One of Japan’s biggest cryptocurrency exchanges said that about $400 million in NEM tokens were lost after the coins were sent “illicitly” outside the venue, spooking investors in a country that’s still wary of digital-token exchanges four years after the collapse of Mt. Gox.

After hours of speculation, Coincheck Inc. co-founder Yusuke Otsuka said during a late-night press conference at the Tokyo Stock Exchange that the company didn’t know how the 500 million tokens went missing, but the firm is working to ensure the safety of all client assets. Coincheck said earlier it had suspended all withdrawals, halted trading in all tokens except Bitcoin, and stopped deposits into NEM coins.
