Earning money with PTCs is hard. So why don´t you automate it? Autoclickers preform quite well and currently there are 3 "big" Clickers

• Multiclicker from http://autoclickers.org
• Viv from http://viv.cryticalerr0r.net
• Anothercoder´s Clicker from http://anothercoder.wordpress.com (sadly, no plugin support so far... maybe in future)

Those clickers use plugins to work with different PTC sites. You can find them here. Please also take the time to read our "Getting started" page to avoid confusion.

Have fun
