The Japan Financial Services Agency recently published information on the relevant meeting of the "41st Financial Review Conference" held last month. Kyoto University professor Iwata went straight to the meeting and said: When the price of Bitcoin is relatively stable, it can be used for international transactions, including money laundering and other illegal transactions. However, when the price of Bitcoin fluctuates significantly, it cannot be used as currency. I don't think the current bitcoin should be called virtual currency. On the other hand, it is also possible to have a currency more suitable for being called a virtual currency in the future. In this case, whether a new cross-border system will emerge and how it should be dealt with will also need to be studied.
