Hi @jennus5. Welcome to t̶h̶e̶ ̶r̶a̶b̶b̶i̶t̶ ̶h̶o̶l̶e̶ Bisq.
It is practically impossible to get scammed as a buyer. Tainted BTC are rare on Bisq and kinda rare in general since any form of tainting can be negated with CoinJoin, mixers etc. Still, there is always a way for you to check if the seller is selling tainted BTC.
Click on the i button next to SEPA (COUNTRY_CODE)
In the pop up that appears, click on the link next to Maker fee transaction ID
You will get to a transaction that contains the trade deposit and the maker fee. You can use this info to track the BTC trail for the trade. To do this, you need to know:
Never heard of globally tainted BTC.
Likely exchanges maintain their own lists of tainted btc addresses but dont share them publicly. And indeed, mixing and other coinjoin techniques makes them untainted anyway.
As a new btc buyer your issue will probably be the 0.01 buy limit.
Wondering how one would filter “sellers with a history of large trading volume” as only account age is available ?
