What is a cryptocurrency?
A cryptocurrency is basically a medium of exchange stored on blockchain built on cryptography. It is a digital peer to peer currency i.e. it is a decentralized form of currency. How it differs from the regular currency is that, banks keep a record of all the transactions and manage the database, whereas in this every peer keeps a record of all the transactions and is the one the transaction between two is verified then this is added to a block in the blockchain which can then never be altered and is permanent.
