TOKYO (Reuters) – The 32-year-old chief executive of defunct Mt. Gox pleaded not guilty on Tuesday to charges relating to the loss of hundreds of millions of dollars worth of bitcoins and cash from what was once the world’s biggest bitcoin exchange.
French national Mark Karpeles filed the plea in response to charges of embezzlement and data manipulation at the Tokyo District Court, according to a pool report for foreign journalists.
Mt. Gox once handled 80 percent of the world’s bitcoin trades but filed for bankruptcy in 2014 after losing some 850,000 bitcoins – then worth around half a billion U.S. dollars – and $28 million in cash from its Japanese bank accounts.
In its bankruptcy filing, Tokyo-based Mt. Gox blamed hackers for the lost bitcoins, pointing to a software security flaw.
Mt. Gox subsequently said it had found 200,000 of the missing bitcoins.
