1. Coinjoined or not. Until today there is no law that I am aware of that makes it illegal send coinjoined sats to an exchange. At least not in Brazil where I am. I‘m doing the same with more volume for a much longer time with Binance and never had a problem.
2. I guess when he answers to my post he sees my DM too, right? I‘m paying for nostr wine and I guess he is too.

Oh, and I didn’t lose any sats. As they said I had to withdraw the rest which I did. I’m bothered by the treatment as a criminal without explanation.
