A cryptocurrency exchange , or a digital currency exchange ( DCE ), is a business that allows customers to trade cryptocurrencies or digital currencies for other assets, such as conventional fiat money or other digital currencies. Exchanges may accept credit card payments, wire transfers or other forms of payment in exchange for digital currencies or cryptocurrencies. A cryptocurrency exchange can be a market maker that typically takes the bid–ask spreads as a transaction commission for its service or, as a matching platform, simply charges fees.
49-504: BitMEX is a cryptocurrency exchange and derivative trading platform. It is owned and operated by HDR Global Trading Limited, which is registered in the Seychelles . BitMEX offers a variety of cryptocurrency-based financial products, including perpetual contracts, futures contracts, and options contracts. These products allow traders to bet on the price movements of cryptocurrencies like Bitcoin, Ethereum, and others, without actually owning
98-630: A Decentralized Autonomous Organization , is done through tokens that grant voting rights and are distributed amongst participants. However, the majority of these tokens are often held by few individuals and are rarely used to vote. In July 2018, the decentralized exchange Bancor was reportedly hacked and suffered a loss of $ 13.5M in assets before freezing funds. In a Tweet, Charlie Lee , the creator of Litecoin spoke out and claimed an exchange cannot be decentralized if it can lose or freeze customer funds. Operators of decentralized exchanges can face legal consequences from government regulators. One example
147-584: A decentralized and autonomous manner. In June 2020, Compound Finance, a decentralized finance protocol enabling users to lend or borrow cryptocurrency assets and which provides typical interest payments to lenders, started rewarding lenders and borrowers with a cryptocurrency called Comp. This token, which is used for running Compound, can also be traded on cryptocurrency exchanges . Other platforms followed suit, leading to stacked investment opportunities known as "yield farming" or "liquidity mining", where speculators shift cryptocurrency assets between pools in
196-489: A centralized intermediary such as a cryptocurrency exchange or a traditional securities exchange, transactions are directly made between participants, mediated by smart contract programs. These smart contracts, or DeFi protocols, typically run using open-source software that is built and maintained by a community of developers. DApps are typically accessed through a browser extension or application. For example, MetaMask allows users to directly interact with Ethereum through
245-447: A common challenge in DeFi. Decentralized exchanges (abbreviated DEXs) are alternative payment ecosystems that use new protocols for financial transactions. They emerged within decentralized finance (DeFi), a sector of blockchain technology and fintech . Centralized exchanges (CEXs), DEXs and DEX aggregators are all built on a multi-layered DeFi architecture, with each layer serving
294-399: A digital wallet. Many of these DApps can be linked to create complex financial services. For example, stablecoin holders can lend assets such as USD Coin or DAI to a liquidity pool in a borrow/lending protocol such as Aave Protocol, and allow others to borrow those digital assets by depositing their own collateral. The protocol automatically adjusts interest rates based on the demand for
343-579: A lack of KYC processes, and no way to revert a transaction, users are at a loss if they are ever hacked for their passwords or private keys. Additionally, liquidity providers staking in DeFi protocols can suffer what is called an impermanent loss if, when withdrawn, the token pairs they have invested have altered in value ratio significantly. Although liquidity pool DEX are the most widely used, they may have some drawbacks. The most common problems of liquidity pool DEXes are market price impact , slippage , and front running . Price impact occurs because of
392-471: A platform and between platforms to maximize their total yield , which includes not only interest and fees but also the value of additional tokens received as rewards. In July 2020, The Washington Post described decentralized finance techniques and the risks involved. In September 2020, Bloomberg said that DeFi made up two-thirds of the cryptocurrency market in terms of price changes and that DeFi collateral levels had reached $ 9 billion. Ethereum saw
441-548: A programmable, permissionless blockchain . This approach reduces the need for intermediaries such as brokerages , exchanges , or banks . DeFi platforms enable users to lend or borrow funds, speculate on asset price movements using derivatives , trade cryptocurrencies , insure against risks, and earn interest in savings-like accounts. The DeFi ecosystem is built on a layered architecture and highly composable building blocks. While some applications offer high interest rates , they carry high risks. Coding errors and hacks are
490-537: A report written for the United Nations Office on Drugs and Crime . A common approach to cyber money laundering was to use a digital currency exchanger service which converted dollars into Liberty Reserve and could be sent and received anonymously. The receiver could convert the Liberty Reserve currency back into cash for a small fee. In May 2013, digital currency exchanger Liberty Reserve was shut down after
539-494: A rise in developers during 2020 due to the increased interest in DeFi. DeFi has attracted venture capitalists such as Andreessen Horowitz and Michael Novogratz . The Economist regarded the future of digital finance in 2022 as a "three-way fight" between: Big Tech , such as Facebook with its digital wallet; "big rich countries" that have been testing their own digital currencies; and software developers "building all sorts of applications" to decentralize finance. Handling

#1732894366277588-408: A slippage tolerance option for end-users. This option serves as a safeguard, allowing users to set a limit on the worst acceptable price they are willing to accept from the time of transaction signing. A decentralized exchange can still have centralized components, whereby some control of the exchange is still in the hands of a central authority. The governance of a DeFi platform, typically as part of
637-450: A survey by Encrybit to understand cryptocurrency exchange problems. According to the survey, the top three cryptocurrency exchanges are: Other data points in the survey included the problems that cryptocurrency traders experience with cryptocurrency exchanges and the expectation of traders. Security and high trading fees are the top concerns. The exchanges are all fairly new and privately held. Several do not report basic information such as
686-681: A user's personal cryptocurrency wallet . Some can convert digital currency balances into anonymous prepaid cards which can be used to withdraw funds from ATMs worldwide while other digital currencies are backed by real-world commodities such as gold. The creators of digital currencies are typically independent of the digital currency exchange that facilitate trading in the currency. In one type of system, digital currency providers (DCP) are businesses that keep and administer accounts for their customers, but generally do not issue digital currency to those customers directly. Customers buy or sell digital currency from digital currency exchanges, who transfer
735-560: A well-defined purpose. (See Figure: Multi-layered Architecture of the DeFi Stack ). While they share common components of the first four layers, such as the Settlement layer , Asset layer , Protocol layer and Application layer , DEX aggregators have an additional component or Aggregator layer , which allows them to connect and interact with other DEXs via smart contracts. The Ethereum blockchain popularized smart contracts , which are
784-429: Is Uniswap , which is a decentralized exchange (DEX) set up to trade tokens issued on Ethereum. Rather than using a centralized exchange to fill orders, Uniswap pays users to form liquidity pools in exchange for a percentage of the fees collected from traders swapping tokens in and out of the liquidity pools. Because no centralized party runs Uniswap (the platform is governed by its users), and any development team can use
833-453: Is mostly significant for relatively large deals versus the liquidity pool size. Front running is a special type of attack in public blockchains when some participant (usually a miner) seeing an upcoming trading transaction puts his own transaction ahead (playing with a transaction fee for example), making the initial transaction less profitable or even reverted. To provide some protection against front running attacks, many DeFi exchanges offer
882-612: Is the founder of EtherDelta, who in November 2018 settled charges with the U.S. Securities and Exchange Commission over operating an unregistered securities exchange. Coding errors and hacks are common in DeFi. Blockchain transactions are irreversible, which means that an incorrect or fraudulent DeFi transaction cannot be corrected easily. The person or entity behind a DeFi protocol may be unknown and may disappear with investors' money. Investor Michael Novogratz has described some DeFi protocols as " Ponzi -like". DeFi has been compared to
931-899: The Australian Securities and Investments Commission (ASIC). The ASIC viewed the services offered as legally requiring an Australian Financial Services License , which the companies lacked. In 2006, U.S.-based digital currency exchange business Gold Age Inc., a New York state business, was shut down by the U.S. Secret Service after operating since 2002. Business operators Arthur Budovsky and Vladimir Kats were indicted "on charges of operating an illegal digital currency exchange and money transmittal business" from their apartments, transmitting more than $ 30 million to digital currency accounts. Customers provided limited identity documentation, and could transfer funds to anyone worldwide, with fees sometimes exceeding $ 100,000. Budovsky and Kats were sentenced in 2007 to five years in prison "for engaging in
980-520: The Bahamas , was charged by the US attorney’s office for the southern district of New York with fraud , conspiracy to commit money laundering , and conspiracy to defraud the US and violate campaign finance laws. In early 2018, Bloomberg News reported the largest cryptocurrency exchanges based on the volume and estimated revenues data collected by CoinMarketCap. Similar statistics was reported on Statista in
1029-478: The U.S. Securities and Exchange Commission maintained that "if a platform offers trading of digital assets that are securities and operates as an "exchange," as defined by the federal securities laws, then the platform must register with the SEC as a national securities exchange or be exempt from registration". The Commodity Futures Trading Commission now permits the trading of cryptocurrency derivatives publicly. Among
SECTION 20
#17328943662771078-523: The initial coin offering craze of 2017, part of a cryptocurrency bubble . Inexperienced investors are at particular risk of losing money because of the sophistication required to interact with DeFi platforms and the lack of any intermediary with customer support. On the other hand, as the code for DeFi smart contracts is generally open-source software that can be copied to set up competing platforms, experienced users and user-created bots might create instabilities as funds shift between platforms which share
1127-482: The AMM (Automated Market Makers) nature itself — the larger the deal, the stronger impact it has on the price. For example, if the constant product AMM is in use, every deal must keep the product xy = k constant, where x and y are quantities of two cryptocurrencies (or tokens) in the pool. Price impact is non-linear, so the larger is the input amount Δx, the lower is the final ratio y / x that gives an exchange price. The problem
1176-728: The Asian countries, Japan is more forthcoming and regulations mandate the need for a special license from the Financial Services Authority to operate a cryptocurrency exchange. China and Korea remain hostile, with China banning bitcoin miners and freezing bank accounts. While Australia is yet to announce its conclusive regulations on cryptocurrency, it does require its citizens to disclose their digital assets for capital gains tax . Decentralized exchange Decentralized finance (often stylized as DeFi ) provides financial instruments and services through smart contracts on
1225-592: The Bank Secrecy Act and agreed to pay a $ 10 million criminal fine. Reed was sentenced by U.S. District Court Judge John George Koeltl in New York to probation along with the other co-founders. Gregory Dwyer’s trial was initially scheduled for October 2022, and subsequently pled guilty and received a 12 month probation and $ 150,000 fine as punishment. On May 20, 2022, Hayes was sentenced to two years' probation, with home confinement for six months. On June 15, 2022, Delo
1274-460: The Bank Secrecy Act. He was released on $ 10 million bond pending future court proceedings in New York. On February 24, 2022, Delo and Hayes pled guilty to violating the Bank Secrecy Act by willfully failing to establish, implement, and maintain an anti-money laundering program at BitMEX. The pair agreed to separately pay a $ 10 million criminal fine representing pecuniary gain derived from the offense. On March 9, 2022, Reed pleaded guilty to violating
1323-623: The Mt. Gox hot wallet over time, beginning in late 2011. In December 2021 the MyCryptoWallet exchange called in liquidators . In June 2022, the US Securities and Exchange Commission launched an enquiry into Binance as an entity and not into the crypto products it was dealing in. On 11 November 2022, FTX , which was at that time the third largest cryptocurrency exchange by volume and valued at $ 18 billion, entered bankruptcy proceedings in
1372-604: The US court system, following what the exchange termed as "a liquidity crisis ". The financial impact of the collapse extended beyond the immediate FTX customer base, as reported, while, at a Reuters conference, financial industry executives said that "regulators must step in to protect crypto investors." Technology analyst Avivah Litan commented on the cryptocurrency ecosystem that "everything...needs to improve dramatically in terms of user experience, controls, safety, [and] customer service." On 13 December 2022, FTX founder and CEO Sam Bankman-Fried , after being extradited from
1421-623: The United Kingdom's first billionaire from bitcoin , and its youngest self-made billionaire. In July 2019, Nouriel Roubini , a critic of cryptocurrencies, suggested that the exchange is involved in illegal activities, allowing traders to take on too much risk and by trading against clients. Two days later, it was reported by Bloomberg that the Commodity Futures Trading Commission (CFTC) was investigating BitMEX as to whether they broke rules by allowing Americans to trade on
1470-585: The alleged founder, Arthur Budovsky Belanchuk, and four others were arrested in Costa Rica, Spain, and New York "under charges for conspiracy to commit money laundering and conspiracy and operation of an unlicensed money transmitting business." Budovsky, a former U.S. citizen and naturalized Costa Rican, was convicted in connection with the 2006 Gold Age raid. More than $ 40 million in assets were placed under restraint pending forfeiture , and more than 30 Liberty Reserve exchanger domain names were seized. The company
1519-563: The asset. Some DApps source external (off-chain) data, such as the price of an asset, through blockchain oracles . Additionally, Aave Protocol popularized "flash loans", which are uncollateralized loans of an arbitrary amount that are taken out and paid back within a single blockchain transaction. Max Wolff is credited with the original invention of flash loans with the original implementation released in 2018 by Marble Protocol. Many exploits of DeFi platforms have used flash loans to manipulate cryptocurrency spot prices. Another DeFi protocol

1568-447: The basis of DeFi, in 2017. Other blockchains have since implemented smart contracts. MakerDAO is a prominent lending DeFi platform based on a stablecoin that was established in 2017. It allows users to borrow DAI , a token pegged to the US dollar . Through a set of smart contracts that govern the loan, repayment, and liquidation processes, MakerDAO aims to maintain the stable value of DAI in
1617-503: The business of transmitting money without a license , a felony violation of state banking law", ultimately receiving sentences of five years' probation. In April 2007, the U.S. government ordered E-Gold administration to lock/block approximately 58 E-Gold accounts owned and used by The Bullion Exchange, AnyGoldNow, IceGold , GitGold, The Denver Gold Exchange, GoldPouch Express, 1MDC (a Digital Gold Currency , based on e-gold ) and others, forcing G&SR (owner of OmniPay) to liquidate
1666-416: The decentralized exchange. Decentralized exchanges are also more anonymous than exchanges that implement know your customer (KYC) requirements. There are some signs that decentralized exchanges have been suffering from low trading volumes and reduced market liquidity . The 0x project , a protocol for building decentralized exchanges with interchangeable liquidity, attempts to solve this issue. Due to
1715-449: The developers and influencers promote a project and then take the money, as a form of pump-and-dump . In October 2021, the FATF included DeFi in the guidance for crypto service providers, making the authority's aim to regulate this type of asset.They are expecting each individual country to determine if individuals involved in DeFi can be considered a virtual asset provider and be subjected to
1764-748: The digital currency exchanges operate outside the Western countries to avoid regulation and prosecution. However, they do handle Western fiat currencies and maintain bank accounts in several countries to facilitate deposits in various national currencies. Decentralized exchanges such as Etherdelta, IDEX and HADAX do not store users' funds on the exchange, but instead facilitate peer-to-peer cryptocurrency trading. Decentralized exchanges are resistant to security problems that affect other exchanges, but as of mid 2018 suffer from low trading volumes. In 2004 three Australian -based digital currency exchange businesses voluntarily shut down following an investigation by
1813-581: The digital currency into or out of the customer's DCP account. Some exchanges are subsidiaries of DCP, but many are legally independent businesses. The denomination of funds kept in DCP accounts may be of a real or fictitious currency. A digital currency exchange can be a brick-and-mortar business or a strictly online business. As a brick-and-mortar business, it exchanges traditional payment methods and digital currencies. As an online business, it exchanges electronically transferred money and digital currencies. Often,
1862-539: The most popular e-currencies like E-gold, Liberty Reserve and others. Also in July 2008 E-gold's three directors accepted a bargain with the prosecutors and pleaded guilty to one count of "conspiracy to engage in money laundering" and one count of the "operation of an unlicensed money transmitting business". E-gold ceased operations in 2009. In 2013, Jean-Loup Richet, a research fellow at ESSEC ISIS, surveyed new money laundering techniques that cybercriminals were using in
1911-789: The names of the owners, financial data, or even the location of the business. By 2016, several cryptocurrency exchanges operating in the European Union obtained licenses under the EU Payment Services Directive and the EU Electronic Money Directive . The adequacy of such licenses for the operation of a cryptocurrency exchange has not been judicially tested. The European Council and the European Parliament announced that they will issue regulations to impose stricter rules targeting exchange platforms. In 2018,
1960-459: The need for an intermediary. The lack of an intermediary differentiates them from centralized exchanges (CEX). In transactions made through decentralized exchanges, the typical third party entities which would normally oversee the security and transfer of assets (e.g. banks , stockbrokers , online payment gateways , government institutions , etc.) are substituted by a blockchain or distributed ledger . Some common methods of operation include
2009-448: The open-source software, there is no entity to check the identities of the people using the platform and meet KYC/AML regulations. As of 2020, it is not clear what position regulators will take on the legality of such platforms. Decentralized exchanges (DEX) are a type of cryptocurrency exchange , which allow for either direct peer-to-peer , or Automated Market Maker (AMM) liquidity pool cryptocurrency transactions to take place without

2058-565: The platform. On October 1, 2020, Hayes, Reed, Delo, and Gregory Dwyer were indicted on charges of violating the U.S. Bank Secrecy Act and conspiracy to violate that law, arising from allegations that the four failed to implement anti-money laundering measures. The case name is "U.S. v. Hayes et al ", case number of 20-cr-00500, in the U.S. District Court for the Southern District of New York. On April 6, 2021, former BitMEX CEO Arthur Hayes turned himself in to face U.S. charges for violating
2107-403: The risks presented by crypto-assets already valued at $ 2.5 trillion was a particular challenge for US regulators. DeFi revolves around decentralized applications , also known as DApps, that perform financial functions on distributed ledgers called blockchains, a technology that was made popular by Bitcoin and has since been adapted more broadly. Rather than transactions being made through
2156-434: The same code. In addition, DeFi platforms might inadvertently provide incentives for cryptocurrency miners to destabilize the system. In 2021, half of cryptocurrency crime was related to DeFi. This rise has been attributed to a combination of developer incompetence and non-existent or poorly enforced regulations. Theft from DeFi can come from either external hackers stealing from vulnerable projects, or "rug pulls", where
2205-493: The seized assets. A few weeks later, E-Gold faced four indictments. Following the launch of a decentralized cryptocurrency bitcoin in 2008 and the subsequent introduction of other cryptocurrencies, many virtual platforms were created specifically for the exchange of decentralized cryptocurrencies. Their regulation differs from country to country. In July 2008, WebMoney changed its rules, affecting many exchanges. Since that time it became prohibited to exchange WebMoney to
2254-460: The underlying assets. BitMEX was founded in 2014 by Arthur Hayes , Ben Delo , and Samuel Reed, with financing from family and friends. Bitmex completed a SAFE round of investment in July 2015 then shortly after was inducted into SOSV batch 8 china accelerator program where it sold equity in exchange for labour and financing. In 2016, the exchange introduced perpetual futures , which became its most popular derivative product. In 2018, Delo became
2303-412: The use of smart contracts or order book relaying – although many other variations are possible, with differing degrees of decentralization . Because traders on a decentralized exchange often do not need to transfer their assets to the exchange before executing a trade, decentralized exchanges reduce the risk of theft from hacking of exchanges , but liquidity providers do need to transfer tokens to
2352-461: Was estimated to have laundered $ 6 billion in criminal proceeds. In February 2014, Mt. Gox , the largest cryptocurrency exchange at the time, suspended trading, closed its website and exchange service, and filed for bankruptcy protection in Japan from creditors. In April 2014, the company began liquidation proceedings. This was the result of a large theft of bitcoins that were stolen straight out of
2401-652: Was sentenced to 30 months' probation and as a UK citizen returned to Hong Kong subsequently to serve his probation. In July 2024, BitMex pleaded guilty to violating the Bank Secrecy Act due to failing to maintain an adequate anti- money laundering program. Cryptocurrency exchange Some brokerages which also focus on other assets such as stocks, like Robinhood and eToro , let users purchase but not withdraw cryptocurrencies to cryptocurrency wallets . Dedicated cryptocurrency exchanges such as Binance and Coinbase do allow cryptocurrency withdrawals, however. A cryptocurrency exchange can typically send cryptocurrency to
