Tokyo-based cryptocurrency exchange Coincheck has verified that it has suffered what shows up to be the biggest hack in the background of the technology.
In a press conference at 23:30 JST (14:30 UST), the exchange’s president Wakata Koichi Yoshihiro and chief working officer Yusuke Otsuka approximated its loss at 58 billion yen (approx. $533 million). According to Bloomberg, which went to the meeting, 500 million NEM tokens had been used from Coincheck’s digital wallets.
Twitter posts by Nikkei appeared to indicate that the precise quantity stolen might not end up being fully known until further investigations have got been carried out into the intrusion.
But though the exact dollar shape for the incident is hard to pin down (given the volatile character of cryptocurrencies and the company’s absence of information), data suggests the shape is now at least over $400 mil, factoring for a decline in the worth of XEM, the NEM protocol’s symbol, following the incident.
At press period, the price of XEM was $0.85, straight down from a high of $1.01 today, according to data from Coinmarketcap.
Particularly, the buck amount stolen from Coincheck can be most likely greater than the quantity stolen from Mt. Gox in 2014 (chosen at $340 million), though the impact on the cryptocurrency market will be very much smaller sized provided the enormous increases in marketplace capitalization since.
Rumors had been circulating about the theft since early this morning hours when Coincheck abruptly froze the majority of it is services.
The firm announced on its website around 13:00 JST (04:00 UTC) that it had restricted deposit, trading and withdrawal of XEM, the token running on the NEM blockchain.

In the pursuing hour, trading of all cryptocurrencies was also limited, except bitcoin. Relating to the most recent update, other deposit strategies including credit cards have also been halted.
