I don't understand how there can be such dumb people who believe that some guy on social media will make them money, and worse, give him money that they manage to earn with effort and hard work...

This is directed at you, yes you who are looking for easy paths and end up being scammed. If you don't plan to educate yourself on how to trade, you better keep your money and just save it, no one will make you rich at the expense of their work and time, while you lie around waiting for easy money... Don't be stupid.
