As a trader, do you feel safe using such exchanges that haven’t released theirs or should the more transparent ones be given preference?
I don't really care about it because prior to FTX collapse, no one really care about proof of reserves. The thing is, if an exchange is going to collapse, proof of reserve will have little to no effect on such an event (my personal belief) so this is why I'm not too big on exchanges declaring their proof of reserves as it could be faked since most of those reserve assets are not publicly available on-chain plus there's plenty of moving parts with this sort of things. Definitely a "nice to have" attribute but not the ultimate decider for me
