I don't think Fiat will ever be destroyed because the world becomes digital Fiat will remain because it is But the mixture of fiat and crypto isn't an equivalent Some differences exist between the 2 But the virus features a detrimental effect on the 2. The crypto market has grown tons since then But Fiat is slowing down day by day. it's under the control of the govt and it improves with the economy of the country But crypto has nothing to try to to with the virus or the economy of the country.
there are high chances that we won't see fiat same as it is right now in the next decade.
however I do not believe it will be btc or eth or whatever there is on top of cmc right now.
It will be digital govs backed financial instrument, basically d-usd.
