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.
I agree. This field is very risky to depend on because all of the coins are volatile. You have to get job and make it as an extra because not all the time the price is worth, sometimes it is down where you could think to leave it sometimes. Real job can provide you with fixed amount and your skills have to develop for you to grow and have much better future.
