TOKYO — A Japanese exchange has lost 58 Billion Yen ($530 million) in cryptocurrency because of hacking, according to Japanese media reports.The Coincheck exchange said on its website Friday that it had halted sales and withdrawals of the currency, which is called NEM ,10th cryptocurrency by market capitalisation. After the exchange suspended deposits and withdrawals, NEM plunged more than 16 percent in a 24-hour period, according to CoinMarketCap . It later added that it had restricted dealings in most other cryptocurrencies too.

At a Friday night news conference, Coincheck President Koichiro Wada bowed and apologized. He said the company may seek financial assistance, according to Kyodo News service. Japanese TV footage showed a small group of customers standing outside the company’s Tokyo head office Friday night.
Coincheck, which calls itself the leading Bitcoin and cryptocurrency exchange in Asia, said it detected the unauthorized access to its system about 3 a.m on Friday.
In 2014 major Tokyo-based bitcoin exchange MtGox collapsed after admitting that 850,000 coins -- worth around $480 million at the time -- had disappeared from its vaults.
