Missing bitcoins apparently found in an 'old-format' wallet previously thought to be empty
The defunct Bitcoin exchange, which last month filed for bankruptcy in Japan after losing close to 850,000 bitcoins (including 100,000 of its own) to a "bug in the Bitcoin system," now says it recently found 200,000 bitcoins in an "old-format" wallet previously believed to be empty.
"MtGox Co., Ltd. had certain old-format wallets which were used in the past and which, MtGox thought, no longer held any bitcoins. Following the application for commencement of a civil rehabilitation proceeding, these wallets were rescanned and their balance researched. 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 (199,999.99 BTC)," CEO Mark Karpeles announced in a statement (PDF) on Thursday.
"MtGox Co., Ltd. investigated the presence of these 200,000 BTC, immediately reported it to its counsels in the application for commencement of a civil rehabilitation proceedings ("counsels")," he further wrote, adding that the counsels duly notified the court about the development on March 10.
The court, according to the statement, has also been made aware of the fact that, for "security reasons," the erstwhile largest bitcoin exchange first moved the 200,000 BTC to an online wallet the very day they were discovered and then, between the 14th and the 15th, to offline wallets.
Not everyone is convinced, least of all the law firm handling a class action lawsuit against the defunct exchange in the States.
"Today in court we got relief ... specifically to track the 180,000 bitcoins, which we've been monitoring. Hours later, Mt. Gox claimed it 'found' these bitcoins ... it appears Mt. Gox realized we were close and decided to acknowledge that it owned these 180,000-200,000 bitcoins," Steven L. Woodrow, a partner at law firm Edelson, told Reuters.
"The idea that there were 200,000 or 180,000 bitcoins in a single wallet that they just discovered which had been dormant for years that contained 180,000 bitcoins is undercut by plain evidence on the blockchain."
