@kkarhan Thanks anyway; I don't see this as an endorsement, financial advice, etc.
Coincidentally I also heard of them (through their app on F-Droid). I would still need to figure out what exactly that is and how it works; on the first sight it looks similar to Bisq (for :bitcoin:), but more centralised.
(Also, I hope you don't mind that I @-ed you. Usually I don't do it; I only did it since you enthusiastically used the hashtag.)
