I have no doubt a lot of people have made real money with crypto. By any definition, however, any crypto is the “fiat-est” of fiat currencies.
No thanks
There are two meanings of the word “fiat” that are both implied when people refer to fiat currencies.
The first meaning is “faith”, as in, not redeemable for a standard unit of a commodity at a bank. I agree that crypto meets this definition.
The second is “at the stroke of a pen”, i.e. that more currency may be produced at will and without limit. Crypto does not meet this definition.
The US dollar satisfies both definitions, though.
