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.
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 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 [1] [2] while other digital currencies are backed by real-world commodities such as gold. [3]
The creators of digital currencies are typically independent of the digital currency exchange that facilitate trading in the currency. [2] 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. [4] [5] Customers buy or sell digital currency from digital currency exchanges, who transfer the digital currency into or out of the customer's DCP account. [5] Some exchanges are subsidiaries of DCP, but many are legally independent businesses. [4] The denomination of funds kept in DCP accounts may be of a real or fictitious currency. [5]
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. [4]
Often, 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. [1] [2]
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 mid2018 [update] suffer from low trading volumes. [6]
In 2004 three Australian-based digital currency exchange businesses voluntarily shut down following an investigation by 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. [7]
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. [8] 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. [5] Customers provided limited identity documentation, and could transfer funds to anyone worldwide, with fees sometimes exceeding $100,000. [5] Budovsky and Kats were sentenced in 2007 to five years in prison "for engaging in the business of transmitting money without a license, a felony violation of state banking law", ultimately receiving sentences of five years' probation. [9]
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 the seized assets.[ citation needed ]
A few weeks later, E-Gold faced four indictments. [10]
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[ by whom? ] to exchange WebMoney to 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". [11] 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 a report written for the United Nations Office on Drugs and Crime. [12] 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 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." [13] Budovsky, a former U.S. citizen and naturalized Costa Rican, was convicted in connection with the 2006 Gold Age raid. [9] More than $40 million in assets were placed under restraint pending forfeiture, and more than 30 Liberty Reserve exchanger domain names were seized. [13] [14] The company was estimated to have laundered $6 billion in criminal proceeds. [13]
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. [15] [16] In April 2014, the company began liquidation proceedings. [17] This was the result of a large theft of bitcoins that were stolen straight out of the Mt. Gox hot wallet over time, beginning in late 2011. [18] [19]
In December 2021 the MyCryptoWallet exchange called in liquidators. [20]
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. [21]
On 11 November 2022, FTX, which was at that time the third largest cryptocurrency exchange by volume and valued at $18 billion, [22] entered bankruptcy proceedings in the US court system, following what the exchange termed as "a liquidity crisis". [23] [24] [25] [26] The financial impact of the collapse extended beyond the immediate FTX customer base, as reported, [27] while, at a Reuters conference, financial industry executives said that "regulators must step in to protect crypto investors." [28] 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." [29] On 13 December 2022, FTX founder and CEO Sam Bankman-Fried, after being extradited from 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. [30]
In early 2018, Bloomberg News reported the largest cryptocurrency exchanges based on the volume and estimated revenues data collected by CoinMarketCap. [31] Similar statistics was reported on Statista in 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. [32] [33] The exchanges are all fairly new and privately held. Several do not report basic information such as the names of the owners, financial data, or even the location of the business. [34]
By 2016, several cryptocurrency exchanges operating in the European Union obtained licenses under the EU Payment Services Directive and the EU Electronic Money Directive. [35] 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, 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". [36] The Commodity Futures Trading Commission now permits the trading of cryptocurrency derivatives publicly. [37]
Among 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. [38] China and Korea remain hostile, with China banning bitcoin miners and freezing bank accounts. [39] [40] 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. [41]
Digital currency is any currency, money, or money-like asset that is primarily managed, stored or exchanged on digital computer systems, especially over the internet. Types of digital currencies include cryptocurrency, virtual currency and central bank digital currency. Digital currency may be recorded on a distributed database on the internet, a centralized electronic computer database owned by a company or bank, within digital files or even on a stored-value card.
Virtual currency, or virtual money, is a digital currency that is largely unregulated, issued and usually controlled by its developers, and used and accepted electronically among the members of a specific virtual community. In 2014, the European Banking Authority defined virtual currency as "a digital representation of value that is neither issued by a central bank or a public authority, nor necessarily attached to a fiat currency but is accepted by natural or legal persons as a means of payment and can be transferred, stored or traded electronically." A digital currency issued by a central bank is referred to as a central bank digital currency.
Bitcoin is the first decentralized cryptocurrency. Nodes in the peer-to-peer bitcoin network verify transactions through cryptography and record them in a public distributed ledger, called a blockchain, without central oversight. Consensus between nodes is achieved using a computationally intensive process based on proof of work, called mining, that guarantees the security of the bitcoin blockchain. Mining consumes increasing quantities of electricity and has been criticized for its environmental effects.
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.
Mt. Gox was a bitcoin exchange based in Shibuya, Tokyo, Japan. Launched in 2010, it was handling over 70% of all bitcoin (BTC) buys/sells worldwide by early 2014, when it abruptly ceased operations amid revelations of its involvement in the loss/theft of hundreds of thousands of bitcoins, then worth hundreds of millions in US dollars.
Coinbase Global, Inc., branded Coinbase, is an American publicly traded company that operates a cryptocurrency exchange platform. Coinbase is a distributed company; all employees operate via remote work. It is the largest cryptocurrency exchange in the United States in terms of trading volume. The company was founded in 2012 by Brian Armstrong and Fred Ehrsam. In May 2020, Coinbase announced it would shut its San Francisco, California, headquarters and change operations to remote-first, part of a wave of several major tech companies closing headquarters in San Francisco in the wake of the COVID-19 pandemic.
Bitstamp is a European cryptocurrency exchange founded in 2011. It is the world’s longest-running cryptocurrency exchange. It allows trading between fiat currency, Bitcoin and other cryptocurrencies, such as USD, EUR, GBP, Ethereum, Litecoin, Ripple, Bitcoin Cash, Algorand, Stellar, and USD Coin. Business operations are conducted from its registered headquarters in Luxembourg City, with a satellite office in Ljubljana.
Bitcoin is a cryptocurrency, a digital asset that uses cryptography to control its creation and management rather than relying on central authorities. Originally designed as a medium of exchange, Bitcoin is now primarily regarded as a store of value. The history of bitcoin started with its invention and implementation by Satoshi Nakamoto, who integrated many existing ideas from the cryptography community. Over the course of bitcoin's history, it has undergone rapid growth to become a significant store of value both on- and offline. From the mid-2010s, some businesses began accepting bitcoin in addition to traditional currencies.
Blockchain.com is a cryptocurrency financial services company. The company began as the first Bitcoin blockchain explorer in 2011 and later created a cryptocurrency wallet that accounted for 28% of bitcoin transactions between 2012 and 2020. It also operates a cryptocurrency exchange and provides institutional markets lending business and data, charts, and analytics.
CoinDesk is a news site specializing in bitcoin and digital currencies. Founded by Shakil Khan, the firm also provides guides to bitcoin for those new to digital currencies.
Kraken is a United States–based cryptocurrency exchange, founded in 2011. It was one of the first bitcoin exchanges to be listed on Bloomberg Terminal and was valued at US$3 billion in January 2024. The company has been the subject of several regulatory investigations since 2018, and has agreed to cumulative fines of over $30 million.
Digital Currency Group (DCG) is a venture capital company focusing on the digital currency market. It is located in Stamford, Connecticut. The company has the subsidiaries Foundry, Genesis, Grayscale Investments, and Luno. It also formerly owned CoinDesk.
ShapeShift, founded in 2014 by Erik Voorhees was a cryptocurrency exchange headquartered in Switzerland that turned into a permissionless DAO operating on the blockchain. Its decentralized application empowers users to trade the Bitcoin, Ethereum, and 10,000+ crypto assets across 14 chains.
Bitfinex is a cryptocurrency exchange owned and operated by iFinex Inc, and is registered in the British Virgin Islands. Bitfinex was founded in 2012. It was originally a peer-to-peer Bitcoin exchange, and later added support for other cryptocurrencies.
A cryptocurrency wallet is a device, physical medium, program or an online service which stores the public and/or private keys for cryptocurrency transactions. In addition to this basic function of storing the keys, a cryptocurrency wallet more often offers the functionality of encrypting and/or signing information. Signing can for example result in executing a smart contract, a cryptocurrency transaction, identification, or legally signing a 'document'.
A cryptocurrency bubble is a phenomenon where the market increasingly considers the going price of cryptocurrency assets to be inflated against their hypothetical value. The history of cryptocurrency has been marked by several speculative bubbles.
Binance Holdings Ltd., branded Binance, is a global company that operates the largest cryptocurrency exchange in terms of daily trading volume of cryptocurrencies. Binance was founded in 2017 by Changpeng Zhao, a developer who had previously created high-frequency trading software. Binance was initially based in China, then moved to Japan shortly before the Chinese government restricted cryptocurrency companies. Binance subsequently left Japan for Malta and currently has no official company headquarters.
Cryptocurrency and crime describe notable examples of cybercrime related to theft of cryptocurrencies and some methods or security vulnerabilities commonly exploited. Cryptojacking is a form of cybercrime specific to cryptocurrencies that have been used on websites to hijack a victim's resources and use them for hashing and mining cryptocurrency.
The Bitfinex cryptocurrency exchange was hacked in August 2016. 119,756 bitcoin, worth about US$72 million at the time, was stolen.
Erik Tristan Voorhees is an American cryptocurrency entrepreneur and founder of the cryptocurrency exchange ShapeShift. He also co-founded Satoshi Dice and was the Director of Marketing at BitInstant. He has been referred to as a crypto-libertarian and has advocated for "the separation of money and state".
