The US government fined digital asset exchange Bittrex $53 million, the largest fine imposed by the Treasury Department on a crypto business to date. The Treasury’s Office of Foreign Assets Control (OFAC) and Financial Crimes Enforcement Network (FinCEN) announced on Tuesday that the US exchange would be fined $24 million and $29 million, respectively, for “apparent violations” of multiple US sanctions programmes. According to the authorities, Bittrex, based in Bellevue, Washington, “unnecessarily exposed the US financial system to threat actors.”
