Red Button procedure for crypto wallet

Hi guys
I was searching if it is already documented, or specific procedure for the following need : let say you got a dozen of crypto tokens stored on a specific exchange (binance or coinbase or other).
If suddenly, a massive crypto crash occurs (Bitcoin crash down followed by other AltCoins), concretely, what I should do !?? convert ASAP all my coins to USDT token for example ? or cashout/withdraw all my tokens to my bank account ?
Thanks a lot for your feedback

You should not remove investment at time of crash. You should consider adding more of good coins when price falls below by good margin.

Hi, Yes I fully agree about this thing, but I was more considering the following event : we are aware that this or this crypto token is going to crash, at this specific time its better to withdraw or switch to a stablecoin USDT you are agree yes ? and then charge again our bag when the token is at the bottom of the dump. in this situation, what is recommended ?

Whos said that crypto is going to crash ? It is not going to happen anytime soon seeing the past performance.
