Erm, the sites are labeled as a ponzi scheme, they aren't lying. All it is is another bitcoin gambling game, just like satoshi dice, you may win, or lose, but the person USUALY does not run away with the money
Did you just defeat your own argument before giving me the chance to do so ?
Anyway lets break it down, a gambling game has an average payout of around 95% or higher but individual payouts can range from x0 to x36 (using roulette as my example). A Ponzi's max payout is usually 80% (individual payouts being 1-7%) then they pack up and run, there is NEVER a payout greater than 100% just operators pretending to be players and their shills.
A Ponzi is a scam.
Again since Im dealing with idiots I'll give you an example.
Doing surgery without a license is illegal.
The reason that we dont allow people to operate with a disclaimer of "derp Im actually just a butcher" is because as a society we need to look after the weaker links in our chain.
In case your not grasping my point, you strike me as the type of person who would see his local butcher/ vet to get his appendix removed and then advise others to do the same.
