If someone found a way to get rich, he'd never expose it and would just keep getting rich

I'm talking about crypto YouTubers promising to teach you the techniques to become a crypto millionaire or about people selling entire courses teaching you all the ways to find the best Shitcoins.
To me it sounds like a paradox.
If I'd found a way to make easy money I'd never share it, and I'd definitely wouldn't need the money from YouTube or from selling courses or books.
Just because someone on the internet says he's now filthy rich, doesn't mean it's true.
If there's a way to become rich easily with crypto you'd have to find it yourself.
