Earn Dollars by Clicking

Its been a month since i started to join ptc or paid to click as the way to earn extra money from the internet and i just found out that to earned a lot from this type of earning money online you must have an active referrals. Referrals are the one who signed up under you. I had also tried exchange referrals but it was turned out that some of my referrals are not anymore active although i am very much active on their ptc sites. How disappointing isn't it?
