On Wednesday, the U.S. Treasury's Financial Crimes Enforcement Network (FinCEN) announced a $110 million fine against BTC-e for facilitating crimes like drug sales and ransomware attacks along with a separate $12 million fine against its owner, Alexander Vinnik.

BTC-e is headquartered in Russia and has long served as a forum where users can exchange traditional currencies for bitcoin or other digital monies like Ethereum or Dash.

Meanwhile on Wednesday, the U.S. Justice Department also filed a series of criminal charges, including conspiracy and money laundering, against Vinnik after snatching him up in Greece.
