This IS a pyramid... i.e. a completely transparent pyramid.... the second oldest one in the Bitcoin world.... but it is also an advertising platform... you can get paid for the ads.... your odds of getting paid from ads or new users depends on your level of participation... in that sense it is a controlled gamble....
A Gamble.... so stop throwing out words like 'ponzi'. A ponzi is NOT TRANSPARENT.... you can literally follow the money on this site all the way back to the beginning.... you know it all... where it comes in, how it is distributed, where it goes out.... it is a pyramid... not a ponzi....
And unlike most pyramids it is also an advertising engine.....
