It's called fake testament, and sometimes they even come with proof but it's still all fake, the truth is those who make money one way or the other don't share to the public how they do it, greedy people will always feel like ' let me give a try, who knows? ' and their eye will open once they get scammed
in this cryptocurrency market there is something like this. example: someone buys an altcoin for the price of $10 and wants that altcoin to increase the price a lot, that person starts with creating threads here to speak well of altcoin, then stays in the telegram channels to speak well of altcoin to make many people buy altcoin and the price of altcoin increases a lot and he gets a profit of 2X or 3X. Most of the time altcoin is a meaningless project, but as the person bought for $10 and wants to make a profit that person will promote that project everywhere. this is not different from the story that OP spoke. in the cryptocurrency market there are modern scams that people have not yet realized that are not different from the obvious scammers
I always wondered - if the "alleged scammer"(let's call him that) is such a successful trader/analyst, etc. why would he tell the others how to make a million? After all, they will create competition for it. Unless this "alleged conman" is going to make money off his students)))
this is the same question that many people ask people who create youtube channels to teach trade courses and sell their trade courses, the same applies to sports trades that create youtube channels and sell courses for trade tips
