Just like ALL forms of gambling both traditional, stock market, currency trading and Ponzi the profit you seek is gained from other losses - the bookmakers and casinos don't give you their money they give you the money that others have lost.
Whether you win at the roulette table does not depend on whether you can convince someone else to place their chips down after you.
You are either too stupid to know the obvious difference between a game of calculable odds and that involving socially engineering a 'greater fool' to send in money to the ponzi after you have sent yours, or you are pretending to be too stupid to understand.
I am getting paid so, i am here. that's it. Every one knows the risk factor and no one force them. they will invest with their own goodwill.
