There are only 2 real ways to make what anyone would regard as "A living" off of bitcoin faucets. 1 is through referrals. Realize however, that you're basically getting other people to waste their time so you don't have to. Eventually they'll grow tired of it and move on to another faucet that pays slightly better. So spam your referral link everywhere you go in hopes that a few random people who haven't figured out that faucets are a waste of time. You can work a job you loathe for an hour and make more than what visiting faucets for a day can earn you.

The second way is to run your own faucet. Guaranteed page views, advertisers love that, but you have to be giving away enough bitcoin or have some gimmick that really makes people consider your faucet worth visiting over and over. Otherwise the ad revenue dries up, you have to front even more of your own money to fill the faucet, and you've stopped making a living. The worst part is, if you can't pay people who've earned any significant amount of satoshis from your faucet, you get listed as a scammer. Then you can't really try this again unless you're reaching a new audience that wasn't aware of your prior faucets.
