I am very aware that Crypto provides convenience in transactions or forms of investment. But from the human side, not everyone can accept that fact. Many of those who still doubt the existence of this cryptocurrency gets the issue that it is not a recommendation for future life. To become a Crypto replacement for Fiat, I might have to give input that crypto must be recognized by the world. If that has been realized, maybe Crypto is an easier access to the fiat system and has a good future.
