For me, do it both! You can do crypto works in any place unless you have a computer and a connection to use. I'll pick first the job that is stable accept the overseas job that I can expand my knowledge and skills to be a better person. Then do bitcoin works if you have spare time. make it just a secondary source of income and your salary in your job may help you to improve your status in crypto like in buying mining machine that we all knew that it is expensive.
