I think the concept of the game is a nice idea since users don't need to gamble to make money, but the part of paying $10 before one can make withdrawals is what scares me, I think the payment of $10 will discourage a lot of persons who wants to play the game and don't know if it's really a scam or actually a real platform.
You guys might have to build a lot of testimonies to bring trust by users. I think the best way is to come up with another method users can use to make withdrawal without having to pay $10.
