Pros
The best part of working as an online content creator is that you are allowed to try things out. You get to learn and grow in an environment where there is no impact or expectations for you. It really is all about the individual running the channel and their desires and ambitions for it.
Cons
The hardest part of that job is that no matter how much you try, there will always be factors far beyond your control. The algorithm might not support your content leading to a loss of revenue, your viewers may not find your new video engaging making your work not worthwhile, and you must always be outputting content to attempt to keep your earnings up. Payments are the opposite of steady and can be very low at times, even when the effort and output is still there.
