I don't know if there is an ICO that focus only poker tokens. They have a lot of past Casino project ICO that offers Poker game if this might be in your consideration then I will give the complete list here. Just an additional input and promotion too. I'm working with a team that plans to launch an ICO that focus only on poker and the devs team have a good portfolio. They are working with PokerStars and Zynga games in the past. Actually, they started developing last year but due to some unforeseen problem on the license issue. The timeframe got extended but I hope that it will launch within this year.
