Fiat is manipulated by governments/banks to control & have power. Whales heavily manipulate crypto. By switching to crypto, isn't it just handing the control & power from governments/banks to a small group of wealthy whales?
Fiat is not entirely manipulated by government just for control and power. That idea is very narrow. You should think that in general, fees or I guess let us put as charges for any transactions to happen. It is like a key in order for some things to function.
Compared to cryptocurrencies, we can't justify which is better considering its acceptance in the society.
It makes it more convinient.
