Raw Optimal ( f ) often tells a trader to risk 20%, 30%, or even 50% of their capital on a single trade. While mathematically optimal for logarithmic utility , this leads to massive drawdowns (sometimes 70% or more) before hitting the exponential growth curve.

Instead, it is a dense, equation-laden, mind-bending journey into the mathematics of survival. Raw Optimal ( f ) often tells a

He famously proved this using a simple coin-toss game. Imagine a 60% win-rate system where you win $2 for every $1 you risk. Statistically, it’s a gold mine. Yet, if you bet a fixed 50% of your capital every trade, you will eventually go broke despite the positive edge. The math guarantees it. it is a dense
