Yes, it requires KYC but do we have a better option to trade smoothly with lots of pairs and make different kinds of investments? I use CEXs because they are easy and fast, I can use them on my iPhone and MacBook.
You can use Bisq on your MacBook. You cannot use it on your iPhone. Sounds to me like you want to trade regularly (i.e., in the middle of the day) and for altcoins that exist in CEX. Bisq is not best for using regularly within the day, and it certainly contains no shitcoins!
However, for those who often trade through DEX, there is a certain amount of risk that their data will still be leaked to unknown people, because (if I'm not mistaken) if we sell cryptocurrency we have to provide our name, surname and bank account number (maybe even our address). If we are not skilled enough to hide how many coins we actually have, it is possible that someone would choose their targets for physical attacks in this way.
I use Revolut. The other party only knows my revtag. I don't give full name, nor address, and that information cannot be derived from the revtag, unless Revolut experiences data breach.
