It is said that bitcoin will destroy the fiat system but i believe that if this happens the world will change completly because banks and a lot of things will go out of market.
It is so hard to change the fiat system, im really sure of that. Okay, bitcoin is stronger each day, but to change and replace the fiat system, i guess it won't. You don't need to believe and accept all of the expert says, i know this is a word you heard or read from news from that person, i kinda forgot the name. Even though there are already country that accepts bitcoin as a legal payment, some others banned it. Some people knows bitcoin well, some others doens even heard of bitcoin. But fiat system, every country uses it, every person knows and uses it, and with it we measure the amount or price of products or things in this world. So, to change a fiat system,it is unlikely, but if you talk about will bitcoin be used by everyone by 2022, it has a chance, because like i said, bitcoin is growing more and more, so there is a chance that bitcoin will be used by people along side the fiat system. That is what i thought.
