What is the main purpose of cryptocurrency?

The primary purpose of cryptocurrency is to overcome the issues with the fiat currencies by decentralizing the finances and putting the power solely in the hands of the currency holders. By doing that the powers that are held by the governments and the financial institutions will be nulled that can solve problems like inflation and agency charges.

Another main purpose of cryptocurrencies is to give people the opportunity to earn money, I think so! Because we can earn from home by trading cryptocurrencies or by investing in cryptocurrencies even if we are on the bed. I'm saying this because crypto has changed my life since I joined it in 2017 and I'm just working at home.
