You can earn it for free with mining or faucets but it will give you a small amount of satoshi's or you can work for it like what we have here in forums Ex:campaigns,bounties and different stuffs.

Those are the best and common way to get bitcoin without investment but you can also get bitcoin by doing freelance like for example you are a good programmer and you can program different things with different programming languages and that is your advantage because you can attract a lot of customer and you can ask them to pay you in bitcoin and that will become the way to earn bitcoin without using any money.

Hey there having bitcoin without investment us nearly impossible. Investment in a form of money that would be impossible but you can invest time and effort here in the forum. You can learn here the basics first and afterwards you can read more on topics like trading, and other opportunities.

- Yeah, there are many ways to earn bitcoin without investing, as long as we have the skills and experience in a certain area, we can use that skill and experience to earn bitcoin, a programmer, an interpreter, a logo designer or any other service someone needs. Want to earn more bitcoin without investment, we should choose the work less people do and less competition, signature campaigns and social campaigns are so popular, if we just newbie, we are very difficult to compete with others

Without investment, well there is no without inivesmen. There is always invesment of time, effort and knowledge. But what i already tried are signature campaigns and faucet but this consumes much time specially the faucet but the signature campaign is worth the wait because as you rank the salary increases too.

if not invest or trade I think it's hard to earn money.

but to be honest you can get through ico project. and can follow the campaign. but do you understand? there must be understanding,
I just gave feedback.
you should first increase your rank.
while you learn and understand in this forum. do not forget to read also the rules about this forum.

Yes signature campaign is the best way to earn bitcoins in the most safe way and stable way as it will surely give you regular income on weekly basis depending on the rank and the part of campaign you are and apart from that I don't find any other easy way to earn bitcoins.

I think facet is just the wastage of time and nothing else. I think earning bitcoin through signature campaign is relatively better that earning that faucet. I am also earning bitcoin through signature campaign but still my main income that I get from bitcoin is through trading bitcoin and some time other altcoins.

Through faucets and campaigns although some people considered faucets as a waste of time, there are still some that said it helps them earn Bitcoin. But bounty campaigns will surely take a hit. There are different campaigns within a bounty campaign there's signature, translation, and social media campaign. You'll just join a campaign of your choice and joining is free. Follow the rules and finish the campaign because at the end of the campaign, tokens or rewards will be distributed that can be converted into Bitcoin.
