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.
This has also received attention from me, if a YouTuber really makes big profits from trading then why do they create a YouTube account about the basics of trading or about trading because it doesn't take long to become very skilled as a trader! returning to the discussion about what actually produces results for youtubers, it is advertising, so the goal of a youtuber trader is only to get money from other sources.
