The Ponzi scheme business model can be sold off as a high return scheme. However the real purpose of the scheme is never revealed to a customer.
Customers are pulled in by the high return promised on their initial investment. These returns are unrealistically higher that prevailing in the market.
Returns are sometimes offered daily, with the total worth of their investment increasing from 1-5% every day or every week. This is more than what banks provide or what can be gained from the stock market.
