Odaily Planet Daily News The lawyer for Alexander Vinnik, operator of the crypto exchange BTC-e, believes that Vinnik may be considered for a prisoner exchange between the United States and the Russian Federation. Vinnik's representative in the United States, David Rizk, commented on Vinnik's possible return to the country in an interview with RIA Novosti. "I wouldn't rule it out," he said. Vinnik has been in U.S. custody since his extradition from Greece last August. U.S. authorities accused him of laundering at least $4 billion through the now-shuttered BTC-e. If convicted, the 43-year-old Russian faces up to 55 years in prison. (Bitcoin.com)
