Japan’s hacked crypto exchange Coincheck bought out

AFP:  Japanese online broker Monex Group said yesterday it would buy virtual currency exchange Coincheck, which was hit by a massive hack that saw thieves steal hundreds of millions of dollars in virtual currency.

The decision came after Coincheck refunded more than US$440 million to its 260,000 customers who lost their holdings of NEM, a leading cryptocurrency, following the hack.

Thieves siphoned away 523 million units of the virtual currency from Coincheck -- then valued at US$547 million during the January hack, thought to be one of the biggest ever.

Monex said in a statement it would acquire all of the 1.78 million shares of Coincheck for 3.6 billion yen (US$34 million). 

The broker added: “We aim to build a secure business environment for customers by fully backing up Coincheck’s enhancement process” after authorities ordered improvements following the hack.

Coincheck chief executive Koichiro Wada and chief operating officer Yusuke Otsuka will step down and Monex managing director Toshihiko Katsuya will take over the CEO post.

Japan’s Financial Services Agency last month ordered five cryptocurrency exchanges, including Coincheck, to make improvements to their business operations, while slapping two exchanges with suspension orders.

Yesterday, the FSA imposed fresh punishments, ordering Yokohama-based FSHO to temporarily halt operations for two months -- partly for not establishing a system for risk management despite the FSA’s instructions. 

The FSA also ordered the “Eternal Link” exchange to suspend operations for two months and issued an improvement order to a Tokyo-based exchange known as “Last Roots.”

The Coincheck theft exceeded the US$480 million in bitcoin stolen in 2014 from another Japanese exchange, MtGox.

That hack in 2014 prompted Japan to issue new regulations, requiring exchanges to obtain a government licence, but Coincheck was allowed to continue operating while the FSA was reviewing its application.

In February seven plaintiffs -- two companies and five individuals -- filed a lawsuit against Coincheck seeking the reimbursement of 19.53 million yen in lost virtual currency and further compensation for interest lost due to the hack.

Japan is a major centre for virtual currencies and as many as 10,000 businesses in the country are thought to accept bitcoin.
