In my humble opinion, more people can win in the pyramid than in the lottery. The whole experience of the pyramids proves this. I can agree, (what else can I do?) That they will lose about 80%, but still it is less than in lotteries. Plus, in the rules it is clearly written that the game Ponzi is a pyramid. All is honest and there is no deceit.
That doesn't answer the question. The chance of winning this week's Powerball is roughly 1 in 292 million. I can make a decision to buy or not to buy the lottery ticket based on that. Ponzi participants have no such information and can't make an informed decision. Ponzi is not a lottery.
Well, if you are satisfied with this, then the chance to pick up the ponies in all players is the same. Since no one can forbid you to go out on any day after 100 hours of being in the game. Consequently, your chance of losing your deposit depends only on your own greed. And not from the deception of the administration of the game.
