which is the best site to invest money in ptc sites..?

I have invested in 07bux.net and it is going great. I've rented 250 refferals for 55 $ and now, after about 2 weeks, I have 141 $ and 2 and half weeks left.:).I think this is much better investment of mine then neobux. At least is much faster. Admin is reliable and now trying to put ''instant'' and they have paid off more than 150 000$.

Cash Crate is the best one. Would you sign up under me? There is no investment.....
