Two different questions hide in that one. In a liquidity panic the first move is usually down, together: March 2020, bitcoin fell with everything, because people sell what they can to raise dollars. So contagion wins the first days. That is not bitcoin being weak, it is that most people hold it somewhere they can be forced to sell.
The second question is what you still have afterward, and there the difference is custody, not price. On an exchange a crash is a price event and an access event. You watch the number, then find out whether the door opens. Celsius was exactly that. If you hold your own keys, it is only a price event.
Will capital rotate in later? Real case, but treat it as a candidate, not a fact. It is a bet that survives a crash, not protection during one. A key is not a vault.
Plain 5-minute version for people who never held a key, risks left in:
