The U.S. Department of Justice indicted two Russian citizens for hacking the Mt.Gox cryptocurrency exchange and laundering 647,000 bitcoins.
The agency said in a statement that Alexei Biliuchenko, 43, and Alexander Werner, 29, were charged with conspiracy to launder bitcoins in the hacking of Mt.Gox, which collapsed in 2014 after losing half a billion dollars worth of crypto assets.
“For years, Biliuchenko and his associates allegedly operated a digital currency exchange that allowed billions of dollars to be laundered by criminals around the world, including computer hackers, ransomware creators, drug gangs and corrupt government officials,” said prosecutor Ismail Ramsey.
Biliuchenko is also accused of conspiring with Alexander Vinnik to run the BTC-e crypto exchange from 2011 to 2017. 
Vinnik is now in U.S. custody on charges of laundering up to $9 billion through BTC-e. It was recently reported that Vinnik is trying to get him included in any prisoner exchange between Moscow and Washington;
Mt.Gox was once the world’s largest bitcoin trading venue, accounting for about 90 percent of the first cryptocurrency’s total trading volume. In April 2014, the exchange filed for liquidation due to the loss of 850,000 BTC due to a hacker attack. The bankruptcy procedure of the stock exchange is still underway. Only recently, the crypto-exchange started paying its customers.
