Well you can actually go with bitcoin Full time if you are profiting more than what you are getting with working on your job, cause bitcoin really has a reputation in changing any persons lives by doing the methods in earning it Investing with it and trading that I think are really profitable
But In my opinion I prefer both you can surely get a job and earn bitcoin at the same time it only requires your time managing skills and your decision making to the test to make it really work out.
I am not taking my regular job for granted and actually enjoying in earning with both, and you both are right because stable job is a must than taking a gamble everyday with the not so sure to profit gambling game I am just telling them if you are getting a much more income in bitcoin than with your stable job it is better to choose one that is more profitable for you because not all person can do it at the same time like what I am doing now I can accumulate a little bitcoin and having a stable job at the same time.
