Peak-End Rule

The Peak-End Rule is a psychological heuristic that suggests people judge an experience largely based on how they felt at its peak and at its end, rather than the average of every moment. In cryptocurrency trading, this often manifests when a trader recalls the massive high of a bull market peak or the sharp drop at the end of a cycle, while forgetting the long, tedious months of sideways price action.

This heuristic influences future risk tolerance and asset allocation decisions, often leading to irrational exuberance or panic selling. Understanding this rule is vital for institutional traders managing client expectations and for retail investors attempting to maintain emotional discipline.

It highlights why emotional memory is often disconnected from the mathematical reality of long-term performance.
