I believe these guys tell the story about their own experience and perspective, and it cannot always be applied to other circumstances. It's like what Steve Jobs said about connecting the dots: "You can't connect the dots looking forward, you can only connect them looking backward." But sure, there are always common financial theories in these books with some storytelling to make them more appealing. If you have already read college books about finance, there's little value other than good stories, and probably some aha moment where you understand this theory can be applied in that situation.

That said, always go with the basic knowledge about risk, portfolio, etc. then you can pick any complementary books you want. I'd rather follow some crypto news/influencers to get some updated things since you said yourself that it's "fast-changing," meaning if it's already in the book format, you'll hardly get any fresh updates.
