I dont understand the hate either. In casino or ponzi other players have to pay for the winner. Casino or site owner is not going to do this. Its not faucet. Then whats the difference between those two? Its just different play style. In casino you are loosing small to win big and in ponzi you are winning small hoping to not loose big. But the chances are the same.
 Also people dont even know how many ponzi schemes are in real world. Look at auctions. People are buying expensive old paintings or old cars and selling it later with profit. Paying really huge money for this. Why not jump them and say they are stupid? Or markets, or even housing. If value drops someone will be left with that bag.
