you should try Bisq first before you are coming to a final conclusion and see for yourself if you actually like it or not.
it is a true DEX, has TOR inbuilt, and is better than trading in a browser. no malicious little plugins, no phoning home, sneaky ref links or other hidden shit.
it is basically an all-in-one trading software (unlike just any other mobile crypto app).
there were some ideas to start local market-making activities for the VND/BTC market and test the face 2 face feature (localbitcoins style).
but then global health problems put things back in the box of cool ideas...

it could be a cool thing to test more in the community i would say.
