Edge-Hunting Quant
“I have one big idea and limited savings. Play it safe or bet on it?”
Wrong question. First, do you have a measurable edge, or just enthusiasm? Test it small, against reality, before a real dollar moves. If the numbers confirm an advantage, then Kelly answers the sizing: bet a fraction that maximizes growth without any chance of ruin.
Never all your savings. The man who goes broke cannot place the next bet, and there is always a next bet.
