Faucet can be profitable. You need nice layout, you need good hosting, you need some bitcoins to invest and you need some marketing.
You can profit by ads. I saw many of faucets getting nice money monthly paid from ads.
But also do not expect to gain a million. As it's named "faucet", you're giving a little, so you should expect a little profit. If more, better for you.
As any project it needs a time. You cannot make it famous in a week.
Invest and wait, but don't just wait, work on spreading a word about it to gain some visitors as you depend on them.
xD hehe Excellent idea but that whole fad will run its course in a few days or weeks.
