Introduction
Bitcoin, often hailed as a revolutionary digital currency, has sparked debates about its potential to replace traditional fiat currencies. However, according to Wang Yongli, former Vice President of the Bank of China and senior researcher at the Renmin University of China's Chongyang Institute for Financial Studies, Bitcoin fundamentally operates as a community or commercial circle currency rather than a true monetary replacement.
Key Takeaways:
- Bitcoin mimics gold's scarcity but fails to address modern monetary needs.
- Community currencies rely on network activity, not intrinsic value.
- Blockchain technology must solve real-world problems to be viable.
1. The Monetary Evolution: Why Bitcoin Falls Short
The Role of Currency Stability
Historically, currencies evolved from commodity-based systems (e.g., gold) to fiat systems backed by sovereign trust. The critical function of money—value measurement—requires stable purchasing power. Bitcoin's fixed supply (21 million coins) contrasts with dynamic economies, leading to deflationary pressures and volatility.
"Money must correspond to a nation’s wealth to maintain stability. Bitcoin’s design ignores this fundamental principle." —Wang Yongli
The Fiat Advantage
- Adjustability: Central banks manage inflation (~1–3%) to stimulate growth.
- Sovereign Backing: Legal frameworks tie currencies to national wealth.
- Bitcoin’s Shortfall: No mechanism to align supply with economic growth.
Table: Bitcoin vs. Fiat Currency
| Feature | Bitcoin | Fiat Currency |
|---|---|---|
| Supply Control | Fixed (2100M) | Adjustable |
| Stability | High volatility | Managed inflation |
| Backing | None (community trust) | Sovereign legal systems |
2. Bitcoin’s Practical Limitations
The "Death Coin" Problem
An estimated 3.7–3.8 million Bitcoin are permanently lost due to forgotten private keys, reducing effective circulation. This scarcity exacerbates hoarding over transactional use.
Community Currency Realities
Bitcoin functions best within closed ecosystems (e.g., niche online communities). Without broader utility:
- No Intrinsic Value: Price depends on speculation, not productivity.
- Stablecoins’ Illusion: Pegging to fiat (e.g., USD) turns crypto into tokens, not currencies.

3. Rethinking Blockchain Beyond Bitcoin
The "Impossible Trinity"
Blockchain projects often struggle to balance:
- Decentralization
- Scalability
- Security
Wang argues that pragmatic compromises are needed—especially for central bank digital currencies (CBDCs), which must prioritize legal compliance over decentralization.
Real-World Applications
Blockchain’s potential lies in:
- Digital Identity: Tamper-proof records for licenses/contracts.
- Supply Chains: Transparent, traceable logistics.
- Regulated Tokenization: Asset-backed securities (e.g., STOs).
"Blockchain must solve tangible problems, not chase ideological purity." —Wang Yongli
FAQ Section
Q: Can Bitcoin achieve mass adoption as money?
A: Unlikely—its deflationary design discourages spending, and volatility undermines trust.
Q: Are stablecoins a solution?
A: They’re a stopgap, relying on fiat backing. True innovation requires native utility.
Q: What’s the future of blockchain?
A: Focus on regulated, problem-driven use cases, like CBDCs and enterprise solutions.

Conclusion
Bitcoin’s legacy as a pioneering digital asset is secure, but its role as a currency is overstated. For blockchain to thrive, developers must pivot from speculative hype to real-world impact—a shift already underway in institutional adoption and CBDC research.
