I believe in Fiat because it will always be protected by the government. Fiat is a way of controlling people, so it will never disappear
Yeah right, we have to admit that using bitcoin is still limited and has not been widely used for direct transactions. I hope many places approved bitcoin, so that it can reduce the fiat money.
I believe that will not happen easily, bitcoin is not at its peak now despite breaking the all time high, we need more time to see a massive increase of adoption but that increase is not a big threat to replace the fiat system. Bitcoin will always be a substitute money or commonly known as payment system for online transactions.
