Are cryptocurrencies used in banking?

To date, not a single banking system works with cryptocurrencies officially and systematically. Several states expressed their positive attitude and readiness to create national cryptocurrencies. The list includes Japan, Belarus, Russia, and Switzerland. Cryptocurrencies can be used to make standard and p2p transactions. The use of cryptocurrencies allows you to make instant payments with minimal fees. It is beneficial for the government to create national cryptocurrencies to reduce the issuance of cash, which is quite expensive. For example, in Japan, about 70% of the money turnover is cash. So the country was one of the first to express a desire to create a national cryptocurrency.
