Early Bitcoin ($BTC) entrepreneur Charlie Shrem is pushing back against an accusation that he stole 5,000 bitcoin from Tyler and Cameron Winklevoss, according to recently-published court filings. The Winklevoss brothers sued Shrem in September, claiming that while they paid him $1 million to purchase bitcoin on their behalf in September 2012, he failed to deliver 5,000 coins, instead keeping them for himself. At press time, they would be worth approximately $32 million.
