You might as well start heading for the currency exchange section (or LBC, etc) and sell your BTC for fiat the way things stand right now. Crypto gambling isn't incredibly active for card games as a whole, and things likely won't change in the near future (which is a shame considering how great crypto gambling is).
I’ve seen a couple of projects announced on this board during the last months but I don’t know if they were finally launched. I suppose you are looking for a crypto multi-poker site but I think it is better to play in big fiat sites, such as Pokerstars, because in crypto sites there is risk of collusion and you are not going to get enough variety of games to play and there won’t be enough traffic.
I don't think they ever did, and if those projects did launch they didn't get too far before going down. I wouldn't suggest crypto poker at all because of collusion just like you said. Seems like poker isn't too popular with the crypto gambling crowd atm.
