First and foremost, I want to congratulate you for finding a way to pursue your interest in Bitcoin. I think the best way to start with Bitcoin is to get to know more about it. You need to know what is Bitcoin, what does it offer, why is it so valuable to so many people, why it becomes so popular even to those who are not actually supporting it, and so many others. These are the more important matters, definitely more important even than earning Bitcoin. But of course it will follow sooner or later. I think it would also help a lot if you explore the beginner's section here in this forum.
