LOS ANGELES (MarketWatch) — Shuttered bitcoin exchange Mt. Gox said it has found 200,000 of its missing 850,000 bitcoins, The Wall Street Journal reported, citing a document from the Tokyo-based company. The funds were discovered March 7 in a virtual “wallet” that Mt. Gox had stopped using, the report quoted Mt. Gox Chief Executive Mark Karpelès as saying. Mt. Gox filed for bankruptcy protection at the end of last month, with reports saying the exchange may have fallen victim to hacking in its loss of the bitcoins.
