Cryptocurrency is different from fiat currency in a few key ways. Firstly, cryptocurrency is not issued by any central authority and is instead created through a process called ‘mining’. Secondly, most cryptocurrencies are decentralized, meaning that they are not regulated by any government or financial institution. Finally, cryptocurrency transactions are secured with cryptography and are processed peer-to-peer, making them less vulnerable to manipulation, fraud and other activities that can affect fiat currencies.
