If an economic crisis emerges and the value of fiat currency plummet I believe people will convert their currency to Bitcoin to preserve its value. With funds flowing into Bitcoin I think this will be the time when the golden years of Bitcoin will happen. We can possibly see the price of Bitcoin increase to an unimaginable height.
When an economic crisis occurs, not only does the value of fiat plummet, but speculative assets also plummet as people tend to seek safer assets. Therefore, that is only true if people consider bitcoin a safe haven, but the opposite if they still consider it a speculative asset like what is happening. It will be dumped and lose value rapidly, instead of increasing in value as you think.
So far, gold is the only safe haven asset and bitcoin is classified as a speculative asset, but hopefully this will soon change as bitcoin matures.
