A grand jury in the Northern District of California indicted a Russian man for running a massive money laundering operation through the BTC-e bitcoin exchange, a group of federal officials announced Wednesday. The exchange allegedly received up to $4 billion in proceeds from various criminal activities, including the 2014 hack of the Mt. Gox bitcoin exchange. The suspect, 37-year-old Alexander Vinnik, was arrested Tuesday by Greek authorities, and charges in an unsealed indictment were released the following day.
