It's not actually earning a living with bitcoin because my earnings from bitcoin are not sufficient to meet my daily needs but it is really a big help on my budget. Bitcoin is really helpful to lots of people.
Yes its a big help because of btc i have extra money to spend for my personal needs, though i cant go full time in btc i still have time to earn btc and im contented with just that. i also have real job and business so i have to manage my time.
We can earning bitcoin for living, there are some ways to get it depend on your skills, like in this forum some people offering graphics design, editor, manager, etc. If you have more capital you can create your own site, and some people doing signature campaign for those who have the site. But if you just could have some btc for extra money, it's okay.
