It is good to innovate and try to keep it going, I think it is one of the best ponzis out there but let's face it : breaking a 2BTC deposits in 4 0.5 doesn't change much and I am going to tell you why : 4*0.5=2BTC

I think the website needs a little bit more than that, maybe a promotion 50% for the next deposits and the older deposits only get 10%, I could settle for +10%!

Maybe some adds on bitcointalk : https://bitcointalk.org/index.php?topic=482060.msg5301372#msg5301372 If the owner takes a commission of 2% he only needs 65BTC of new deposits to pay the adds, 1 200 000 impressions on bitcointalk willl definitely bring that many deposits because people will be redepositing their profit
