seven dollar click -is it a scam

Today I found  a PTC - Paid To Click sites that give you a very attractive income which is 7 dollar per click(180 seconds). you can withdraw after your account achieve a minimum 7000 dollar which if you calculated after 1000 click and if counted 5 click per day, after 200 days(almost a year). but the questions rise is does it pays??? what i can see that most of the PTC's sites only pays their participants merely 0.001 cent's per click and you get 10 ad's to click per day....but yes you can say that you can withdraw your money after a few cents. but bear in mind that a few cents and a few thousands dollar?? so what would you think of this site?? visits the sites at http://sevendollarclick.com/ and tell me what you think of it?? for me and this is my opinoin only...it is a scam....logically...nobody would pay you and I meant it especially advertisers would pay you 7 dollar just to view your sites......however I would want to know what you think about it? signing off for now....
