To me the crypto is a virtual currency that is an alternative currency that is decentralized. This means that there is no writing of the governing party. Therefore Crypto value can not be used in case of change caused by central bank. Crypto value is determined by enthusiasts, supply and demand in the market, such as gold with other precious metals.
Crypto is managed by a peer-to-peer technology network whose implementation depends on cryptographic principles to validate transactions and the generation of the currency itself. Crypto can also be a form of currency that is calculated or math only. Different paper currency or metal coins are in print.
