At that point if the crisis is as big as some people imagine it will be irrelevant if billions of dollars or even trillions of dollars come to the market, because at that point fiat currencies will be crashing so hard that people are going to try to find a currency any currency that is not crashing and since bitcoin is going to be one of them we could basically ask for anything we wanted for our bitcoin and people will have to pay it if they do not want to lose everything.

It is weird that people do not take precautions in the case something like that happens but most people do not really care about the future and prefer to deal with problems until those problems present themselves, which is the wrong way to approach something as important as your financial well being.
