#EthereumFuture Digital currency is a financial balance recorded electronically on a stored value card or another device. Another form of electronic money is network money, which allows value transfer over computer networks, particularly the Internet. Electronic money is also a claim on a private bank or another financial institution like bank deposits.

Digital money can be centralized, where there is a central point for the money supply, or decentralized, where the money supply can be controlled from different sources.
