How are you going to warrant among players that this site will not disappear anytime? I mean, there are so many short lived casinos, where you don't know if it will still be there the next time you visit. And any reason why you chose nano for this game?
Actually it does not matter if the site disappears or not,,, this game appears to be PVP so you just play, and you do not leave any of your deposits there. Simply play against each other, win or lose, you take everything out.
NANO is the interesting choice though.
