This question is not appropriate because Bitcoin was created and has proven itself in the midst of extraordinary economic problems that made people distrust the existing system at that time and until now Bitcoin still holds its value unchanged. What people fear about economic collapse is the decline in the value of the currency and again I say Bitcoin is able to maintain that which we call the best hedge.
I don't agree that no matter what happens, bitcoin will still stand strong. There are situations where bitcoin will be affected too. I'm not saying it will become worthless, but it will be affected. A bloody world war might take bitcoin to below $10k. A cyber-terrorist attack may even affect bitcoin too. Of course, I'm speaking hypothetically, but the point is, that we really do not know what will happen tomorrow and saying nothing that causes an economic collapse can affect bitcoin is not very accurate.
The same thing that made the currency collapse can make bitcoin collapse.
If you direct an economic collapse due to an event like a world war, of course the price will drop because people only think about their lives without caring about anything else.
The only war between two countries that has happened recently has caused the market price to drop, although it was not severe and not for long.
It is not about that, but how long Bitcoin survives that makes us dare to say that Bitcoin can survive as long as its users are still there and it is not about the price of Bitcoin but its value.
