Almost everyone thinks a crash is coming. There has never been a crash where almost everyone has seen it coming. Therefore there will not be a crash at least in the near future. Prices might pullback but it won't be a crash.
In order for a market (that's reasonably distributed) to move in a direction, there needs to be some level of consensus. If everyone thinks there will be a crash, then there will be a crash, because everyone will sell.
Isn’t there some logical fallacy about believing that since something has never happened, it will never happen?
It's called the Black Swan fallacy. Ironically, it's what happened with the recession and housing crisis in 2008, except back then it was "the housing market isn't a bubble, people will never default on their mortgages en masse".
But everyone thinks there's a recession and crash coming now, don't they?
Bitcoin? Everyone saw that coming.
A perfect example, though it seems some here are somewhat butthurt :)
