FinCEN is like the vigilant lifeguard at a busy swimming pool, ensuring nobody sneaks in dirty towels—or in this case, illicit funds. Part of the U.S. Treasury, FinCEN enforces anti-money laundering (AML) and know-your-customer (KYC) guidelines. Crypto exchanges and custodial services must comply with its regulations, such as reporting suspicious activities or verifying customer identities. While some argue these measures protect consumers and prevent crime, others see heavy-handed oversight as a potential threat to financial privacy. Regardless, if you operate a Bitcoin-related business in the U.S., staying on FinCEN’s good side isn’t optional.
