Most of the terms and contract that you had to agree doesn't really matter at all. As long as you agree with the payment and you can finish the project, most of the employers are just looking for that possibility that you have the ability to work for the given job description. And this is why there are a lot of freelancers that earn bitcoin.

This is my free earning Bitcoins
Sigature Camp  - earn btc by joining In the discussion
freelance -Get paid on your skills
Faucets Earn a small amount of btc by claiming daily

Joining signature campaign is the one way to generate a bitcoin. Based on my experience, I much prepare the generating of bitcoin than buying or investing because I have no money for supporting my online job. And the money that I get from signature campaign was been used for trading to get more profit. In bitcoin, the more way you know about bitcoin the more income you can get.

Bitcoin can be made by signature campaign , freelance and some small amount by faucets also but they are not free we do have to invest a lot of time towards
in my opinion faucets are  not actually a way to even earn bitcoins
we use have to open some apps and collect them daily by seeing advertisment
signature campaign is actually a way to earn if you are expressive and they pay accordingly   
one can go for gambling also if they want to earn more bitcoins but this is more risky and requires a good luck

Couple of ways where you can earn legit bitcoin ->

~ Joining the signature campaign depending upon your rank and posts you will get paid.
~ Doing Freelancing projects depending upon your skills and requirement and get paid in btc
~ If you get some btc from above process and ready to take little risk you gamble and get more btc.
~ You can develop and learn the skills for trading btc and do trading and get more btc or profits form it.

There are many ways to win Betquin without investment and the best way signature compaign This is my favorite way

I'm a newbie and so interested in learning bitcoin.

Selling skills is a good idea, but not very popular. Now a lot of good programmers. Find a job for which pay bitcoin is difficult to find. It is easiest to join the signature campaign.
Without investments it is difficult to earn a crypto currency. Very difficult

Sad that I do not have a skill to post on the marketplace.  I bet that would be a great earnings considering that it is your skill that you are selling.  And mostly everyone here earns through signature campaign as this is the most easiest or should I say convenient way to earn.  My earnings here is such a big help for my family as I was able to earn an extra income for other finances.

There are actually a lot of ways to earn bitcoins online without buying.

You can instantly earn bitcoins in various faucets. These are websites that give you a small amount of bitcoins every minute or every hour usually for you try out their gambling site without risking your own money. Such sites require a minimum withdrawal fee that ranges from 30 to 80 thousand satoshis. And since they only give a little, it will probably take a long time before you can withdraw. Next, as I have mentioned recently, are the gambling sites. Here you can try your luck and play different games like casino, lottery, dice games and others for the chance to win bitcoins. But there is also the risk of losing everything instead of earning, so my advice is not to invest here but to use the faucets instead and try to profit from it. Of course there are the signature campaigns. Here in this forum, you can join a campaign depending on your rank, and get paid weekly by posting on bitcoin related topics while wearing an ad in your signature. This is probably the easiest way to earn and this is the method that I am using. These three are just some of the ways to earn bitcoins. You can always search the internet or other parts of this forum for more various ways of earning bitcoins. Good luck!
