I have seen this type of ptc site for some time now, in the Google interface and in some traffic exchange sites too. I never believed its legit, secondly the reward for each ads is very low. Imagine where you are viewing ads that exceeds more than 10 secs for just 3 satoshis, that's weak. I will go again and check how much I can make with them via their website too. If I can really make up to 500 satoshis from it a day, if I can't make up to that amount, I don't see any need to stick around with their site.
