The theft of over $500 million in cryptocurrency from the Japanese stock exchange

One of the largest Japanese crypto stock exchanges, Coincheck said on Friday that about $535 million in NEM crypto coins were stolen from hackers. Exchange management said it had kept the coins in a virtual portfolio.
The stolen coins were worth about 58 billion yen.
Hackers have stolen less popular cryptocurrency from the main Japanese exchange, worth hundreds of millions of dollars on Friday.
Nearly 523 million NEM coins were transferred to another account at around 3 am local time, according to data from the Japanese stock exchange. Coincheck accounts for around 6% of the yen cryptocurrencies trade, ranking fourth.
The NEM is designed to help businesses process a database. It fell momentarily by over 20% on Friday before finishing the day with a fall of about 10% to 85 cents.
The Japanese stock exchange has announced it does not seem like hackers have stolen other key cryptocurrencies.
Just to recall that in December, South Korea's Youbit lost 17% of its digital assets, prompting the parent to declare bankruptcy.
In 2014, the Tokyo Exchange Mt. Gox also went bankrupt after announcing that they had lost 750,000 of the bitcoins of their clients, as well as 100,000 of their own.
In mid-December, the US investment bank Morgan Stanley predicted that $630 million worth of bitcoins will be stealed from hackers.
