I think many of the people works on paid to click sites as standard member but we upgrad our account for one month then what is the profit. I work on clixncash which is a reliable ptc site. I have paid more then two times by clixncash site. before 2- 3 days i have upgrade my account for one month by paying 3$. Which is silver upgrade. After upgrading account i observe site is taking more time for opening and viewing ads as compare to standard member. What is reason behind this. Pls tell your views.
