Whatever you say. Ponzi = scam!

Explain me something. New deposits cover previous users. the larger the network, the more deposits are needed, you also promising +50% profit.
What happened when all people want to leave your system and try to cash out his profit? or if the influx of new suckers is reduced and you can't cover all promised profit? You will close this website and move on? Or you plan to pay all claims as not to deceive people?
