Profitable. Only you need to think carefully. With the right approach and good advertising, you can get a satisfactory financial profit.
If you run any site its always profitable via Google earnings and other sort of services by advertising it. Same like how epay.info doing it. This site simply good for newbies and you guys can make satoshi in regular time period and payment has been processed on every Wednesday.
That is another way to promote your site through advertising but it would incur additional cost just for hoping that it will increase your site's traffic. I would rather focus on the quality of the site than advertise my site right away. The faucet game is getting harder and harder because a lot of them fail early on because of wrong decisions.
