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?

It would be good, yet still nothing more than a dream. I still need to convert Bitcoin or Ether to fiat on a daily basis with my Wirex or Fedor cards to cover my expenses and pay everywhere.
People doesn't changes and this is the main reason why crypto will not be widely adopted in next 5-10 years. Like it or not, we will depend on exchanges, not necessary banks.
