I don't think this is a gamlbing, it is more like an investment thing to me also i don't understand how things are done i think i have seen like this before on some investment thing and i think its more like a ponzi scheme to me i really don't think investing here would be a great idea but if you really wanted to invest here then just be careful and invest only what you can afford to lose.
Even if it is investment scheme or a gambling game, it is very difficult to understand. I have tried to understand it and read it twice but fail to understand it perfectly. This would be first Ponzi scheme where people will paly and they will not know what happen to their funds as they will keep on guessing the game on how to play it
