Already the situation is clearly visible in South America countries like Argentina and Venezuela country affected due to hyperinflation now crypto is main source of transaction
It would be exciting to see how people will be reacting to Bitcoin once there can be a global crisis akin to 2008. Will they go for the real gold or Bitcoin its digital version? What we are seeing in Venezuela is that there are many people who are using it to survive buying foods in nearby countries because their own fiat money bolivar is practically worthless. I am sure that there can be a big economic crash, people will look at Bitcoin as an alternative to protect their wealth though some might be discouraged by its volatility unlike the real gold. Though we should not be wishing for a crisis but once there will be it can be worth watching how the market will do with Bitcoin.
