You can earn money by doing job obviously.
It's depends from what kind of skill you have, you can either promote your skills on service section or just do some freelance work.
There was a guy who asked same question, check this thread
https://bitcointalk.org/index.php?topic=5284125.msg55443317#msg55443317and when i gave him few recommendations, he earned $100 by doing some tasks
Will anyone please help me understand properly how to earn bitcoin other than the option of buying them from debit/credit card , i'd really like to know some freelance ways to get bitcoin / ether/ etc . would anybody be kind enough to share some links with some advice on how they actually work ...
Sure, when i searching on google about what freelance will give you bitcoin for the job, i've found this https://www.webemployed.com/freelance-websites-pay-bitcoin/
I told you first, i never try or joined in any of those 7 sites, so you can just try without deposit anything on those sites (i've only seen we just need to offer our skills on there, so it seems safe)
