Overview

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, let users purchase but not withdraw cryptocurrencies to cryptocurrency wallets while dedicated cryptocurrency exchanges do allow cryptocurrency withdrawals.

Operation

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 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 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.

2004–2008 Pre crypto regulatory issues

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.

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 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 the seized assets.

2008–2014 advent of crypto currency

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". E-gold ceased operations in 2009.

2014 to present

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 the Mt. Gox hot wallet over time, beginning in late 2011.

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 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 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.
