Exchange market can't guarantee with trusted place for saving assets after FTX exchange collapse, I think another exchange just waiting moment become crash and collapse like FTX exchange. I agree with you without hold assets in exchange market but for daily trader can't for holding assets in hardware wallet. I am thinking about with my local exchange will collapse like FTX exchange because almost my assets holding in local exchange market.
I aware when holding assets in hardware wallet because want to earn daily day profit take longer time for withdrawing and deposit fund from exchange to hardware wallet or on the contrary.
currently, an important topic in crypto is about trust, user trust is finally undermined by the FTX event which of course has a significant impact on crypto, not only from the price but the level of trust in centralized markets eventually decreases. Storing on a centralized exchange won't be safe either. As a day trader making regular withdrawals to a personal wallet it would be better than having to hold them on a centralized exchange
