United Kingdom vs United States

The UK has an evolving and increasingly comprehensive crypto regulatory framework. The FCA registers crypto firms for AML/CFT compliance and has imposed strict financial promotion rules requiring risk warnings and banning incentives. HMRC treats crypto as property subject to Capital Gains Tax (10% basic rate, 20% higher rate, with £3,000 annual exemption from 2024/25). The Financial Services and Markets Act 2023 brought crypto assets into the UK regulatory perimeter, and HM Treasury is developing rules for a full crypto regime including exchange licensing, stablecoin regulation, and a potential UK CBDC ('Britcoin').

The United States has the world's most complex crypto regulatory landscape, with overlapping federal and state jurisdictions. The SEC regulates crypto securities and has pursued enforcement actions against exchanges and token issuers. The CFTC oversees crypto derivatives and considers Bitcoin a commodity. FinCEN applies BSA requirements to crypto exchanges as money service businesses. The IRS taxes crypto as property: short-term gains at income tax rates (10-37%), long-term gains at 0-20%. New 1099-DA broker reporting rules take effect from 2025. Multiple states have their own requirements, with New York's BitLicense being the most stringent.
