"Cryptocurrencies slumped after one of Japan’s biggest Bitcoin venues halted client withdrawals, spooking investors in a country that’s still wary of digital-token exchanges four years after the collapse of Mt. Gox.
Coincheck Inc., based in Tokyo, said in a series of tweets that it had suspended all withdrawals, halted trading in all tokens except Bitcoin and stopped deposits into NEM coins, without explaining why. When reached by phone, an exchange official wouldn’t provide further details and didn’t respond to a subsequent emailed request for comment. Additional calls to Coincheck went straight to voicemail.
NEM, the 10th-largest cryptocurrency by market value, fell 15 percent in the 24 hours through 5:52 a.m. New York time, according to Coinmarketcap.com. Bitcoin dropped 6.5 percent and Ripple retreated 11 percent in that period.
