Bitcoin makes the BSA's structural problem impossible to ignore.
The BSA assumes financial surveillance works because money flows through intermediaries (banks). Those intermediaries become compliance agents by force. It's a brittle architecture — the moment money bypasses the intermediary, the whole system collapses.
Bitcoin self-custody is exactly that bypass. FinCEN acknowledged this in 2013 and again in 2019: holders of BTC "for their own account" are not money transmitters and don't trigger BSA requirements. The custodian is required to comply; the user is not.
The result: a two-tier world. Coinbase, Kraken, etc. run compliance teams bigger than their engineering teams — SARs, CTRs, KYC, OFAC screening. Meanwhile anyone holding their own keys has zero BSA obligation regardless of transaction size.
The FATF "Travel Rule" and the 2020 FinCEN proposed rule on unhosted wallets tried to close this gap, but both foundered on the technical impossibility of enforcing data collection at the point of self-custody.
The BSA is a 1970 solution to a 1970 problem. Self-sovereign money breaks the assumption the whole regime was built on.
