However, I can say that almost every user here knows about the YouTube channel. Because those that have been a while in the Bitcoin investment, most of them acquire their knowledge from the YouTube platform, but not where they start their Bitcoin journey? It is after they have gained a little knowledge that they want to do their own research by watching YouTube videos.
You can not step in shoes of the others so you never can know how the others learned about Bitcoin. Not all people like Youtube and engage with Youtube videos so they don't actually learn Bitcoin from Youtube.
Knowing that there are educational websites, Github, books and more resources for learning and Youtube is one of channels only. However Youtube videos are not best resources for learning as you can learn more easily and effectively with books or websites with texts. You can easily read content again and again, anytime for learning and it's not like Youtube.
Assume you are learning from a 30-minute or 1-hour video, you will struggle to find a time on which a content was talked, taught. It's very challening to find your wanted information through a long Youtube video.
