What

Cryptocurrency, also called digital currency, is a highly decentralised currency or means of transaction between people (peers or business partners) which gets confirmed in a public ledger via a process known as mining. Cryptocurrency is a form of digital money that’s designed to be secure and, in many cases, anonymous. A defining feature of a cryptocurrency, and arguably its most endearing allure, is its organic nature; it is not issued by any central authority, rendering it theoretically immune to government interference or manipulation.
