I also had a conversation with their ambassador on Twitter. He defended them without any arguments—he send me just memes, when I sent him evidence and arguments .
I gave up , waste of time.
Anyway - Do you know any good alternatives to play poker with crypto/BTC?
If not, I guess I’ll just go back to Web2 poker

Unfortunately there aren't many. Nothing I liked at least. I played a ggpoker for a while cause they also take btc and usdt and so on, but it gets converted into usd and of course there is KYC and so on. Also the withdrawal can take some time and you need to provide "significant action" before you can withdraw, basically a rollover.
Just never play at nitrobetting or whatever they call themselves now. Full of collusion, bots, huge rake and low player numbers.
