Cryptocurrencies fall after hack hits Japan’s Coincheck

Cryptocurrencies

TOKYO: Cryptocurrencies fell Friday after Japan-based digital exchange Coincheck suspended client deposits and withdrawals for virtual currencies except bitcoin, saying it had been hacked.

Coincheck said it was investigating “unauthorised access” of the exchange that appeared to result in a loss worth half a billion US dollars of NEM, the 10th biggest cryptocurrency by market capitalisation.

“At 3 am (1800 GMT) today, 523 million NEMs were sent from the NEM address of Coincheck. It’s worth 58 billion yen based on the calculation at the the rate when detected,” said Coincheck’s chief operating officer Yusuke Otsuka late Friday.

“We’re still examining how many of our customers are affected,” he said, adding that the exchange was trying to find out whether the breach was from Japan or another country.

After the exchange suspended deposits and withdrawals, NEM plunged more than 16 percent in a 24-hour period.

Major virtual currencies had rebounded slightly by late Friday but were still down, with Bitcoin dropping 2.13 percent to $10,987.70, ripple sliding more than six percent and ethereum flat.

Coincheck said it had discovered the breach at 11.25 am and announced it had suspended trading for all cryptocurrencies apart from bitcoin in a series of tweets.

According to its website, which proclaims it is “the leading bitcoin and cryptocurrency exchange in Asia”, Tokyo-based Coincheck was founded in 2012 and had 71 employees as of July last year.
