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?
As i think, fiat is always better than crypto like btc. Fiat may controlled by government/banks but quite impossible to drop value of 10% within a day 
when it's possible to drop btc price anytime, even 10% within a day.
