Digital currency is different. It is essentially a piece of data, but it is encrypted by an extremely complicated algorithm. It has the characteristics of traceability and tamper resistance, so it is also called cryptocurrency. Bitcoin is a typical example.
However, there are also views that money should be issued by national credit endorsement, so Bitcoin should not be called digital currency, but should be collectively referred to as token with ETH, EOS, etc. But in order to facilitate everyone’s understanding, these tokens will be called digital currency in this class.
