The best way to make money with bitcoin in 2017 without investment is signature campaigns. Even with tons of hates by other users, we can't deny the fact that signature campaigns pay actually pretty well. If you're doing signature campaign, then you are already better than most bitcoin users because some are just doing rev share, MLM, networking, faucets, solving captchas, etc. Not only these money making method are a waste of time, but you are also deceiving other people because you got deceived by another person.

In case that you have some bitcoins in you and you are willing to risk them, then I suggest that you try trading. Trading requires time and practice but so does everything else. I think that trading is a skill. True, luck is needed but if you know the coin, you can project that it will pump in the future and so you're going to invest in it. Just think about the early traders of bitcoin. They invested and held bitcoin for a long time because they knew that it's a solid technology.
