Greece’s top administrative court has ruled in favor of extraditing to France a Russian man suspected of laundering billions of dollars in digital currency, a judicial official said on Thursday. The Greek justice minister had in December ordered the extradition of Alexander Vinnik, who is accused of masterminding a $4 billion bitcoin laundering ring and is wanted by both France and the United States. U.S. authorities accuse Vinnik of running BTC-e – a digital currency exchange used to trade bitcoin – to facilitate crimes ranging from computer hacking to drug trafficking since 2011.
