LOL this is NOT gambling nor an investment opportunity!
Payments will come from money of other people, without any type of bets behind. No people joining = No one win.
The last player play, it's a sure loss.
This site advertised it's just another ponzi/pyramid scheme or a scam ( he can close the whole website in a matter of seconds!)
Pyramid schemes are illegal in some countries, and generally speaking are just another way to lose money with "fake investments".
