I think it is possible, only if you have programming skills, know how to write articles, you are an expert in certain topics, basically if you know useful things, for which, people will pay you.
That's basically how everything works. You get paid for something you're good at at the price that you deserve. If you're really good at something and you know how to make money out of it, then you can make a living out of it. Otherwise, you have to step up your skills and do not stop until you reach the level of those that are on top. These are the key steps in making a living out of Bitcoin. Once you're at the top, money will come easy to you. You're not even going to need to look for a customer, the customers themselves will come to you.
