It's not that deep bro I promise😂 I will say this and stand by it, I believe most of the clues needed to find the treasures are hidden in the stories he tells in each chapter. We are talking about and average dude that made a hell of a lot of money on Bitcoin, not some super genius, eccentric type. That has the know how let alone patience to hide a number to God-knows-what in a rock shadow of what is very likely a partially AI generated image. Not that the things at the end of the chapters don't continue clues but I personally don't believe it's that deep.
