I don't agree to faucet because it only gives small amount of satoshi and it always depend on your effort but i think that doing faucet is a boring thing to do so it will not give you steady income. But those two (Trading and signature campaign) are truly gives steady income because in trading you can earn between average to high profit every week that depends on your performance and also in signature campaign, it can give you steady and fixed income since most of the signature campaigns stated a required amount of posts every week.
