Key Takeaways
- Game Theory elucidates strategic decision-making in markets, including Bitcoin's role as a decentralized asset.
- The Prisoner’s Dilemma highlights tensions between self-interest and cooperation, mirroring Bitcoin’s trust dynamics.
- Pure Coordination ensures mutual benefit, vital for Bitcoin’s network integrity.
- Bitcoin’s dominance as a Schelling Point stems from its recognition, liquidity, and decentralized security.
What Is Game Theory?
Game Theory studies how individuals make interdependent decisions, analyzing outcomes shaped by mutual choices. It’s pivotal for understanding:
- Market price movements.
- Business strategies.
- Psychological drivers of participation (e.g., adopting Bitcoin).
This article explores Game Theory principles in Bitcoin, including Pure Coordination, Schelling Points, and Network Effects.

The Prisoner’s Dilemma: A Foundation
The Prisoner’s Dilemma models a scenario where two individuals choose between cooperation and betrayal, with outcomes as follows:
| Choice | Outcome (Years in Prison) |
|----------------------|-----------------------------------|
| Both Cooperate | 1 year each |
| One Betrays | 0 years (betrayer), 3 years (other) |
| Both Betray | 2 years each |
Nash Equilibrium: Both prisoners betray, reflecting rational self-interest despite worse collective outcomes.
Real-World Insight:
- Markets often prioritize competition over implicit trust.
- Bitcoin’s design incentivizes cooperation (e.g., miners validating transactions).
Pure Coordination vs. Prisoner’s Dilemma
Unlike betrayal-driven scenarios, Pure Coordination focuses on alignment for mutual gain. In Bitcoin:
- All participants share incentives (e.g., price appreciation via scarcity).
- Network rules ensure consensus (e.g., proof-of-work).
Example: Bitcoin holders benefit collectively by maintaining protocol integrity.
Schelling Points: Bitcoin’s Focal Role
A Schelling Point is a default choice in decentralized decision-making. Bitcoin exemplifies this through:
- Recognition: First-mover advantage.
- Network Effects: Growing adoption reinforces value.
- Decentralization: Trustless security.
- Liquidity: High tradability.
Case Study: US drivers default to the right-hand side—similarly, Bitcoin becomes the "obvious" crypto choice.

Bitcoin as a Coordination Game
Bitcoin’s Nash Equilibrium:
- Users/miners prefer Bitcoin due to widespread adoption.
- Switching costs (e.g., lost network effects) deter alternatives.
Lindey Effect: Bitcoin’s 14-year existence predicts longer future resilience.
Sunk Costs: Investments (time, energy) deepen stakeholder commitment (e.g., mining hash rate).
Case Study: Bitcoin vs. Bitcoin Cash (2017 Fork)
Conflict: Scalability solutions—big blocks (BCH) vs. SegWit (BTC).
Game Theory Outcome:
- Defection: BCH supporters forked.
- Coordination: Majority stayed with BTC, reinforcing its Schelling Point status.
Lesson: Decentralized systems resolve conflicts via consensus-or-fork.
FAQs
1. How does Game Theory apply to Bitcoin?
It models strategic interactions among holders, miners, and developers, emphasizing cooperation for network security.
2. Why is Bitcoin a Schelling Point?
Its liquidity, recognition, and decentralization make it the default "focal" cryptocurrency.
3. What’s the Lindy Effect’s role?
Bitcoin’s longevity suggests future stability, enhancing trust.
4. How do sunk costs impact Bitcoin adoption?
Early adopters benefit from network effects, making alternatives less attractive.
Conclusion
Bitcoin’s Game Theory dynamics—Schelling Points, Pure Coordination, and sunk costs—explain its dominance. As Michael Saylor notes:
"Everybody gets Bitcoin at the price they deserve."
Participation Choice: Engage early or face steeper entry barriers later.
