It seems that Mt. Gox, the bitcoin exchange site that recently declared bankruptcy, might be able to recoup some of those costs. After research its bitcoin wallet from 2011 and more recent, Mt. Gox has found 200,000 bitcoins in an old-format wallet. Worth about $114 million, this is only about 24% of the bitcoins that were stolen from Mt. Gox last month, according to the New York Times.
