Buying monetization channels has its own risk. As you know, YouTube was tighter in allowing the new channel to monetize on their platform. They will still be strict even after the channel has been approved for monetization. The channel will be quickly demonetized if they detect any violation from the videos, even if it’s the first time. To be honest, the Monetized Channel is more suitable for old YouTubers that already know YouTube’s monetization policy as they can avoid undue risks.
However, it doesn’t mean there won’t be a chance for new YouTubers. Have confidence if you are serious and want to make money with YouTube. You can learn the policy carefully and adhere to it as other YouTubers do. Everything will be fine.
