Crypto currency

Digital currency or digital money or electronic money is distinct from physical (such asbanknotes and coins). It exhibits properties similar to physical currencies, but allows for instantaneous transactions and borderless transfer-of-ownership. Examples includevirtual currencies and cryptocurrencies.[1] 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.[2]

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 theInternet. Electronic money is also a claim on a private bank or other financial institution such as bank deposits.[3]

Digital money can either be centralized, where there is a central point of control over the money supply, or decentralized, where the control over the money supply can come from various sources.
