Coincheck halted operations after the hack and prevented traders from withdrawing their virtual currency from the exchange -- a decision that left those assets in limbo while the cryptocurrency markets continued to move. "Plaintiffs are demanding Coincheck return their cryptocurrencies -- 13 different kinds including NEM," Mochizuki said. On Tuesday, Coincheck said it had resumed operations for withdrawals denominated in Japanese yen but has still frozen withdrawals of a dozen different kinds of cryptocurrencies. Thieves syphoned away 523 million units of the cryptocurrency NEM from Coincheck during the January 26 hack, exceeding the $480 million in virtual currency stolen in 2014 from another Japanese exchange, MtGox. That hack prompted Japan to issue new regulations, requiring exchanges to obtain a licence from the FSA, but Coincheck was allowed to continue operating while the agency was reviewing its application.
