remembering the FTX case, a good and reliable exchange could become a bad exchange in just matter of short time.
so just trusting the same exchange for too long might also pose risk if suddenly things goes south, I'd think that diversification of asset through various "trusted" exchange as something that's truly necessary.
I personally also try to seek the most trusted exchange there is but honestly, i'm not risking my money to be in the same situation as FTX, waiting so long to get reimbursement is such a pain in the ass, that with a big "IF" our money even get reimbursed in the first place, things can get messy. it's okay to keep trusting exchange but also on the lookout for the impending doom, to avoid being the victim.
Most people agree that it's best to use just 1 exchange for reasons like consistency, routine, and ease of management...but I'm of the same mind as you. Indeed, risk is all around us and diversification is essential. We often advise each other to diversify assets, whether it's gold, bitcoin, or real estate...even the best assets have risks. Or even when protecting the seed phrase, we always have 2 or 3 backups to minimize the risk. So why do we only use 1 exchange when it is already risky because it is a centralized platform?
Regarding privacy, once we have used one or more exchanges, our privacy will no longer exist. What guarantees that the exchange we are using does not sell our personal information to 3rd parties?
Even the banks, schools, and services we use every day are silently collecting our data and selling it. There is only one way to ensure privacy and that is to not use any centralized exchanges or platforms.
