P.T.C mean Paid To Click as name clear you must click to earn money.
How PTC sites works?
ptc sites interface between us and advertiser, how?
Good question, advertiser pay to this sites to showing they banners, and PTC sites pay us to click them ads because you referred to advertiser site and seo and google ranking of site go higher (if you want to i tell more about that tell me to post it for you).
What have for ptc sites?
Very nice question, guys for example if you received 200 satoshi for one click they get 250 satoshi from advertiser
PTC site get 50 satoshi but we must also consider the cost of server and many thing else.
Every one is happy us , advertiser and ptc sites for all is good.
