I notice you have a KZbin channel . I really appreciate your video quality is amazing. But not much views ,not much subscribers. Because many errors in your channel. Like tag sections, description, title , keywords are many errors in your channel . As a result your video SEO score is very low. So I recommend you need to proper SEO and PROMOTION. And if you want you can boosting. Then increase lot's of views and subscribers in your channel. As result you get monetize option.
