Introduction
In 2008, a pseudonymous programmer named Satoshi Nakamoto published a groundbreaking whitepaper titled "Bitcoin: A Peer-to-Peer Electronic Cash System" on the cryptography mailing list at metzdowd.com. Initially met with indifference, Bitcoin’s decentralized nature, privacy features, and fixed supply gradually captured global attention, sparking debates about its potential to replace sovereign currencies.
Saifedean Ammous, author of "The Bitcoin Standard", argues that a sound monetary system is foundational to human civilization. Bitcoin was designed to enable borderless value transfer without intermediaries, addressing the age-old challenge of moving value across time and space. While proponents envision Bitcoin as a global reserve currency, skeptics question its ability to meet the three core functions of sovereign money: store of value, medium of exchange, and unit of account. This analysis explores Bitcoin’s viability as a sovereign currency.
1. Store of Value: Scarcity vs. Volatility
Bitcoin’s Supply Mechanics
- Fixed Supply Cap: 21 million BTC, with a current annual inflation rate of ~3.8%.
- Halving Events: Block rewards halve every 210,000 blocks (~4 years), reducing new supply. Post-2020 halving, inflation dropped to ~1.7%, below the Fed’s 2% target.
- Stock-to-Flow (S2F) Model: Measures scarcity using the ratio of existing supply (stock) to annual production (flow). Bitcoin’s S2F ratio has risen from 2 (2008–2012) to 60 (projected 2024), rivaling gold’s scarcity.
Price Implications
The S2F-driven price model suggests:
Bitcoin Price = 0.209 × (S2F Ratio)^3.08However, miner sell pressure (to cover operational costs) and market liquidity constraints can suppress short-term price growth.

Key Takeaway: Bitcoin’s programmable scarcity aligns with long-term value storage, but its volatility remains a hurdle.
2. Medium of Exchange: Liquidity Challenges
Mining Economics
- Hash Rate & Difficulty: As more miners join, the network’s hash rate rises, increasing competition and energy costs. Miners often sell BTC to cover expenses, creating sell-side pressure.
- NVT Ratio: Analogous to P/E ratios, the Network Value-to-Transaction (NVT) metric compares market cap to daily transaction volume. High NVT may signal overvaluation or hodling behavior reducing liquidity.
Transactional Utility
Bitcoin’s throughput (~7 transactions/second) pales versus Visa’s 24,000 TPS, limiting its use for microtransactions. Layer-2 solutions (e.g., Lightning Network) aim to address scalability.
FAQ:
Q: Can Bitcoin handle mass adoption as a payment system?
A: Not in its current form—scaling solutions are critical for everyday use.
3. Unit of Account: The Volatility Problem
Price Stability
Bitcoin’s annualized volatility historically exceeds 100%, compared to ~8% for major fiat currencies. While volatility has trended downward, it remains unsuitable for pricing contracts or salaries.
EWMA Analysis
Exponentially Weighted Moving Average models show volatility could decline to ~20% by 2025, but achieving sub-8% levels (like fiat) requires deeper liquidity and institutional adoption.

Conclusion: A Long Road Ahead
Bitcoin’s path to becoming a sovereign currency hinges on:
- Scarcity-Driven Valuation: Maintaining S2F credibility.
- Scalability: Enhancing transactional capacity.
- Stability: Reducing volatility through liquidity and derivatives markets.
While Bitcoin excels as a censorship-resistant asset, its current limitations prevent direct competition with sovereign currencies. The journey demands technological maturation and broader macroeconomic acceptance.
FAQ:
Q: Will governments ever adopt Bitcoin as legal tender?
A: El Salvador’s 2021 adoption was a landmark, but widespread acceptance requires regulatory clarity and infrastructure.
Q: How does Bitcoin’s energy use impact its currency potential?
A: Proof-of-work mining raises sustainability concerns—alternatives like PoS may offer greener models.
