The debate over whether cryptocurrencies like Bitcoin can replace traditional fiat money has intensified over the past decade. While many enthusiasts hail Bitcoin as the future of global finance, leading financial experts remain skeptical. Among them is Wang Yongli, former vice president of the Bank of China and senior researcher at the Renmin University Chongyang Institute for Financial Studies. In a keynote speech delivered on the 10th anniversary of Bitcoin’s creation, Wang offered a compelling analysis grounded in monetary history, technological limitations, and economic logic—concluding that Bitcoin cannot disrupt or replace sovereign currencies.
Why Bitcoin Fails as a True Currency
At its core, a currency must serve as a stable measure of value. This foundational principle has guided the evolution of money—from commodity-based systems (like gold and silver) to today’s fiat and credit-based monetary systems. Wang emphasizes that the key to maintaining economic stability lies in aligning the total supply of money with the scale of legally protected, monetizable wealth within a nation's jurisdiction.
Bitcoin, however, operates under a rigid algorithmic cap: only 21 million bitcoins will ever exist. While this scarcity is often praised, it contradicts the dynamic nature of modern economies. As national wealth grows, an inflexible money supply leads to deflationary pressure—a scenario where prices fall continuously, discouraging investment and consumption. Historically, such deflation has led to economic stagnation and social unrest.
Moreover, unlike fiat currencies backed by real assets and government authority, Bitcoin lacks intrinsic backing. It does not represent ownership of tangible value nor is it tied to any legal or economic framework. Instead, its value stems purely from market speculation and network adoption—making it highly volatile and unsuitable as a reliable store of value or medium of exchange.

The Myth of Decentralization and Real-World Utility
Bitcoin’s design prioritizes decentralization and immutability, creating a closed, self-contained network. While these features enhance security within the system, they severely limit practical applications in the real world. For instance:
- Transactions lack identity verification—users are pseudonymous, making trust-based commerce difficult.
- There’s no mechanism to link Bitcoin directly to physical assets like property, contracts, or services.
- Its use cases remain narrow: primarily speculative trading, peer-to-peer transfers (in limited jurisdictions), and fundraising via ICOs or STOs.
Wang argues that true blockchain innovation must move beyond this isolated model. A blockchain that cannot interact securely with real-world data, institutions, or legal frameworks cannot solve meaningful problems in finance, governance, or supply chains.
Furthermore, the energy-intensive mining process required to maintain Bitcoin’s network raises sustainability concerns. The environmental cost of proof-of-work mechanisms further undermines claims of long-term viability.
From Hype to Reality: Rethinking Blockchain’s Value
In 2017, Bitcoin’s price surged from around $1,300 to nearly $20,000—fueling dreams of a decentralized financial revolution. But by 2018, the bubble burst. Prices plummeted, investor enthusiasm waned, and many projects failed to deliver functional applications.
This cycle reveals a critical flaw: many blockchain initiatives prioritize token creation over problem-solving. Launching a coin through an ICO became synonymous with innovation—even when no real use case existed. Wang warns that this approach reverses cause and effect. Value should emerge from utility—not speculation.
Instead, he advocates for a shift in focus:
- Use blockchain to digitize and secure government records (licenses, contracts, deeds).
- Enhance transparency in public services and charitable activities.
- Streamline financial settlements and reduce fraud in securities trading.
These applications leverage blockchain’s strengths—immutability, traceability, and tamper resistance—without requiring a new currency.
The Role of Stablecoins and Regulatory Clarity
Recognizing Bitcoin’s volatility, developers introduced stablecoins pegged 1:1 to fiat currencies like the U.S. dollar. While these tokens enable more predictable transactions in digital environments, Wang points out a crucial reality: they are not independent currencies. They derive value entirely from their linkage to traditional money—effectively functioning as digital vouchers rather than true alternatives.
This reinforces his central argument: any digital currency aiming for widespread adoption must operate within—or at least interoperate with—the existing financial infrastructure. Complete脱离 from sovereign monetary systems is neither feasible nor desirable.
Regulators also play a vital role. Digital assets used beyond closed ecosystems must be subject to oversight—especially when interfacing with fiat currencies. Key safeguards include:
- Mandatory real-name registration for digital wallets.
- Controlled gateways between fiat and digital asset platforms.
- Clear boundaries defining where and how digital tokens can be used.
Without such frameworks, digital currencies risk enabling financial instability or circumventing monetary policy.

FAQ: Common Questions About Bitcoin and Blockchain
Q: Can Bitcoin ever replace national currencies?
A: No. Due to its fixed supply and lack of macroeconomic adaptability, Bitcoin cannot support large-scale economies. Central banks require flexibility to manage inflation, employment, and growth—something Bitcoin’s design explicitly prevents.
Q: Is blockchain technology still valuable if Bitcoin isn’t?
A: Absolutely. Blockchain’s true potential lies in secure data management—not currency creation. Applications in identity verification, supply chain tracking, and smart contracts offer transformative benefits across industries.
Q: Are all cryptocurrencies just speculative bubbles?
A: Many early projects were driven by hype, but mature ecosystems are emerging. Projects focused on real utility—such as tokenized assets or decentralized identity—are building sustainable value over time.
Q: What should governments do about digital currencies?
A: Regulate thoughtfully. Ban speculative misuse but encourage innovation in regulated environments. Support central bank digital currencies (CBDCs) that enhance financial inclusion without undermining monetary control.
Q: Can decentralized finance (DeFi) succeed without replacing fiat?
A: Yes. DeFi can coexist with traditional finance by offering alternative lending, savings, and trading mechanisms—all while interfacing with regulated financial systems.
Q: Why did so many people believe Bitcoin would change everything?
A: Its timing coincided with distrust in banks after the 2008 crisis. Combined with rapid price gains and compelling narratives about decentralization, it captured imaginations—but confused technological novelty with systemic transformation.
Moving Forward: A Practical Path for Blockchain
Wang calls for a reset in how we view blockchain innovation. Rather than chasing decentralization at all costs, developers should ask: Does this solve a real problem? The most impactful applications will integrate seamlessly with existing systems—not attempt to overthrow them.
Central banks should not mimic Bitcoin’s mining model when developing digital currencies. Instead, central bank digital currencies (CBDCs) should be seen as digital versions of national money—enhanced by smart technology for efficiency and accessibility.
Ultimately, blockchain’s promise lies not in replacing trust but in reinforcing it through transparency. The future belongs not to isolated networks, but to interoperable systems that serve people, businesses, and governments alike.
