I have seen the birth of thousands of PTC sites (Paid to click) in the web world and also witnessed their sudden collapse.I have also earned little money from them but I never suggest any one to be deeply involved in any PTC and invest money.One site,I mean to say one PTC is an exception from above.It is neobux.com,the world's best.The site has more than 20 millions membership base and had already paid $12,114,733.70 to the members.The site is still paying instantly.I have been paid 5 times from it. But I don't know,how the site still survives although thousands of PTC sites has fallen to ground.
