hello everyone, this question was a great question,i don't really known much about cryptocurrency but i will say the little i know.

the first fact about cryptocurrency and fiat is that they have value than each other, the value of cryptocurrency is higher then the value of fiat.

fiat itself doesn't have any value,the reason is that it is something you can see with anybody, it is what you can see anywhere, and their is nothing you see with people everyday,everywhere, anytime that will have value any more ,that is why fiat fall.

it's not cryptocurrency didn't fall but the rate that fiat fall is higher then the rate that cryptocurrency fall,right now thousands of people invest on crypto became it also save their money.

in conclusion,fiatcurrency is always printed everyday and the value for fiat decrease almost every time.thanks
