It is possible, but only if you have the necessary skills. But I don't recommend you completely abandon official work. No one knows what will happen with bitcoin in the future. You risk to remain without money and pensions. You will agree with me it is very risky.
I agree with you much better have a regular job and then work here in bitcoin I think you don't need much time to spent here, 3-4 hours I think just enough after your work. I think at this time you make double your income not only by your official job and also bitcoin too.
you can witness that after you learn how to maximize your earnings inside bitcoin industry, a lots of ways that will lessen your stress unlike with your day job
