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?

Most of us would say it would be good, but we will never know once where already in that situation. Have you ever thought how are economy would be if our currency will be volatile since it is crypto. Or if that point comes, and crypto will be stable since it is the main currency, will people still enjoy crypto as it is today?
If we do not analyze and respond in a hurry, we will always say life with crypto is always very good when we can enjoy and enjoy the benefits of crypto every day but as you say, when we calm down and think more about that life, whether we are satisfied with the value that changes every day, salary and wage goods, and some other miscellaneous money or not. Besides, if it really maintains stability and doesn't change, we will no longer feel the biggest benefit from crypto, crypto will not be crypto
