OP, the girl looks pretty, but exploiting female body so much in the industry is not a good thing to do. Firstly, you are contributing to the general tolerance to violence and objectivation of the body (women are people, not some attractive things). Secondly, I bet a lot of women and liberally-oriented men will be lost from your potential audience this way. Thirdly, as betwrong mentioned, cheating might not cheer the customers up.

I also have the following question: how exactly are you going to accept all of the cryptos? I mean, what if someone just has a shitload of worthless tokens that never even entered exchanges and will try to use them for gambling? I am pretty sure other players will not be interested in playing poker with this person and if it's possible to exchange any coin into btc/eth on your website, people will probably exploit it and you'll lose a lot. In case you meant just the top cryptos but not literally any cryptos, you should change the name of the thread.
Good luck with the project!
