The dollar crashed 30% in the 2000s (and the 80s, and the 70s, and probably the '10s). Soon it will be because of trade wars and losing value to the euro and the yuan though.

To your point, remember when the crypto market had a net loss of almost 3000 points in a single day in March 2020?! Oh wait, that was the Dow, sorry.

So you don't trust the stock market or the assets that back it either, do you? It swings 10% or more some days!
