Tokyo's crypto-exchanger Coincheck will return 90% of stolen $ 400 million on Friday

The Tokyo Coincheck Exchange will return the affected users 46 billion yen from 58 billion yen (more than $ 400 million) stolen as a result of a hacker attack last week.

Theft became possible, as Coincheck kept NEM tokens in a "hot purse" instead of a safer "cold" one. The reason for this management of the crypto-exchange was the lack of personnel and technical difficulties.

According to the official statement of the company, 260000 owners of NEM wallets, which became the object of attack, will receive compensation. The timing and mechanism of reimbursement are still under development.

The Coincheck exchange itself may be subject to administrative punishment in accordance with the legislation on financial settlements.

Meanwhile, the Financial Services Agency of Japan (FSA) sent a few dozen companies working with cryptocurrencies notices about the risk of new cyber attacks and the need to strengthen protection.
