Japanese prosecutors seek 10 years jail time for former bitcoin exchange MtGox's CEO on embezzlement charges
- French national Mark Karpeles, 33, is accused of fraudulently manipulating data and pocketing millions of dollars’ worth of the virtual currency
Tokyo prosecutors on Wednesday demanded a 10-year jail term for the former head of collapsed bitcoin exchange MtGox, local media reported.
French national Mark Karpeles, 33, faces charges that he fraudulently manipulated data and pocketed millions of dollars’ worth of the virtual currency.
The Tokyo-based exchange – once the world’s biggest for bitcoin – collapsed in 2014 after cryptocurrency worth half a billion dollars disappeared from its virtual vaults, a mystery that remains unsolved.

Karpeles faces charges that he embezzled about 340 million yen (US$3 million) and altered other data related to MtGox. The trial against him began last July.
But those charges are not directly related to how MtGox lost 850,000 coins – worth about US$480 million at the time.
