I appreciate your concern, but no need to worry. All I do is buy on Robosats. I think I posted before about how I do think it's important for there to be a robust p2p bitcoin exchange. That's the only way to fight centralized exchanges like coinbase. It's hard to envision a really liquid market that doesn't have buyers and sellers using all types of assets, including fiat. Personally I can't bring myself to use fiat on p2p. That's why I'm stuck buying with physical gift cards. But, if there aren't traders willing to buy and sell everything as bitcoin market makers we're never going to have enough liquidity to make coinbase, Gemini, etc obsolete.
