Imagine living your life without depending on Banks ever again. Using only cryptocurrencies such as Bitcoin or Ethereum, you can make your own income stream and use the coins earned to buy stuff from merchants who accept them. Every day, cryptocurrencies have been going closer towards full mainstream adoption. However, there are still some things which prevent crypto from being used over traditional payment systems we've been accustomed to for a long time.
Nonetheless, what's it like to live only on crypto instead central-bank issued fiat money?

Having the chance to live in a world where crypto alone exists without any presence of banks would promote greater convenience and an assured control of your money. Though we cannot really testify how successful and beneficial to all, if we are going to observe and analyze properly how the system works, we can atleast be more confident that the world would have a better monetary system with it.
Very well said, living without the banks, fiat, and instead use cryptocurrency might backfire to us. I mean cryptocurrency and fiat, in my opinion, both live in a harmonious way that benefits us in their own ways. It is scary and exciting at the same time thinking of using cryptocurrency all of the time without any banks that secretly robbing people's money, however, I guess it is too early for this to happen.
