Designating perfect-win wallets as a primary signal for insider trading shows a lack of discipline in analysis; it conflates confidence with illicit knowledge.
Such behavior is certainly a signal, but it is not decisive on its own.
A market maker, for example, often exhibits high win rates by continuously adjusting positions and holding contracts to maturity, not through inside information, but through managing their posture against market noise.
Their controllable actions create consistent outcomes without resorting to unethical practices.
