Mt. Gox Kept Trading After Discovering Lost Bitcoins

Mt. Gox Co., the bankrupt Bitcoin exchange, allowed customers to continue trading the virtual currency for more than two weeks after discovering it had lost “hundreds of thousands” of Bitcoins.

The company halted all withdrawals on Feb. 7 upon finding it had lost Bitcoins owned by customers and itself. Trading continued until Feb. 24, when an internal investigation put the number of lost Bitcoins at 744,408, Chief Executive Officer Mark Karpeles said in a sworn statement filed in U.S. Bankruptcy Court in Dallas on March 9.
