By Nate Raymond and Gertrude Chavez-Dreyfuss (Reuters) – The U.S. Marshals Service had one winner in its auction of nearly 30,000 bitcoin, a spokeswoman said on Tuesday, without revealing the name of the successful bidder. The U.S. Marshals Service held an auction on Friday for 29,655 bitcoin seized during a raid on Silk Road, an Internet black-market bazaar where authorities say illegal drugs and other goods could be obtained. The winner was notified on Monday evening and the transfer of bitcoin took place Tuesday, according to Lynzey Donahue, spokeswoman for the USMS. Barry Silbert of SecondMarket Holdings, which runs a bitcoin investment platform, said on Monday his firm was outbid, as did hedge fund Pantera Capital, which bid below the market price, according to Pantera chief executive Dan Morehead.
