Faucet is my the only one resource to get btc for free, but others source was my credit card
Its not free, you are using your time, your resources (bandwidth, PC or other device, electricity)
You earn more Bitcoins than siting 8 hours doing faucets. From my understanding the one who earns a lot with faucets are the one who owns faucets through advertising and those with a lot of referrals.
