If you are talking about a single user: out top earner gets +10,000 satoshis every day: 3k from shares, 1k from CR, +6k from referrals.
If you are talking about the faucet itself: it cost us some money, around 50-70K satoshis everyday just in payments, plus hosting, dedicated time, etc. LEts say 0.02 BTC monthly (14$)+ hosting (5$) + SSL (soon, 1$) = 20$ monthly. Why we are happy to spent this money? Because our site is not a short-term website, it will be a BTC all around dedicated website, and 20$ monthly to win popularuty and confidence from users is not only cheap, is almost free.
By throwing 20 bucks a month are you making any gains is what i wanted to know. Nice plan though.
