Before, it is possible to get a whole bitcoin from faucets. You just need a ton of referrals and viola!!! But now that faucet users are in the decline or don't really spend a lot of time anymore as they use to, it is now impossible to get a whole bitcoin.
It will take you many year to get one bitcoin in faucets and i can be sure that you will stop because it so boring in that site, and i can see to earn 1 btc is to get higher paying job in service section where if you knew how to make site well you can earn bigger more knowing programming and website making is the highest paying job in online world but if your relying on free well it takes time to get it on faucet, sig campaigns and other more.
