When a huge global financial crisis happens it just happens to everyone, there is absolutely no way of running from it.
Stocks will fall, crypto will fall, gold will fall, house value will fall. There will be nothing that will profit you at the time of an economical crisis, you will lose money no matter what you are invested into. There is no running away from this at all. Hence there is absolutely no way of profiting neither.
In the end crypto is used to the volatile world whereas other methods take years to recover so the best move you can make is stay on crypto and take the hit and just hope that you will win the recovering race compared to other investment methods.
I still prefer diversification and putting my money into multiple stuff but in the end none of that matters during a huge global crisis.
