if I have stable bitcoin income, let says 0.5 per day, I quit my day job and give full time on bitcoin, but as of now saving bitcoin is my first priority then learning for some bitcoin investment to get my goal in the future.
I think you should consider you health because you can do that if you work whole day without sleeping but if you have skills that you can used in online i think you can do that. But I think its good if bitcoin threats as side line.
