In October 2022, Bittrex was fined a combined $29 million by the US Office of Foreign Assets Control (OFAC) and the Financial Crimes Enforcement Network (FinCEN). The OFAC fine pertained to Bittrex's service of users based in Crimea, Cuba, Iran, Sudan, and Syria, who altogether performed $263 million in transactions using the platform. FinCEN's fine was imposed as a result of alleged "willful violations" of requirements around anti-money laundering and suspicious activity reports.
Bittrex will continue operations outside of the US, and currently operate in Europe, South America, and elsewhere.
