In my opinion, why not make bitcoin a side job, yes, you can do your main job and invest or trade as a side job, and many of them also make people millionaires.
This quote is the most sounding option for anyone that is still confused including OP.

Making a lot of income streams is the best course of action, if you have the resolve and determination to do a lot of work.
