## Sunk Cost Fallacy in Trading

The Sunk Cost Fallacy is the tendency to continue investing in a losing trade because of the resources already committed to it. In crypto trading, this manifests as holding a depreciating asset in the hope that it will return to the original entry price.

This prevents the trader from cutting losses and reallocating capital to more promising opportunities. The resources spent ⎊ time, money, and emotional energy ⎊ cannot be recovered, and they should not influence future decisions.

Overcoming this fallacy is essential for maintaining a disciplined approach to capital preservation and growth.
