That is really good of having 3 k crypto mail id . Just curious to understand how did you manage to get that many mail id ? Did you had some survey taken from all of them through which you got it?

It all depends how popular your sites becomes. If you get a million users and you are paying 200 Satoshi's per hour.... then you can do your own

calculations. { very over simplified example, but you get the idea } Freebitco.in has 4,394,065 registered users, but my guess is.. only 10% of

those might be "active" users... or even way less. Operating a faucet is a science and you need to balance income and expenses very accurately to

survive in that scene.  { Do not pay people once... and they leave }

It would not surprise me that the biggest faucets out there make at least 0,1BTC per day if not more. I think this is a very profitable business if done the right way.

faucet business very very competitive, the owner must creative in manage for interesting many visitor (guest and member).
Like freebitco.in, this site make creativity management with reward point program, so it can be interest to many visitor. Other creativity, with expanding program with multiply btc, survey point, or other more offer

This is not true, you just have to think outside the box. I am making a decent profit with my faucets without Adsense. I have 4 different streams of revenue on each and it does quite well. Not enough to live off of, but enough for some supplemental income 

If you want to include owners of bitcoin faucet rotator websites, I usually make anywhere between 150K and 250K satoshis per week (0.0015 to 0.0025 BTC). It has taken me a long time to get to this point, and those amounts are very small.

Depending on marketing efforts, I can make anywhere between 0.002 to 0.007 BTC additional per week from advertising (using MellowAds). The amount I earn from ads very rarely gets over 0.007 BTC per week, but I have already made 0.011 BTC in the last 7 days.

I earn enough to pay for hosting, domain and email renewal, and some advertising via MellowAds and A-Ads.

So to answer your question (if you accept answers from rotator site owners), I can get a total anywhere between 0.0035 and 0.0135 per week.

Faucets seldom earn the owners much.  The profit margins are extremely small because it's very competitive - faucet users mainly only care about which ones have the highest payouts and since you can't even use AdSense it's quite hard to earn enough money to pay the satoshi.  Sometimes faucets even scam that tiny amount of money off of their users.

If you're lucky you could get a few Bitcoin per year with a lot of maintenance.

1. i am not so sure about the capital but it shouldn't be anything bigger than 0.1BTC.
2. Adsense is always the best way of getting paid for banner ads but it does NOT allow faucets and it will close down your account if they find out. you need to stick to smaller places that also pay in bitcoin like a-ads.
3. not much. faucet job is both bad for users using it and the faucet owners since not that may people visit faucets and the ad payment is not that fancy either.
