Get-Paid

Make money doing simple tasks, watching videos and completing surveys.

Money goes directly to your paypal account. Payout is everyday, minimum payout is $0,50.

I really like the tasks this site offers. It has the image flagging for google tasks that i really like to do because it's easy and quick once you get the hang of it. It also has a daily survey system that pays you 40 to 75 cents for a filled in survey, and you can repeat this every day. Third nice thing is that you can play simple games and bet some money on them and that get-paid has video ads almost everyday.
From all the PTC sites i tried, this is the one that i made the most money with.
