Trying is not enough. You need to implement it asap and the value needs to be something like 0.003BTC or lower. Anything higher will basically deter investors from investing in your game.

The competition is fierce these days and there are plenty of alternative options like the PPPoker app on mobiles which offer better deals, bonuses, lower withdrawal options etc which is why your game could disappear in a flash unless you lower the limits and provide more bonuses.
