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.
You'll see them on Instagram or WhatsApp posting many signals, doing adverts for their VIP exclusive signal groups. Their appearance of wealth has nothing to do with their profits from trading and trading performance but from their courses sold and YouTube ads.
If you have time to analyze, understand or make an investment with knowledge why not take a risk of it than taking courses which the same you can get in the internet, well possible we have different learning phases but think twice if its realty worth it?, i don't trust these signals after i learned about trading. As possible stay away with these things could be lead to scams.
