Honestly I don't know actually, I had some faucet and I know how popularity/visits/design/banner placement etc are important to monetize your ads, and their alexa rank is so high considering how much few time they are online http://www.alexa.com/siteinfo/bitfactory.co in 2/3 weeks from zero to 150,000 and this is really impressive...trust me... Maybe they can pay people just with their ads earning...it's possible if their site continues to grow so rapidly...maybe they can't pay all with ads earnings but this is a great income anyway..

Now I have a question, admin can you tell us how many unique visits have you daily?
