As a example trading could be a good thing to make a steady income, I think that is one of the best because the others are way more risky too.
I would hold it on this one to be honest.
I think the trade will not provide a steady income because you will not know when the price will go up, so you will not know when you will be earning
Depends actually in a certain person as not all of us will be successful in trading as we have different skills and capability, some might earn steady income in trading because they are good at it but I doubt if the number is big, most of us are just getting income by doing a job.
