Regulatory first salvos

Guidance lands

FinCEN’s 2013 memo

In March 2013, U.S. FinCEN issued guidance labeling “administrators” and “exchangers” of convertible virtual currency as money services businesses (MSBs). Translation: if you run an exchange, register, implement AML, file SARs. It was the first major signal that crypto would be folded into existing rules, not given a free pass (the original PDF ↗ is still on FinCEN’s site).

Some exchanges registered; others ignored or geofenced the U.S. The memo anchored later enforcement, including seizures tied to unlicensed money transmission.

Banking headaches

Banks began dropping crypto clients to avoid perceived risk. Exchanges scrambled for new banking partners, pushed users to wire through intermediaries, or leaned on payment processors. Losing fiat rails became an existential threat, showing how traditional finance could throttle crypto without touching the protocol.

Licenses, clampdowns, and bank exits

China’s 2013 circulars

In December 2013, China barred banks from handling Bitcoin transactions, citing risk to financial stability. Exchanges pivoted to vouchers and OTC desks. The move foreshadowed China’s later mining crackdowns and set a template: banks are chokepoints even if the chain keeps running. A translation of the circular lives on the CoinDesk archive ↗.

NYDFS BitLicense draft

Ben Lawsky’s New York Department of Financial Services proposed the BitLicense in 2014. It demanded capital requirements, compliance officers, and reporting. Critics saw it as too heavy; some companies exited New York (“BitExodus”). Others complied to access U.S. markets. The draft debate defined the gap between crypto’s permissionless ethos and state-level licensure (the NYDFS history page ↗ tracks its versions).

Early subpoenas and enforcements

Regulators and law enforcement issued subpoenas to exchanges and mixers. Cases against Liberty Reserve and later crypto exchangers reinforced that “we’re just software” wouldn’t fly when custody and fiat touchpoints were involved.

Why it set the tone

Crypto as money transmission

These early moves framed crypto businesses as financial institutions subject to KYC/AML. That framing persists globally. Even jurisdictions with lighter touch still expect some identity checks for fiat bridges.

Compliance becomes a moat

Exchanges that invested in compliance survived bank de-risking and could scale. Others stayed gray or off-shore, trading higher risk for speed. This split shaped which firms became household names versus cautionary tales.

Catalyst for stable workarounds

Bank clampdowns pushed users toward OTC trades, peer-to-peer deals, and later stablecoins as settlement tools. The regulatory squeeze indirectly spurred innovation in alternative rails.

Enduring narrative

Media and policymakers began viewing crypto through the lens of AML, consumer protection, and systemic risk. Each subsequent boom revisits these themes. The first salvos set expectations: if you touch fiat or custody, expect licenses and audits.
