You need to have at least 10k views to monetize videos on YouTube now
Among recent events, YouTube has decided you need to have at least 10.000 views to monetize a YouTube video.
Keep in mind these views apply to the entire channel, not to a single video. So if you have 10k+ views cumulated on your channel you are in the clear, but if you don't you need to up your game and up that views by publishing better content.
I know what most of you are thinking right now? "I will just by a ton of views from freelancers and everything will be fine"
Well, you may not want to do that if you want to make a living someday off YouTube. If YouTube catches you buying views just to get into the Partnership Program, well just say bye bye to the program because you won't get in and you will also get banned most likely.
