How to Choose Secure and Safe PTC Sites Easily

If the PTC site gives more money for clicking ads, then they have to give fewer ads. If they don’t give fewer ads, then ultimately the site will turn out to a scam. Let me give an Example for understanding purpose, Suppose the site has 40 ads and they give 0.001$ per click, then this Site will ultimately turn out to a scam cause the site owner's wont get anything and they will turn to loss in businnes. If such site with 40 ads and gives 0.0001 approximately, then we can say that this site may be Legit. We cannot judge a PTC Site quickly.
