Many are teachers only few are traders. They make their money from selling trading courses, teaching trading classes, creating trading contents for YouTube and other social media. They have their own trading podcasts and collaborate with people like them to talk about trading yet, they have never been successful at trading.
Another factor is the use of the promotions its easy now to make a content into different platforms and share those stories in a form of text, post or videos to gain more popularity and not all the people are knowledgeable with the crypto or the trading itself so if those content creators earning a lot of money why not me those are the questions they as always problem and reason why they want to join in trading because they see an instant money.
I agree with the part that we all have a different way of learning and even we have different amount of time required to learn something. Let me show an example from myself without hurting anyone else, lets say I am some stupid person, and it takes me 9 months and a lot of different ways, like videos from many people, many written things, and a lot of podcasts etc etc, and I barely learn how to trade, whereas what if there is a person out there who watches a few videos from single person and becomes a great trader that way?
I think that's the most important part and I believe that will benefit everyone. This isn't always that radical and big difference, person to person difference could be tiny, but in the end we all have different ways to approach this situation in the end.
