Bitcoin result in high up-front costs to miners in the form of specialized hardware and software.[243] Cryptocurrency transactions are normally irreversible after a number of blocks confirm the transaction. Additionally, cryptocurrency private keys can be permanently lost from local storage due to malware, data loss or the destruction of the physical media. This precludes the cryptocurrency from being spent, resulting in its effective removal from the markets.[244]
Academic studies
In September 2015, the establishment of the peer-reviewed academic journal Ledger (ISSN 2379-5980) was announced. It covers studies of cryptocurrencies and related technologies, and is published by the University of Pittsburgh.[245]
The journal encourages authors to digitally sign a file hash of submitted papers, which will then be timestamped into the Bitcoin blockchain. Authors are also asked to include a personal Bitcoin address in the first page of their papers.[246][247]
Aid agencies
A number of aid agencies have started accepting donations in cryptocurrencies, including UNICEF.[248] Christopher Fabian, principal adviser at UNICEF Innovation, said the children’s fund would uphold donor protocols, meaning that people making donations online would have to pass checks before they were allowed to deposit funds.[249][250]
However, in 2021, there was a backlash against donations in Bitcoin because of the environmental emissions it caused. Some agencies stopped accepting Bitcoin and others turned to «greener» cryptocurrencies.[251] The U.S. arm of Greenpeace stopped accepting bitcoin donations after seven years. It said: «As the amount of energy needed to run Bitcoin became clearer, this policy became no longer tenable.»[252]
In 2022, the Ukrainian government raised over US$10,000,000 worth of aid through cryptocurrency following the 2022 Russian invasion of Ukraine.[253]
Criticism
Bitcoin has been characterized as a speculative bubble by eight winners of the Nobel Memorial Prize in Economic Sciences: Paul Krugman,[254] Robert J. Shiller,[255] Joseph Stiglitz,[256] Richard Thaler,[257] James Heckman,[258] Thomas Sargent,[258] Angus Deaton,[258] and Oliver Hart;[258] and by central bank officials including Alan Greenspan,[259] Agustín Carstens,[260] Vítor Constâncio,[261] and Nout Wellink.[262]
The investors Warren Buffett and George Soros have respectively characterized it as a «mirage»[263] and a «bubble»;[264] while the business executives Jack Ma and J.P. Morgan Chase CEO Jamie Dimon have called it a «bubble»[265] and a «fraud»,[266] respectively, although Jamie Dimon later said he regretted dubbing Bitcoin a fraud.[267] BlackRock CEO Laurence D. Fink called Bitcoin an «index of money laundering».[268]
In June 2022, Bill Gates said that cryptocurrencies are «100% based on greater fool theory».[269]
In 2018, an increase in crypto-related suicides was noticed after the cryptocurrency market crashed in August. The situation was particularly critical in Korea as crypto traders were on «suicide watch». A cryptocurrency forum on Reddit even started providing suicide prevention support to affected investors.[270][271][272]
The May 2022 collapse of the Luna currency operated by Terra also led to reports of suicidal investors in crypto-related subreddits.[273]

Ее назначение – то же самое, что и обычных денег: ею можно оплатить покупку или что-то на нее продать, то есть она обладает покупательной способностью. Криптовалюту можно обменять на другие деньги – доллары, евро, рубли либо поменять одну цифровую валюту на другую (например, эфириум – на биткойн).
Крипту можно инвестировать. Это будет очень разумным решением, так как курсы самых популярных криптомонет, допустим, биткойна и эфириума, уверенно растут.
У криптовалюты много преимуществ, в отличие от привычных нам денег. Во-первых, она не боится инфляции: эту валюту нельзя напечатать на станке, так как она добывается при помощи вычисления определенных математических задач, и ее ровно столько, сколько добыли, что открыто отражается в блокчейне. Что касается биткойнов, то их количество ограниченно, и это всем пользователям заранее известно.
Во-вторых, децентрализованность обеспечивает гарантию того, что никто не сможет принудительно нарушить работоспособность этой системы или запретить. Добыча криптовалюты контролируется пользователями по всему миру, так как отсутствует общий центр с единым владельцем.
В-третьих, она обеспечена анонимностью. Конечно, транзакции отследить можно, а также увидеть, сколько валюты и какой именно перебралось из одного электронного кошелька в другой, но узнать, кто именно – владелец кошелька, непросто. Криптовалютный счёт может открыть любой человек, имеющий необходимое программное обеспечение и доступ в Сеть.
Если операции с обычными деньгами тщательно контролируются банком и легко отслеживаются, то с криптой такого нет. Информации о владельце криптовалют не требуется. В системе хранится только номер его кошелька и данные о сумме на счету.
Криптовалюта надежна. Виртуальные монеты тщательно защищены, систему невозможно взломать или обмануть.
Сейчас во многих странах разрешается приобретать авиабилеты и гаджеты, электронно-бытовую и компьютерную технику на биткойны, с их помощью оплачивают коммунальные услуги или отдых в кафе. Но в основном цифровые деньги покупают с целью заработка, инвестиций, а не для практического использования.
Криптовалютный рынок предлагает большой выбор валют, количество которых с каждым годом увеличивается благодаря тому, что цифровые деньги вызывают большой интерес не только со стороны широких слоев населения, но и крупных инвесторов, готовых вкладывать средства в стремительно развивающийся сегмент рынка. В этом главную роль сыграл успех биткоина – самой известной, популярной и востребованной криптовалюты. Все остальные валюты, запущенные после биткойна, называются альткоинами. Многие из них заслуженно считаются достаточно перспективными по причине их децентрализации и открытой технологии блокчейна.
Первая цифровая валюта – биткоин (Bitcoin, BTC), была создана в конце 2008-го – начале 2009 гг. У нее самая высокая капитализация. Биткойн – основной объект интереса со стороны инвесторов и предмет торгов на криптовалютных биржах. Его называют виртуальным золотом.
Самым раскрученным и популярным конкурентом биткоина стал Ethereum (ETH, эфириум, эфир), разработанный и запущенный российско-канадским программистом Виталиком Бутериным в середине 2015 года. Обладает высокой капитализацией, уверенно стоит на втором месте после биткойна, намного превосходя все остальные криптовалюты.
Litecoin. Эту валюту именуют виртуальным серебром. Появился в 2011 году, быстро набирая популярность и капитализацию.
Bitcoin Cash (BCash, BCC и BCH), ее запуск – с 1 августа 2018 года.
Monero. Имеет наибольший уровень анонимности платежной системы. Валюта была создана весной 2014 года.
Достаточно востребованы такие альткоины, как Dogecoin, Ripple, Cardano, XRP и многие другие.
Альткоины предлагают альтернативы майнингу, чтобы не закупать дорогостоящее оборудование, например, смарт-контракты (умные контракты).
У альткоинов есть недостатки:
- скачкообразные колебания курса;
сильная зависимость от курса биткоина (если он падает, то курсы других цифровых валют – тоже на понижении);
зависимость от решений правительств (во многих странах запрещены и майнинг, и действия с криповалютами);
- высокий риск потери доверия к цифровому активу и пр.
Капитализация и стоимость приведенных выше валют достаточно высока, но менее популярные криптовалюты значительно дешевле, тем не менее, за определённый период времени удается намайнить достаточное количество монет, получив хорошую прибыль и приумножив вложения.
Альткоины также разделили на три группы в зависимости от их особенностей:
Ø уникальные. Они обладают эксклюзивными технологиями, которых нет у биткоина. Например, Ethereum использует функцию смарт-контрактов, IOTA – с технологией направленного ациклического графа (DAG), Dash (русские пользователи называют ее Дашкой) – с возможностью передачи средств через SMS.
Стейблкоины – предназначены для хеджирования финансовых рисков, то есть компенсируют воздействие ценовых рисков равной, но противоположной позицией на другом рынке). Например, самый популярный стейблкоин Tether привязан к доллару США в соотношении 1:1, что позволяет пользователю криптовалют иметь возможность обменять имеющиеся у него альткоины на Tether, тем самым зафиксировав стоимость альткоинов в долларах США на определенную дату.
Анонимные. Это конфиденциальные криптовалюты, ориентированные на пользователей, желающих скрыть свои цифровые активы и персональные данные и сохранить в тайне информацию об их движении от отправителя к получателю, что вызывает наиболее сильную критику мировых правительств, полагающих, что такие алькоины станут инструментом для отмывания денег и финансирования терроризма.

Сегодня все говорят о том, как заработать на криптовалюте. То есть на том, чего в материальном мире даже не существует. Мир сошел с ума или мы перешли на новый этап развития? Второй вариант кажется нам более перспективным, поэтому сегодня поговорим о том, что такое криптовалюты и как ими пользоваться.
В новом обзоре эксперты сryptonisation.com расскажут просто, о том, как устроены цифровые деньги, что влияет на их ценность, как их получить и использовать. 👇
Что такое криптовалюта
Криптовалюта — это виртуальная валюта, основанная на блокчейне, которая не имеет бумажного выражения и существует только в интернете.
Сразу разберемся, что такое блокчейн и как он работает.
До появления криптовалют, чтобы перевести деньги другому человеку, нужно было обратиться к посреднику — банку. Для перевода цифровых денег посредник не нужен: криптовалюта работает на технологии Blockchain (блокчейн), которая представляет собой цепочку информационных блоков.
Блокчейн — это способ хранения информации в блоках по цепи (в переводе с англ. block+chain = цепочка блоков).
Технология работает так, что все транзакции в сети криптографически шифруются, формируют связанные между собой блоки и записываются в блокчейне. Каждая новая транзакция добавляется в конец существующей цепочки, к ней присоединяется последующая.
Запись в блокчейне нельзя ни изменить, ни перезаписать, ни создать копию. Система вычислит подобные действия и заблокирует операцию. Сети, работающие на алгоритме Proof-of-Work (PoW), поддерживаются в рабочем состоянии благодаря работе майнеров. Система использует их вычислительные мощности для генерации новых блоков и монет, и за это майнеры получают награду.

Альтернатива PoW — алгоритм Proof-of-Stake (PoS), когда валидация транзакций происходит через узлы сети. PoS (Доказательство доли владения) работает следующим образом: чем больше криптовалюты у пользователя на счете, тем у него больше шансов найти новый блок, подтвердить подлинность транзакции и получить за это вознаграждение.
Простым языком, криптовалюта — это форма денег, которые обращаются в децентрализованной (никем не контролируемой) системе.
Ни банки, ни налоговые, судебные или государственные органы не могут никаким образом воздействовать на операции с криптоактивами. Их ценность также не зависит от государства, как в случае с фиатными деньгами (именно государство запускает производство необходимого, по его мнению, количества наличных денег). Кроме того, все операции с криптовалютами необратимы: отменить или аннулировать транзакцию нельзя.
Итак, с тем, что такое блокчейн мы разобрались. Теперь давайте разбираться, зачем нужно было создавать криптовалюту. Во-первых, определим, как можно ее использовать. ✅
Криптовалюту можно применять как:
- Платежное средство (для покупки товаров и услуг);
- Инструмент для заработка (трейдинг);
- Инвестиционный актив (покупка перспективных монет с целью получения дохода в будущем или участие в управлении теми или иными проектами (по аналогии с акциями);
- Инструмент для проведения транзакций в децентрализованных финансовых сетях.
Что касается вложений в криптовалюту, то цифровые деньги вызывают большой инвестиционный интерес. Как крупные инвесторы, так и все больше простых людей вкладывают деньги в этот стремительно развивающийся сегмент рынка. И при правильном подходе вложения в криптовалюту могут принести хорошую прибыль (но не сильно расслабляемся и не забываем про возможные убытки).
История появления криптовалют
В 2009 году появилась первая цифровая монета — Биткоин. Но технология, на которой он построен, имеет еще более глубокие корни. Еще ранее предпринимались попытки создания цифровой валют с реестрами, защищенными шифрованием. В качестве примера можно привести такие проекты, как B-Money и Bit Gold, механизм работы которых был полностью описан, но так и не разработан.
В 2008 году в сети впервые появилась информация про Биткоин. Кто-то по имени Сатоши Накамото, личность которого до сих пор остается нераскрытой, опубликовал документ под названием “Биткойн — одноранговая электронная денежная система”.
Документ был размещен в списке рассылки, посвященном обсуждению криптографии. А в 2009 году состоялся официальный запуск первой криптовалюты Биткоин: 3 января был сгенерирован первый блок и первые 50 BTC-монет, первая транзакция в сети произошла 12 января. Тогда же и начинается майнинг — процесс добычи новых биткоинов.
По мере того, как идея децентрализованных и зашифрованных валют становится все более популярной, появляются первые альтернативные криптовалюты (альткоины). Они, как правило, копируют основную идею, вложенную в Биткоин, но пытаются его улучшить, предлагая большую скорость, анонимность и другие преимущества. Первыми альткоинами стали Namecoin и Litecoin, которые появились в 2011 году.
В 2013 году цена Биткоина достигла $1000, но очень быстро обвалилась до $300, и потребовалось более 2 лет, чтобы курс снова нагнал отметку в тысячу долларов. Между тем, в 2014 году произошло первое мошенничество, связанное с криптовалютой. В январе 2014 года крупнейшая на тот момент биткоин-биржа Mt.Gox внезапно закрылась и владельцы 850 000 BTC больше никогда не видели свои деньги (ущерб оценивается в $450 млн).
В 2015 году появился Эфириум, запуск которого принес в индустрию много нового, а именно смарт-контракты и первичное предложение монет (ICO). Энтузиазм вокруг платформы рос, и в 2016 году монета была близка к тому, чтобы украсть первенство у Биткоина.
Однако, в 2017 году Биткоин достигает рекордной отметки в $10 000 и продолжает расти. Этому способствовало постепенное увеличение количества мест, где можно было расплатиться биткоином, а также новая волна хайпа вокруг цифровых валют. В экосистему поступало все больше денег, рыночная капитализация всех криптовалют сильно выросла. В криптовалюту стали вкладываться международные банки и организации, и в индустрии финансовых технологий началась новая цифровая эра.
Однако, период стремительного роста сменился крахом. Это событие ознаменовали Великим криптокрахом 2018: в первом квартале года большинство криптовалют значительно упали в цене. Так, например, всего за месяц (с 6 января по 6 февраля 2018) Биткоин подешевел на 65%. Таким образом, 2018 год прошел в режиме панихиды по биткоину и рынку криптовалют в целом.
2019 год стал своего рода годом трансформаций для криптовалютной индустрии, которая из подпольного бизнеса превратилась в неотъемлемую часть мировой финансовой системы. Весной криптовалюты начали показывать многократный рост, и в лидеры роста выбился Binance Coin, внутренний токен топовой по капитализации биржи Binance. Отличные результаты также показали Litecoin, Tezor, EOS.
Таким образом, криптовалюта стала постепенно интегрироваться в мировую финансовую систему и получать все большее распространение.
2020 год стал началом нового цикла роста криптовалют. В них начали активно вкладываться миллиардеры и крупные институциональные инвесторы. Одним из драйверов роста стоимости приктовалют стал халвинг биткоина, который произошел в мае 2020. Тогда награда, которую получают майнеры за добычу монеты, снизилась с 12,5 до 6,25 BTC. И в целом, несмотря на разрастание масштабов пандемии коронавируса, 2020 год стал годом роста криптовалют.
В 2021 году оценка крипторынка выросла почти на 200%, достигнув значения около $2,3 трлн. В этом году был также зафиксирован исторический максимум стоимости Биткоина, превысивший $65 000 за одну монету.
Как видим, Биткоин и другие криптовалюты не были стабильными на протяжении большей части своей истории. Первая криптовалюта по-прежнему является самой главной: Биткоин “правит балом” и стоит дороже других монет. Однако, некоторые альткоины за прошедший год подорожали на тысячи и даже десятки тысяч %, благодаря чему попали в ТОП по капитализации и в нем закрепились. По мнению экспертов, в 2023 году многие перспективные альткоины укрепят свои позиции и попытаются сместить Биткоин с главного места на пьедестале. 🔥

Говоря про любые деньги, в первую очередь имеют в виду их полезность. И фиатные деньги, и криптовалюта являются эффективной формой денег: они могут выступать в качестве средства обмена, расчетной единицы или средства сбережения.
Однако, они отличаются по ряду ключевых моментов. Если вкратце, то фиатные деньги — это законное платежное средство, выпуск и обращение которого контролируется государством. Распределение фиата также предполагает наличие посредников.
Криптовалюта — это форма денег, которая существует в цифровой децентрализованной (никем не контролируемой) среде и стоимость которой также не зависит от государства. Криптовалютой управляет само сообщество, а ее ценность формируется за счет спроса и предложения.
У цифровой валюты еще много преимуществ перед традиционными деньгами. Но есть и свои слабые стороны. Мы собрали все основные плюсы и минусы криптовалют в одной таблице. 👇
Децентрализация и отсутствие контроля за сетью;
Доступность;
Созданы на базе полностью прозрачной технологии блокчейн;
Разные способы применение: платежное средство, актив для инвестиций, инструмент для заработка (трейдинг, майнинг, стекинг и др);
Могут быть потрачены и получены кем угодно, где угодно и в любое время без необходимости в посреднике;
Конфиденциальность;
Низкие транзакционные издержки;
Высокая скорость обработки платежей;
Неподверженность инфляции;
Стимул для инноваций в традиционной финансовой сфере.
Крайне высокая волатильность;
Проблема масштабируемости;
Ограниченное применение: не принимаются в качестве оплаты в большинстве магазинов;
Отсутствие массового признания;
Сложность использования для повседневных транзакций;
Отсутствие легитимности;
Успешные хакерские атаки и хищение средств;
Использование в преступных целях;
Риск теоретической “атаки 51%”.
Криптовалюты в сравнении с фиатными деньгами
Криптовалюты имеют много общего с обычными фиатными деньгами. И те, и другие могут использоваться для платежей и в качестве средства сбережения. В обоих случаях, чтобы функционировать как средство обмена, требуется доверие со стороны пользователей.
Однако, цифровые деньги предлагают функции, которые традиционная денежная система сейчас не может предложить (почему криптовалюту и называют “валютой будущего”). И в первую очередь имеется в виду их децентрализация: криптовалюта не контролируется ни государством, ни каким-либо централизованным органом, позволяя осуществлять прямые транзакции без вмешательства посредников. В отличие от фиата, который находится полностью под управлением банков и правительств.
Под фиатом подразумевают товарные деньги, которые получают свою ценность от того, что правительство объявляет их законным платежным средством (внутренней ценности они не имеют).
Таким образом, если криптовалюту может получать и тратить и кто угодно, где угодно, в какое угодно время по всему миру и без необходимости в банке или правительстве, то фиатные деньги находятся под контролем государства. И центральный банк может выпускать столько банкнот и монет, сколько посчитает нужным.
Таким образом, Биткоин, как первая криптовалюта, создал новую форму доверия к финансовой системе. Система, лежащая в основе цифровых денег, полностью прозрачна, основана на математике и фактическом согласии пользователей.
Фиатная валюта по-прежнему остается доминирующей формой денег, но криптовалюты представляют собой следующий шаг в их эволюции.
Формы криптовалют
Цифровую валюту делят на коины и токены. Некоторые отождествляют эти два понятия, что является заблуждением. Разберемся, чем коины отличаются от токенов (это важно).
Коин — денежная единица криптовалютного проекта, функционирующая на собственном блокчейне. Коины добывают с помощью майнинга. Их можно легко переводить другим пользователям системы, оплачивать товары и услуги, а также продавать за фиатные валюты.
Все коины, кроме биткоина, называются 👉 альткоинами.
Токен — денежная единица криптовалютного проекта, которая работает на основе существующего блокчейна. Добыть токены нельзя: только купить или получить в качестве вознаграждения за ту или иную активность.
Расплачиваться токенами за товары или услуги нельзя: их основная функция — открыть доступ к функциям криптовалютной платформы. Токены также используются как инструмент для инвестиций, с их помощью можно принимать участие в голосованиях или опросах. Токены можно обменять на обычные деньги или другую криптовалюту, но для этого их нужно вывести на биржу. В отличие от коинов, функционирующих на блокчейне Биткоина, большинство токенов работают на блокчейне Ethereum.
Простыми словами, если проводить аналогию с реальной жизнью, то коины можно сравнить с денежными купюрами или монетами, а токены — с пропускным билетом, открывающим те или иные возможности.
Виды криптовалют
Все существующие цифровые активы выпускают с той или иной целью. Выделяют 7 основных типов криптовалют: платежные криптовалюты, платформенные токены, биржевые токены, стейблкоины, служебные коины, токены-аналоги ценных бумаг, крипто-товары. 👇
Currencies Coins
Основное предназначение платежных криптовалют — оплата товаров и услуг. Их отличает децентрализация, простота использования и высокий уровень анонимности. Кроме того, такие платежные инструменты могут служить объектом инвестиций. Самым ярким и наглядным примером Currencies Coin является Биткоин.
Platforms Coins
Токены криптовалютных платформ используются для разработки и выполнения смарт-контрактов (контракты, контролирующие автоматическую передачу активов между сторонами договора на определенных условиях). Platforms Coins также широко используются в качестве платежного средства. Самая популярная платформенная криптомонета — Ethereum.
Cryptocurrency Exchanges
Все крупные торговые площадки выпускают собственные цифровые токены, которые являются своего рода “топливом” для их работы. Благодаря выпуску внутренних токенов ускоряется оборот средств на бирже и повышается ликвидность.
Биржевые токены используются также для покупки других цифровых активов и дают скидку при оплате торговых комиссий.
Такие монеты отличает хорошая ликвидность, но ровно до тех пор, пока выпустившая их платформа имеет успех. Если криптобиржа теряет популярность, то ее биржевые токены также становятся непривлекательными для трейдеров и инвесторов. Примеры биржевых токенов — Binance Coin, EXMO и другие. 🚩
Stable Coins
Стоимость стабильных коинов привязана к какому-то физическому активу (золоту, фиатной валюте и тд), поэтому они не так волатильны, как другие цифровые валюты. С другой стороны, стейблкоины обеспечиваются национальными деньгами, выпуск которых полностью централизован. Самым известной монетой этого типа является Tether (USDT), который равен $1. Компания Tether Limited, выпускающая стейблкоин, утверждает, что стоимость USDT на 20% обеспечивается хранящимися на ее счетах долларами США.
Utility Tokens
К этому типу относятся так называемые служебные коины.Они служат для проведения ICO (Initial Coin Offerings/первичный выпуск монет) и выпускаются в ограниченном объеме. Как правило, после завершения кампании по сбору средств такие токены могут продвигаться в качестве инвестиционного инструмента. Хороший пример служебного токена — Siacoin.
Его основная миссия которого — позволить использовать децентрализованную сеть облачного хранилища Sia.
Security Tokens
Security Tokens (STO) — это прямая аналогия ценных бумаг. Они распределяются среди вкладчиков, что позволяет усилить безопасность инвестиций. Право владения такими токенами фиксируется в смарт-контрактах. Таким образом, STO являются чем-то вроде маркера, который получает каждый инвестор. Такие токены продаются на торговых площадках, на их основе распределяются выплаты дивидендов вкладчикам, их можно вкладывать в другие криптопроекты.
В качестве примера приведем токенизированное право на майнинг биткоина на конкретном оборудовании и с определенной мощностью, которое запустили в Blockstream. По их условиям, намайненные биткоины будут отданы владельцам через 36 месяцев.
Crypto Commodities
Крипто-товары — это общее название продаваемых или обменных активов, которые можно получить через блокчейн-сеть. Их используют для оплаты товаров и услуг в рамках конкретной платформы. Такие токены отличает саморегулирование и автоматическое выполнение финансовых операций, что заложено в программном коде в виде смарт-контракта.
Crypto Commodities никогда не используются за пределами конкретного проекта. В качестве примера крипто-товара можно привести внутреннюю валюту браузера Brave, которая используется для оплаты рекламы и создания контента.
10 лучших криптовалют в 2023 году
Вслед за Биткоином, рынок криптовалют стал активно наполняться другими криптовалютами (альткоинами) . Однако, среди них полно тех, которые не имеют какой-либо технологической ценности и заметной цели. В криптосообществе такие монеты называют “шиткоинами”.
Шиткоин (от англ. shit + coin) – жаргонное выражение в среде криптосообщества, которое закрепилось за криптовалютами, не представляющими особого интереса для инвесторов и трейдеров.
Другое дело – монеты из топа, по которым ведутся активные торги, которые уже признаны и приняты криптосообществом. ТОП-10 лучших криптовалют в 2023 году возглавляет Биткоин, за ним идут Эфириум, Лайткоин, Кардано и другие. Разберем подробнее каждую монету и ее особенности.

Почему криптовалют так много
По данным сайта маркетинговых исследований CoinMarketCap.com, в декабре 2021 года для публичных торгов были доступны около 16 000 различных криптовалют. Общая стоимость всех цифровых денег перевалила за $2 триллиона. Однако, далеко не все монеты достойны внимания.
Среди них много так называемых “шиткоинов”,чья инвестиционная ценность довольно сомнительна.
Для того, чтобы молодой криптопроект привлек внимание сообщества, требуется не только новизна идеи, но и правильная команда, грамотная маркетинговая политика, поддержка от крупных инвесторов и тд.
Сегодня более перспективными считаются технологичные криптовалюты, имеющие практическое применение. И это число точно меньше 16 000, торгующихся на рынке.
Что влияет на курс криптовалют
Цена той или иной цифровой валюты зависит от множества фундаментальных и технических факторов. Существуют триггеры, способные вызвать постепенный или резкий рост цены криптовалют или ее обвал. Так, любое раскрытие важной информации о монете приводит к скачку роста ее стоимости.
Среди триггеров, вызывающих наибольшее влияние на курс криптовалюты в краткосрочной перспективе, служат заявления о существенных улучшениях проекта, различных слияниях и поглощениях. В долгосрочной перспективе — новости о добавлении новых функций, например, внедрение стекинга, заключении партнерства с видными игроками рынка, халвинг и тд.
Что касается фундаментальных характеристик, то они также оказывают сильное влияние на курс монеты. Техническая составляющая блокчейна, его особенности и способность к масштабируемости влияют на производительность сети, количество майнеров, что напрямую сказывается на востребованности и распространенности актива.
Если техническая составляющая криптопроекта слабая или обнаруживаются сетевые угрозы, то настроение рынка к нему сразу меняется.
Также влияние на курс актива оказывают действия крупных игроков и регуляция. Например, крупный инвестор заявил о намерении приобрести монету Х в крупных количествах — интерес к ней сразу повышается. Другой пример ― обнародование позиции Народного Банка Китая по криптовалюте, подразумевающей ее запрет в качестве средства платежа, обвалило курсы Биткоина и Эфириума до рекордных в 2021 году отметок. Поэтому на курс цифровой валюты также влияет регуляция. 🔥
Таким образом, среди триггеров, оказывающих влияние на курс актива, выделяют:
- Раскрытие важной информации о проекте: получение финансирования, заключение партнерства, добавление в листинг на крупных биржах, добавление стекинга, халвинг, сжигание монет и тд;
- Техническая ценность проекта, функционирование блокчейна и тд;
- Популярность и общая рыночная капитализация;
- Регуляция;
- Способы применения в реальной жизни как средства платежа и накопления;
- Поведение крупных игроков рынка, новости, прогнозы экспертов;
- Регуляция и статус криптовалюты.
Как получить криптовалюту
Покупка криптовалюты
Многие пользователи, начинающие погружаться в криптоиндустрию, ошибочно считают, что криптовалюту сложно достать. 👇
Представляете: ее можно просто взять и купить за евро и другие фиатные деньги. А покупку оплатить картой Visa/Mastercard, банковским переводом и тд. Обмен произойдет мгновенно и вуаля — монетки в вашем криптокошельке.
Для покупки криптовалюты существуют различные сервисы, где продавцы продают, а покупатели покупают цифровые монеты за другую криптовалюту или за фиатную валюту. Самые популярные способы покупки криптовалюты — биржи и обменники. Первый способ более выгодный и надежный, второй — простой и быстрый. Альтернатива без посредника — p2p-обменники, которые позволяют пользователям совершать сделки покупки/продажи криптовалюты напрямую друг с другом.
Майнинг
Майнингом называется процесс создания нового блока в сети, которым занимаются майнеры. Они предоставляют системе вычислительные мощности своего оборудования, за что получают вознаграждение в виде криптомонет. Однако, сложность майнинга постоянно растет, и если в начале появления криптовалют майнить можно было с обычного ПК, то теперь для майнинга необходимо привлекать огромные вычислительные мощности.
Таким образом, многие способы майнинга стали неэффективными.
Майнеры начали придумывать новые варианты, как зарабатывать на добыче криптомонет, и так появились майнинговые фермы (майнеры объединяю мощности своих компьютеров, чтобы увеличить шансы на успех).
Облачный майнинг
Добывать криптовалюту можно облачным способом, то есть брать вычислительные мощности в аренду. Существует множество сервисов, предлагающих пользователям такие услуги. Вы заключаете облачный контракт с одним из них, предварительно изучив различные предложения, и покупаете мощности на определенную сумму. Чем больше вы вложили, тем больше сможете заработать.
Стейкинг
Доходность майнинга зависит возможностей задействованной техники: чем больше суммарная мощность, тем выше шансы добыть блок первым. Но существует другой способ заработка на криптовалюте — стейкинг, где ключевую роль играет количество имеющихся у пользователя монет. Они размещаются на специальном счете и используются для обслуживания блокчейна, а владелец активов получает за это вознаграждение.
Фарминг
Фарминг, или доходное фермерство, становится одним из самых популярных пассивных способов заработка в индустрии DeFi. Он заключается в предоставлении ликвидности проекту путем размещения токенов в пуле. Взамен пользователи получают вознаграждение в зависимости от вложенной ими суммы.
Простыми словами, фарминг — это получение прибыли за размещение токенов на бирже криптовалют. Подробнее про доходное фермерство читайте в статье.
Трейдинг
Такой вид заработка, как крипторейдинг, основан на принципе “Купи дешевле и продай дороже”. Ввиду того, что цена криптовалют постоянно меняется, трейдер может заключать быстрые сделки и зарабатывать на разнице курсов. Торговля криптовалютой проходит на торговых площадках — криптобиржах.
Далее внести на биржу депозит и покупать крипту за другие цифровые валюты или за фиатные (если биржа работает с фиатом). Популярные биржи для трейдинга 👉 Binance, OKX (OKEX), Exmo.
Покупаем криптовалюту правильно
Переходим к непосредственной покупке криптовалюты. Где и как ее лучше покупать?
За последние несколько лет крипторынок вырос многократно. Однако, начинающим инвесторам нужно быть готовым заходя на этот рынок, потому что он сильно отличается от сферы традиционных финансов.
Важно разбираться, какие способы для купли/продажи криптовалюты существуют. Выбор надежного партнера поможет снизить риски и повысить шансы на успех.
Где покупаем
Основными вариантами для покупки криптовалюты являются:
- Онлайн-обменники: самый простой и быстрый способ приобрести криптовалюту, который подойдет новичкам; доступны все самые популярные монеты; для оплаты доступны разные способы (банковский перевод, банковские карты, платежные системы и тд); курс покупки устанавливается самим сервисом на основании данных основных бирж (не всегда самый выгодный); размер комиссии зависит от криптовалюты, способа оплаты и конкретного обменника; Определиться с самым выгодным курсом помогут агрегаторы обменников, такие как 👉 Bestchange.ru.
- Криптобиржи: самый надежный способ покупки криптовалюты; нужно пройти регистрацию и часто требуется верификация (прохождение процедуры KYC и AML); простой ввод, как правило, без комиссий; курс более выгодный, чем в обменниках; покупка криптовалюты за фиат, оплата картами Visa/Mastercard; высокий уровень безопасности.
- P2P-площадки (person to person — “от человека к человеку”): прямые сделки купли/продажи криптовалюты между пользователями, без посредников в виде бирж или обменников; сервисы выступает в качестве гаранта сделки; пользователь может выбрать вариант с подходящим для себя курсом; использование эскроу-счетов (удержание средств до тех пор, пока не пройдет транзакция); для вывода средств потребуется пройти верификацию; самой популярной p2p-платформой является LocalBitcoins. 🚩
- Криптоматы: работают по аналогии с банкоматами; простые в использовании: нужно ввести адрес, на которой поступит криптовалюта, и внести средства; достаточно высокие комиссии (от 5% и выше); невысокая распространенность данных устройств;
- Telegram-боты: покупка монет прямо из мессенджера (не нужно изучать, как работаю биржи и обменники); отсутствие регистрации, анонимные сделки, экономия времени за счет полностью автоматизированных процессов покупки/продажи (через команды боту).
Как покупаем
На примере топовой биржи 👉 Binance рассмотрим основные этапы покупки криптовалюты через биржу.
Во-первых, отметим, что биржа позволяет приобрести криптовалюту несколькими способами:
- С помощью банковской карты;
- Через фиатный баланс на Бинансе;
- Напрямую в биржевом терминале;
- Через P2P-платформу;
- С помощью партнеров (Simplex, Mercuryo).
Но чтобы получить доступ к этим функциям, сначала необходимо зарегистрироваться на бирже. Бинансе также ввела обязательную верификацию для всех новых пользователей.
Смотрите инструкцию, как пройти регистрацию и верификацию на Бинансе.
После создания и верификации аккаунта на бирже, можно переходить к пополнению счета. Торговая платформа поддерживает фиат, поэтому завести на биржу можно доллары, евро и другие фиатные деньги:
- Для пополнения с банковской карты Visa/Mastercard: в личном кабинете выбираем Купить криптовалюту → Пополнение с карты;
Пополнение Binance-аккаунта с карты - Для пополнения через платежные системы доступны 2 опции: Пополнить баланс счета Advcash или Пополнить баланс счета Payeer.
Внесение депозита через платежные системы
Зачисленные на биржевой счет средства можно использовать для покупки криптовалюты. Для начала выбираете, какой из доступных способов вам подходит, и выполняете определенные действия. Например, для покупки монет непосредственно через торговый терминал биржи:
- В личном кабинете выбираем вкладку Торговля → Классическая;
- Выбираем торговую пару, например, BTC/USDT;
- Определяем тип ордера для сделки;
- Создаем ордер на покупку: указываем количество, цену и другие необходимые данные (в зависимости от выбранного ордера);

Как правильно инвестировать в криптовалюты
Перед тем, как инвестировать в криптовалюты, важно понимать, что никто не даст гарантий того, что вы получите прибыль. Вероятность получить убытки очень высокая. Кроме того, существует прямая зависимость уровня рискованности от доходности актива: чем больше потенциальная прибыль, тем выше риски.
Чтобы минимизировать риски инвестиций в криптовалюту, эксперты советуют разбить капитал на 3 портфеля:
- Безопасный: инвестиции в очень стабильные и надежные активы (насколько понятие “стабильность” может быть отнесено к криптовалютам);
- Среднерисковый: инвестиции в надежные и перспективные активы, предполагающие средний уровень доходности и рисков;
- Высокорисковый: спекулятивные инвестиции, предполагающие высокий риск и такую же высокую потенциальную прибыль.
Помимо этого, помните, что инвестировать (в криптовалюту или любой другой актив) нужно только те средства, которыми вы готовы рискнуть и даже потерять. Также следует быть готовым к тому, что в первые несколько лет, скорее всего, не избежать больших просадок в силу высокой волатильности криптовалют (бывают дни, когда рынок садится и на 20%-30%). Нужно иметь четкую стратегию и план, чтобы не нервничать при каждом неизбежном движении. А также поставить конкретную инвестиционную цель: сколько и за какой период вы хотите заработать.
На рынке криптовалют нужно вести себя очень осторожно и изначально относиться к данным инвестициям как к высокорискованным.
Риски связанные с криптовалютами
Считать криптовалюту инструментом для безопасных инвестиций — опрометчиво. Это очень спекулятивный инструмент, с очень высокой волатильностью, и движения курса за день могут съесть до 15–20% инвестиций.
Кроме крайне высокой волатильности, риски вложений в крипту связаны с ее возможным обесцениванием.
И это одна из самых обсуждаемых тем среди людей, заходящих на рынок криптовалют. Так, в истории уже были моменты, когда цена Биткоина опускалась практически до нулевого значения. И пусть это произошло из-за сбоя в системе, кто даст гарантию, что не произойдет в гораздо больших масштабах? 🔥
Опасность использования криптовалюты заключается и в том, что если утратить ключ к своему кошельку, то доступ к его содержимому также будет потерян. И тут ни банк, ни полиция вам не помогут. А если наткнуться на недобросовестный сервис, то ваши средства достанутся мошенникам. Ну или хакеры сами до них доберутся. Поэтому о защите своего цифрового капитала нужно думать в первую очередь.
Легальны ли криптовалюты
Растущий рынок криптовалют привлекает все больше внимания регулирующих органов. Действия правительств, Центральных банков и других органов власти напрямую влияют на актуальную ситуацию на рынке и перспективы массового принятия криптовалют в целом.
Создается все больше законов и актов, касающихся цифровых активов, определяющих их статус в той или иной стране.
Впервые Биткоин был признан официальной валютой в Сальвадоре в 2020 году, и это пока единственный случай. Разные страны предпринимают те или иные шаги по легализации или, наоборот, запрету использования криптовалют. Например, США постепенно двигаются в сторону легализации, тогда как Китай — запретил майнинг и торговлю цифровыми активами.
Одной из громких тем последних лет стал вопрос создания национальных криптовалют. Многие мировые ЦБ заявили о том, что готовятся к запуску своей цифровой валюты. Первая национальная криптовалюта появилась в Венесуэле в 2018 году: обеспеченная нефтью криптовалюта El Petro.
Криптовалюта в России
1 января 2021 года в силу вступил закон “О финансовых цифровых активах”. 🚩
Cогласно новому законопроекту, цифровые активы признаются имуществом, а значит ― могут быть объектом залога, сделок купли-продажи и обмена. Но они не признаются средством платежа. Чтобы проводить сделки с криптовалютой, российские банки и биржи должны быть включены в специальный реестр ЦБ. Кроме того, сделки с цифровой валютой, задекларированные в России, можно оспаривать в суде.
По словам экспертом, “закон может сократить некоторые частицы “теневого” рынка, например число обменных пунктов криптовалют”.
Однако, данный законодательный акт объективно нуждается в доработке. Он не затронул ряд фундаментальных вопросов, таких как майнинг или функционирование криптобирж. Установлены жесткие ограничения для лиц, выпускающих цифровые валюты, тогда как Центральный Банк получит дополнительные полномочия.

FAQ
Что такое криптовалюта простыми словами?
Криптовалюта – это цифровая валюта, которая функционирует в децентрализованной среде, без участия банков и других контролирующих органов. Создается и передается с помощью криптографических методов, преимущественно на базе технологии блокчейн.
В чем смысл криптовалют?
Операции с криптовалютами конфиденциальны, защищены криптографически и не требуют участия посредников.
Как работает криптовалюта?
Криптовалюта функционирует в децентрализованной платежной среде. Она представляет собой записи о транзакциях, которые хранятся на компьютерах (узлах) по всему миру. Данные записи защищены криптографическими ключами (публичный + приватный), и чтобы получить доступ к содержимому записи, нужно владеть обоими ключами. Все операции с участием криптовалют записываются в блоки и объединяются в цепочку блоков — блокчейн.
Зачем нужна криптовалюта?
С появлением криптовалют пользователи получили возможность получать, пересылать и тратить деньги анонимно, без посредников и контроля со стороны банка или другого органа.
Какая есть криптовалюта?
Самая первая криптовалюта была создана в начале 2009 года. Она получила название Bitcoin (от англ. bit — бит и coin — монета). Все криптовалюты, которые стали появляться после Биткоина, называются альткоинами. Наиболее популярные альткоины – Ethereum, Litecoin, Dogecoin, Tron, Cardano и другие. В целом, количество альткоинов уже исчисляется десятками тысяч, и этот список продолжает расти.
Чем удобна криптовалюта?
Криптовалюта позволяет отправлять анонимные, быстрые и дешевые платежи в любую точку мира. Криптовалюта также не подвержена инфляции.
Как пользоваться криптовалютой?
В зависимости от потребностей пользователя, можно использовать “холодные” кошельки (не подключены к сети, обеспечивают более высокий уровень надежности и подходят для долгосрочного хранения), а также “горячие” кошельки (все время подключены к сети, обеспечивают быстрый доступ к средствам и подходят для активной торговли и ежедневного использования).
Как создается криптовалюта?
В отличие от традиционных денег, которые выпускаются государством, у криптовалюты нет единого эмитента. Новые криптомонеты создаются либо в процессе майнинга, либо в процессе форжинга.
Майнинг – этот процесс, при котором вычислительные мощности компьютеров используются для решения сложных математических задач, в результате чего генерируются новые блоки в блокчейне (алгоритм PoW). Данный процесс предполагает использование большого количества электроэнергии, поэтому более энергоэффективной альтернативой майнингу является форжинг. Это процесс создания новых блоков на основании подтверждения доли владения (алгоритм PoS). Сегодня большинство новых криптовалют создаются путем форжинга и работают на алгоритме PoS.
Какие функции денег выполняет криптовалюта?
Криптовалюта выполняет следующие основные функции денег: средство платежа, мера стоимости, средство обращения, средство накопления.
Почему криптовалюта имеет ценность?
Криптовалюта имеет ценность, т.к. обладает рядом свойств, присущих традиционным деньгам. Одним из таких важных свойств является полезность: пользователи криптовалют могут быстро и анонимно переводить активы по всему миру без посредников.
Также стоит сказать о таком свойстве криптовалют, как коллективное доверие. Например, пользователи покупают биткоины, видя, что другие тоже инвестируют в BTC, или используют биткоины как платежное средство за товары и услуги.
Такие свойства цифровых денег как децентрализация, дефицит предложения и безопасность также создают их ценность.
Чем обеспечена криптовалюта?
Ничем. Курс той или иной криптовалюты зависит только от баланса спроса и предложения на рынке.
Заключение
Все больше людей начинают интересоваться криптовалютами и пользоваться ими в повседневной жизни. А мировые Центробанки все чаще поднимают вопрос о создании национальных криптовалют. Ждет ли цифровые деньги массовое признание и смогут ли они заменить фиат?
Мнение пользователей относительно перспективности цифровых денег по-прежнему разное. Одни считают криптовалюту “валютой будущего”, а другие оперируют тем, что она нуждается в стабильности.
Ведь если задуматься, то криптовалюта — это виртуальные деньги, используемые только в интернете. И многим до сих пор сложно вообразить, как то, чего не существует в материальном мире, может стоит десятки тысяч долларов.Однако, у криптовалюты есть масса преимуществ перед обычными деньгами, что дает ей право претендовать на роль официального платежного средства.
Но государствам это невыгодно: они не имеют никакого контроля над криптовалютными денежными потоками, и не могут на него влиять.
Однако, после появления криптовалют финансовый мир уже никогда не будет прежним. И все это понимают. 😉
Я не думаю, а действую: в моем инвесторском портфеле помимо биткоина есть несколько других перспективных криптовалют.
