I stumbled across this topic and I know this is an old one, but just in case you guys are still active and want to be private.
https://bisq.network/Bisq is the exchange you are looking for, decentralised and private (Tor integrated!).
You're welcome!

Well its more secured since it is TOR integrated but still I am in doubt about as long as it is in deep web.Though the main issue here is privacy but still Its very risky in my opinion and its better to transact on legit exchanges.
