Just a general reply, once btc fixes its scaling issues there will be billions of ways to earn btc only limited by ones own imagination.
Right now faucets are worthless, and most other free things are worthless unless you are well known, signature campaigns are ok, but generally you have to invest because there is no free lunch.
besides earning with faucet and signature campaigns there are a lot of other ways of earnings also available like if you will have any skills like the skill of designing then you will earn a good income especially if you are able to design a thread or signatures then you will have a load of work from this forum.
