Payment is made through smartphone applications, and when customers read a QR code with smartphones, it is settled in the virtual currency equivalent to the Japanese yen bill.

A woman from a 20-year-old company employee who had traded NEM by coin check for this leakage problem said, "Although I was not running out, the coin check has low security risk If I think about doing it, I think that I did not spill and I think that improvement is necessary. "

Also, a man in his 30s who is self-employed who has a virtual currency other than NEM said, "I was surprised that the spill amount was large, I think the coin check should raise the priority for security On the other hand, because it is an unmatured industry, users themselves need to think about safe management of currencies.
