I am commenting without doing any research but it sounds like Ponzi to me. One of my nearest family member played and lost a lot of money in Dhukuti. But I never had courage to ask why and how. Since I live in US I perceive that my inquiring would be felt as interrogative and I am not liked (from what I hear). Hence I could not ask. We do not talk about it. I did not do a detailed analysis of how the game is played but the brief deskription by another poster sounded like this is a plain vanilla Ponzi. Having failed to stop even my closest ones (and most likely my parents may have lost money without telling me), I have come to the conclusion that I am an unintelligent person who could not convince his own family from being financially ruined. Anything that does not add Economic Value can range in scale starting from a flat out Ponzi (Bernie Madoff) to a financial bubble (refer Credit Default Swaps, CDOs and many Hedge Funds).
