The total wagered that won there on your platform is very big, I just don't know if what you say is true, it's like it's the first time I've seen that the top1 wagered around 11M$ almost and then the next one was over 6M$, that's doubtful.
And if that's true, why don't you add other games so that gamblers have more choices to play on your platform, improve your server as well. Although, the concept of your affiliate marketing system seems to be okay, as if it is mixed with a unilevel system up to the 10th level.
