Those all channels you are talking about are zero base meaning the video host don't have any knowledge about bitcoin and crypto market at all and have clickbait titles to attract the audience and when you open up the video first few minutes are about channel introduction and then they only promote some shitcoins under paid influence and all that crap content.

But the forum already has a youtube channel BitcointalkShow if you could check the above post and lot of discussions have been made about the same but there is no update from few months.

The other youtubers are only paid shillers who are manipulating the viewers under cash grab scheme and then people loose money after following their advice.But the forum channel was producing quality content with variation and liked by many so still hope for next videos.
