The true 5% of traders that are very successful and profitable do not even have a YouTube channel (only a very few exceptions). They are strictly for trading only, day in and say out.
Having a youtube channel doesn't make you a successful trader. The purpose of making a youtube channel just to educate people about certain strategies and events in cryptocurrency scene or just solely for some good chunk of money through youtube views and ads. I do not see an appeal to follow all the advices from youtube videos, because it could be outdated.
Trading is not profitable for some people and it's not for everyone.
