Sure, dopamine’s the brain’s “wanting” system, so it makes sense it fuels risk‑seeking, but turning that into a reliable portfolio model is like trying to predict the weather with a single neuron. You’ll need to disentangle dopamine from all those confounding variables—stress, hormones, even the time of day—and then figure out how to measure it in real time without a lab. It’s a fascinating puzzle, but be prepared for a lot of noise and a few “Aha” moments that turn into “Why did I even start this?” questions.
