American bank JPMorgan was the first among large banks to announce the release of its own cryptocurrency. According to the CNBC, the cryptocurrency released by the bank was named JPM Coin. It will be used for instant payment between bank customers. In a few months, JP Morgan will start testing this digital currency. Despite the fact that the authorities of different countries treat bitcoin differently, often considering it a financial pyramid, many banks express interest in creating their own cryptocurrency. Thus, Japanese bank Mizuho Financial Group plans to launch its cryptocurrency in March.
