Cryptocurrency exchange

• 1. Introduction

  ›

  Cryptocurrency exchanges sit at the crossroads of a financial revolution and a long trail of scandal. On the 11th of November 2022, FTX, the third largest cryptocurrency exchange by volume and valued at $18 billion, filed for bankruptcy in the US court system. What the exchange itself called a "liquidity crisis" turned out to be something far darker. The collapse sent tremors through the entire cryptocurrency ecosystem, prompting financial industry executives at a Reuters conference to say that regulators must step in to protect crypto investors.

  But FTX was not an isolated case. Long before that collapse, the history of cryptocurrency exchanges was already dotted with shutdowns, indictments, money laundering schemes, and stolen billions. How did these trading platforms come to occupy such a central and contested role in global finance? And what makes them so structurally vulnerable to the crises that have defined them?

• 2. How Exchanges Work

  ›

  At its core, a cryptocurrency exchange is a business that lets customers swap digital currencies for other assets, including conventional fiat money. Some act as market makers, earning revenue through the spread between buying and selling prices. Others operate as matching platforms that simply charge a flat fee per transaction.

  Decentralized exchanges such as Etherdelta, IDEX, and HADAX take a different approach altogether. Rather than holding users' funds, they facilitate peer-to-peer trading directly. That structure makes them resistant to the security failures that have plagued centralized platforms, but it also tends to produce lower trading volumes.

  Some exchanges convert digital currency balances into anonymous prepaid cards, allowing users to withdraw funds from ATMs worldwide. Others hold currencies backed by real-world commodities such as gold. The range of models reflects just how varied the exchange landscape has become since the earliest digital currency businesses first appeared.

• 3. Early Crackdowns

  ›

  In 2004, three Australian-based digital currency exchange businesses voluntarily shut down after an investigation by the Australian Securities and Investments Commission. The ASIC had determined that what these companies offered legally required an Australian Financial Services License, which none of them held.

  Two years later, a New York state business called Gold Age Inc. was shut down by the US Secret Service after operating since 2002. Its operators, Arthur Budovsky and Vladimir Kats, were indicted on charges of running an illegal digital currency exchange and money transmittal business. They had been operating out of their apartments, transmitting more than $30 million to digital currency accounts. Customers were allowed to transfer funds to anyone worldwide, with fees sometimes exceeding $100,000.

  Budovsky and Kats were sentenced in 2007 to five years' probation for engaging in the business of transmitting money without a license, a felony under state banking law. Their case set an early precedent: regulators in Western countries were watching, and they were willing to act.

• 4. The E-Gold Collapse

  ›

  In April 2007, the US government ordered the administrators of E-Gold to lock approximately 58 accounts connected to a network of exchange services with names like AnyGoldNow, IceGold, GitGold, and the Denver Gold Exchange. The action forced G&SR, the owner of OmniPay, to liquidate the seized assets.

  A few weeks later, E-Gold itself faced four separate indictments. By July 2008, the exchange's three directors had struck a bargain with prosecutors, each pleading guilty to conspiracy to engage in money laundering and the operation of an unlicensed money transmitting business. E-Gold ceased operations entirely in 2009.

  In July 2008, WebMoney also revised its rules, cutting off exchanges from the ability to trade with popular e-currencies like E-gold and Liberty Reserve. The tightening of financial networks around these platforms signaled that the era of informal, lightly regulated digital currency businesses was drawing to a close, even as a new chapter was about to begin.

• 5. Bitcoin and the Laundering Era

  ›

  Bitcoin launched in 2008 as a decentralized cryptocurrency, and in its wake came a proliferation of virtual trading platforms built specifically for decentralized currencies. Their legal status varied dramatically from country to country.

  In 2013, a research fellow named Jean-Loup Richet at ESSEC ISIS documented new money laundering methods for a report commissioned by the United Nations Office on Drugs and Crime. A common approach he identified involved using digital currency exchangers to convert US dollars into Liberty Reserve, a service that allowed funds to be sent and received anonymously. The receiver could then convert the Liberty Reserve currency back into cash for a small fee.

  In May 2013, Liberty Reserve itself was shut down. Its alleged founder, Arthur Budovsky Belanchuk, was arrested along with four others in Costa Rica, Spain, and New York, charged with conspiracy to commit money laundering and operating an unlicensed money transmitting business. More than $40 million in assets were frozen pending forfeiture, and more than 30 Liberty Reserve exchanger domain names were seized. Investigators estimated that the company had laundered $6 billion in criminal proceeds. Budovsky had previously been convicted in connection with the 2006 Gold Age raid.

• 6. The Mt. Gox Disaster

  ›

  In February 2014, Mt. Gox, then the largest cryptocurrency exchange in the world, suspended all trading and shuttered its website. The exchange filed for bankruptcy protection in Japan, and by April 2014 had begun formal liquidation proceedings.

  The cause was a theft that had been unfolding quietly since late 2011. Bitcoins had been stolen directly from the Mt. Gox hot wallet over an extended period, in a breach that went undetected until the damage was irreversible. The collapse was a watershed moment for the industry, demonstrating that even the most prominent exchange in the world was not immune to catastrophic failure.

  The Mt. Gox case prompted regulators around the world to consider whether existing financial laws were adequate to govern cryptocurrency platforms. Japan moved to mandate a special license from its Financial Services Authority for any exchange operating there. Other countries were slower to act, but the direction of travel had shifted.

• 7. Regulation Takes Shape

  ›

  By 2016, several cryptocurrency exchanges operating in the European Union had obtained licenses under the EU Payment Services Directive and the EU Electronic Money Directive, though whether those licenses were legally sufficient for cryptocurrency trading had never been tested in court.

  In 2018, the US Securities and Exchange Commission clarified its position: any platform trading digital assets that qualify as securities and operating as an exchange under federal law must register with the SEC as a national securities exchange or claim a valid exemption. That same year, the SEC launched an inquiry into Binance as an entity, a move that focused on the company itself rather than on the specific products it traded.

  In 2023, the European Union introduced the MiCA regulation, which required all cryptocurrency exchanges operating in the EU to obtain a license under the new framework by the 1st of July 2026. The regulation represented the most comprehensive attempt yet by a major jurisdiction to bring digital currency trading under a consistent legal standard.

  The collapse of FTX on the 11th of November 2022 added new urgency to these efforts. Sam Bankman-Fried, FTX's founder and CEO, was extradited from the Bahamas and charged on the 13th of December 2022 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. Technology analyst Avivah Litan captured the mood when she observed that everything in the cryptocurrency ecosystem needed to improve dramatically in terms of user experience, controls, safety, and customer service.
