Sunk Cost
Sunk Cost: Irretrievable Past Investments
Sunk cost refers to money already spent that cannot be recovered, which shouldn't influence future investment decisions. It's like refusing to leave a terrible movie halfway through just because you already paid for the ticket.
Sunk cost describes past investments or expenditures that cannot be recovered and should not factor into future decision-making processes. In cryptocurrency investing, recognizing sunk costs helps prevent emotional decision-making based on past losses rather than future potential.
How Sunk Cost Psychology Works
Loss aversion makes investors reluctant to realize losses by selling declining positions because they hope to eventually "break even" on original investments.
Escalation of commitment leads to throwing good money after bad by increasing investment in failing projects to justify previous spending decisions.
Rational evaluation requires assessing future prospects completely independent of past investment amounts, purchase prices, or emotional attachment to previous decisions.

Real-World Examples
- Holding worthless altcoins indefinitely hoping they'll recover to original purchase prices rather than cutting losses and reallocating capital
- Continuing unprofitable mining operations because of money already spent on equipment rather than stopping based on current economics
- Supporting failed crypto projects with additional investment simply because of previous financial commitment rather than objective current viability assessment

Emotional discipline by understanding that past investments create no obligation to continue supporting failing positions or projects.
