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.
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.

You ask yourself why don't they stop all these bs and just go back to real trading and you will immediately answer yourself that trading is hard work. It is easier to make reliable income streams from acting like a trader than actually in active trading where the market is volatile. It is easier to build a personal brand and audience in the short term than it is for achieving trading profits. I do not like these people because, to me they are scammers. I have never seen anyone who follow them that eventually became a successful trader.
