I've used Centralized no KYC exchanges for several years now.  I like using them because they're simple, quick and impartial.  No login, no account, no password.  Never used them for deceit or crime.

I know who the devs of some of them are (maybe not personally, but I know of them and their reputations) so I'm not worried about losing my coins but I don't swap huge amounts (God forbid I ever did lose my coins).

I've never swapped for the same coin.

Been using Sideshift.ai since 2019
