This article systematically reviews the compliance evolution of the crypto industry from 2016 to 2021, focusing on two major phases: the era of industry self-regulation (2016–2018) and the licensing era (2019–2021). During the first phase, the ICO craze gave rise to the SAFT framework, but the DAO Report established for the first time that certain tokens constitute securities under U.S. law, triggering a regulatory crackdown. In the second phase, the FATF Travel Rule was implemented, multiple jurisdictions established exchange licensing regimes, BitMEX faced criminal prosecution signaling the end of offshore immunity, and China's '924 Notice' completely banned virtual currency trading.
Industry Self-Regulation Era (2016–2018): ICO Mania and Awakening Regulators
From 2016 to 2018, the crypto industry experienced unprecedented growth, with ICOs raising over $6 billion globally in 2017 alone. The SAFT (Simple Agreement for Future Tokens) framework emerged as an attempt to offer tokens in compliance with securities laws by selling rights to accredited investors first. However, the SEC's DAO Report in July 2017 determined that tokens issued by The DAO were securities, undermining the SAFT model. In September 2017, China banned all ICO fundraising and shut down domestic exchanges, signaling the end of the 'wild west' era.
Licensing Era (2019–2021): Global Regulatory Framework Takes Shape
By 2019, the focus shifted from defining token classification to constructing exchange licensing regimes. The FATF's Travel Rule, issued in June 2019, required VASPs to collect and share transaction details, extending AML obligations to crypto. Jurisdictions like New York (BitLicense), Singapore (MAS), Hong Kong (SFC), and Japan (FSA) introduced or updated licensing regimes. By 2021, over 50 major exchanges held recognized licenses, and compliant exchanges accounted for roughly 35% of global trading volume, up from under 10% in 2019.
The case against BitMEX in October 2020 was a watershed moment: U.S. prosecutors charged the exchange's founders with violating the Bank Secrecy Act, demonstrating that offshore registration does not shield platforms from U.S. jurisdiction. This forced many offshore exchanges to adopt KYC/AML procedures and restrict U.S. users. China's '924 Notice' in September 2021 declared all overseas exchanges serving mainland Chinese residents illegal, leading to a massive exodus of miners and traders. The cumulative effect of these events marked the end of the unregulated offshore model and accelerated the industry's shift toward institutional-grade compliance.
