Digital currency (digital money or electronic money or electronic currency) is a type of currency available only in digital form, not in physical (such as banknotes and coins). It exhibits properties similar to physical currencies, but allows for instantaneous transactions and borderless transfer-of-ownership.
Examples include virtual currencies and cryptocurrencies or even central bank issued digital base money. Like traditional money, these currencies may be used to buy physical goods and services, but may also be restricted to certain communities such as for use inside an on-line game or social network.
Digital currency is a money balance recorded electronically on a stored-value card or other device. Another form of electronic money is network money, allowing the transfer of value on computer networks, particularly the internet. Electronic money is also a claim on a private bank or other financial institution such as bank deposits.
According to the Bank For International Settlements Digital currencies report of November 2015. Digital currency is an asset represented in digital form and having some monetary characteristics. Digital currency can be denominated to a sovereign currency and issued by the issuer responsible to redeem digital money for cash. In that case, digital currency represents electronic money (e-money).
As such, bitcoin is a digital currency but also a type of virtual currency. Bitcoin and its alternatives are based on cryptographic algorithms, so these kinds of virtual currencies are also called cryptocurrencies.
Digital versus traditional currency
Most of the traditional money supply is bank money held on computers. This is also considered digital currency. One could argue that our increasingly cashless society means that all currencies are becoming digital (sometimes referred to as electronic money), but they’re not presented to us as such
