A lot of the other comments say he’s not worth reading, but I’ll take the other side.
It’s been a while since I read the book and watched his interviews but IIRC he promotes the idea of “the fourth turning” and long term economic cycles being predictable. He uses examples from history to back his theory. He talks about debt burden and resets.
For someone who already went down the Bitcoin rabbit hole you might not get much out of it but maybe you’ll pick something up.
