Mt. GOx opens old digital wallet from 2011.
The defunct bitcoin exchange Mt.Gox has reportedly found about a quarter of the Bitcoins that were previously considered to be lost or stolen, in an old digital wallet.
Once the world’s largest Bitcoin exchange uncovered nearly 200,000 bitcoins, reportedly worth around $116m (£70m) from the old digital wallet from 2011, the exchange noted in its filing.
Mt Gox chief executive Mark Karpeles said: "MtGox had certain old-format wallets which were used in the past and which, MtGox thought, no longer held any bitcoins."
The company said in a statement: "On March 7, 2014, MtGox Co., Ltd. confirmed that an old format wallet which was used prior to June 2011 held a balance of approximately 200,000 BTC."
However, the 200,000 bitcoins were moved from online to offline wallets on March 14-15 citing security reasons.
"These bitcoin movements, including the change in the manner in which these coins were stored, had been reported to the court and the supervisor by counsels," it added.
Recently, Mt. Gox updated its website to only allow its consumers log in to their accounts and verify the balance in their digital wallets.
The latest move comes after the exchange filed for bankruptcy protection at the Tokyo District Court noting it lost 750,000 of its customers’ bitcoins, together with 100,000 of its own.
