why don't we look at the scheme in your sig? 

Hmmm, one guy wins, 9 lose.

So you get paid, the winner gets paid, and 9 others lose money.  90% of the players lose in this scenario, and yet you think it's a good thing, because the guy who started it gets the rake.  So not everyone has a risk-free source of income here.

Ponzi schemes ARE fraudulent, hence why they are illegal.  What is so difficult about this concept?  No, no, you see MY ponzi scheme is different, I promise.

No one with a functioning brain stem would willingly buy into a ponzi scheme or a pyramid scheme.  But then again, this is bitcoin.
