Don't you get it? Its not a ponzi scheme... Its a scam. They pay you the first time and the next time they screw you over.
their level system is just a way to make sure you'll be busy for a few days
Well their "Level System" sounds like a Ponzi Scheme to me, which is a type of scam. That fake email thing is pretty messed up though! I bet this site will be gone within the next month or two after they collect enough BTC, so ya, it's basically one big BTC scam like we see everyday.
