Just have a daily job and have also some Bitcoin if you have a daily job than you will have always money for yourself and that is good.
There is really a high chance that you will get poor in bitcoin if you dont know how to invest the money that you get and there is a limited jobs to be offered in bitcoin and that is not enough for a monthly expenses.
I also think this is very hard to achieve plus its the question if you will make the same amount that you will make with your normal full time job.
The point is that the bitcoin is also risky if it will collapse you will not have a job anymore and also lose a lot of money.
Quitting the job for bitcoin will never work, the only reason is the income is not stable and you don't know how much you will earn on regular basis.
the only solution to go against the instability is to aim at earning more with bitcoin
so you can save your ass in case the price tank too much, let's say you need to earn 2x at the very least what you're earning in your real life
