It is too soon to tell as bitcoin is still in its infancy stage
and has yet to become mainstream and adopted by the
public.
I don't think it will replace fiat currency in at least 10 years
or more. We still have a lot to achieve and I believe this is
only the beginning of a revolution.
the answer is pretty good, I completely agree with you. so many people think crypto can replace fiat money. but basically everyone still needs fiat money for up to 10 years to come.
