The amount of Bitcoin stolen from DMM Bitcoin is 4,502.9 BTC. This is the largest Bitcoin leak incident in Japan. At the time of writing, it is worth about 66.2 billion yen.
After the Bitcoin leak, DMM Bitcoin raised 55 billion yen through borrowing and capital increases from group companies. It quickly raised the equivalent amount of Bitcoin that was stolen. However, there was no prospect of resuming service after that, and in September, the Financial Services Agency issued an order to improve business practices.
The Financial Services Agency pointed out that DMM Bitcoin had flaws in its cryptocurrency management system, saying that "a system has not been established to properly and reliably carry out cryptocurrency exchange business." It then instructed the company to strengthen its system risk management system and to establish a system to properly respond to the risk of cryptocurrency leaks.
In this situation, DMM Bitcoin decided that it would be difficult to turn its management around and went out of business.
