should i become a youtuber to make money??(15 yeared old girl who needs money)?

Firstly, you will need at least around 500 thousand subscribers for Youtube to even consider paying you, you will also need a massive amount of views for the same reason. Youtube may seem like a quick and simple way to make money but it isn't. You will need a Mac and decent editing software that will cost around £1500. Then you will need decent a camera and equipment which will cost another £1000 if not more. Then you have to go through the lengthly job of editing each video so it will appeal to the viewer. So in short, do not think of Youtube as a quick and simple way to make money.

Why is this under Immigration? If you are not a citizen or legal permanent resident of the country you are in, then you CANNOT legally work or earn money! Also, beware any relevant laws in your jurisdiction regarding work by minor children. You neglect to mention country of your citizenship, and the country where you're residing.

Assuming you somehow stuck your Q in a wildly-wrong category, what makes you think you can earn money off YouTube? People watch YouTubes for free! So how large a following do you have for what that is so different & so desirable & so valuable that you think you might have some way of making money off YouTube? And do you even have the video & video editing equipment & softwares, expertise in making professional videos, & exclusive CONTENT to begin with?

Just because you heard "somebody" makes money off their YouTube videos does not mean just anyone is capable of replicating their formula for monetizing their work.
