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.
There is always reasons to this and it mainly revolves around,
Trying to get that capital, either from used having to subscribe to your signal channel or your YouTube channel so you make money from the traffics it generate with YouTube or you just get them to invest with you to trade on their behalf. It’s how it goes for most of them, only a handful of these guys that come on YouTube, claiming to be all professional and profitable are really profitable. The rest just use it for another means to get some money to trade with.
In all that, it doesn’t mean they don’t have ideas, it’s what you get at least, to learn their strategy and how they trade, apply it to see if it works and then, you can go with it.
