Creditors of bankrupt Bitcoin exchange Mt. Gox have until Nov. 28 to file proof of their claims, according to a notice from its trustee, PCWorld.com reported today. Attorney Nobuaki Kobayashi, the court-appointed bankruptcy trustee for the Tokyo exchange, posted a notice on the Mt. Gox website Wednesday with details of the liquidation procedure. Creditor claims will be examined starting Feb. 25, 2015, nearly a year to the day after Mt. Gox went bust with liabilities of ¥6.5 billion ($63.6 million). Creditors could include hundreds of thousands of users who deposited bitcoin with the exchange. When it collapsed, Mt. Gox said nearly half a billion dollars’ worth of bitcoin was unaccounted for and that hackers had exploited a software problem.
