Costly Signals

Signal

In the context of cryptocurrency, options trading, and financial derivatives, a costly signal represents information conveyed through actions that inherently incur a financial or resource expenditure, thereby demonstrating commitment and reducing the likelihood of spurious communication. These signals are valuable because they filter out actors who would otherwise make misleading claims without bearing a tangible cost. The presence of costly signals enhances market efficiency by providing a more reliable basis for decision-making, particularly in environments characterized by information asymmetry and potential manipulation.
