Do not ever depend on bitcoin because we do not know if this thing is lifetime. You should bitcoin as your alternative and find a job that fit to the things that you really want. I do not depend on bitcoin because there is no assurance that you can earn money so I have my permanent job.
Actually, it depends to the people if they will depend their life on bitcoin or not. However, I depend my income in bitcoin because I'm full time worker in bitcoin which I do daily trade and I do not have permanent job.
