To my knowledge youtube can only use adsense ads, may be different if you use self host to create a youtube channel, may be able to use ads other than adsense, I've seen there is a youtube channel using ads other than adsense
So far I know about YouTube there is no way to earn Bitcoin by this platform, YouTube doesn't offer bitcoin directly, so it's not possible to get Bitcoin through the YouTube link, but if anyone can make a vedio about Bitcoin then that vedio link will bring money, not bitcoin...
