No fiat currency has suffered such a crash.
I don't recall any fiat currency rising from zero to $1200 either.
you should see the initial value of the first fait currency it was probably very high, because there were a strong demand for something that could get rid of barter altogether
bitcoin is like that it is comparable with the first launch of fiat, then "altfiat" come in to play, and fiat become overall stable, it is happening again but with crypto coin
