In a statement on its website Thursday, Mt. Gox has said it found 200,000 of the bitcoins it claimed may have disappeared as a result of a software flaw. That find reduces the number of bitcoins missing to 650,000. The bitcoins were found in an old-format digital wallet.



The 200,000 bitcoins were worth about $116 million at market price Friday.

Mark Karpelès, Mt. Gox’s CEO, wrote that the wallet in which the bitcoins were found was used in the past and the exchange thought it no longer held any bitcoins.

Karpelès has said that he thought the loss was due to a defect or ‘bug’ in the bitcoin software algorithm. That “bug” supposedly allowed someone to hack the system.

The loss is still under investigation.
