Alexander Vinnik, 38, is accused of laundering more than $4 billion in bitcoin for culprits involved in hacking attacks, tax fraud and drug trafficking. U.S. authorities say he was responsible for facilitating crimes ranging from computer hacking to drug trafficking since at least 2011 through his digital Bitcoin exchange BTC-e. He has denied all charges against him, saying he was just a technical consultant to the exchange and not its operator. Vinnick is trying to return to his home in Russia, where he is facing lesser fraud charges, although a hearing date for Russian extradition request has not yet been set.
