I recently watch a lot of advertisements for virtual currency on TV in Japan.

Japanese firtst-class entertainers are in the advertisements.

It is said that the value of virtual currency has jumped up ten to twenty times from the original value in the last few years.

I'm interested in investment in virtual currency as well as many Japanese, but hackers stole a reported $660 million  virtual currency from Coincheck, one of the largest exchanges last month.

Such an incident makes me anxious, and I hesitate to buy them.
