Digital currencies have experienced rapid development over the past decade. Recently, Facebook's announcement of its cryptocurrency project, Libra, has reignited global interest in digital currencies. While digital currencies fulfill certain monetary functions, factors such as price volatility, cybersecurity risks, regulatory gaps, and the absence of state backing limit their role to a supplementary one within the modern monetary system rather than a replacement.
Digital currencies significantly impact:
- Monetary supply and demand structures
- Financial inclusion
- Existing payment systems
They also introduce new possibilities for:
- Creating a supranational international currency
- Reforming the global monetary system
Proactive measures are essential, including:
- Central bank digital currency (CBDC) research and issuance
- Encouraging private-sector innovation
- Risk control and regulatory improvements
Evolution of Digital Currencies
In early 2009, Bitcoin—a decentralized, peer-to-peer digital currency—emerged, bringing blockchain technology into mainstream awareness. Over the past decade, advancements in internet and blockchain technologies have transformed global finance and payment models, making virtualized currency issuance a focal point for both academia and industry.
Key Innovations and Debates
- Digital currencies challenge traditional monetary theories and payment methods (Xie Ping & Shi Wuguang, 2015).
Ongoing discussions revolve around:
- The nature of digital currencies
- Their potential as sovereign or supranational currencies
- Regulatory frameworks
Facebook’s Libra (2019)
Libra introduced notable improvements:
- Stability: Backed by a basket of bank deposits and short-term government bonds (primarily USD).
- Supranational Potential: Similar to IMF’s Special Drawing Rights (SDR), but possibly excluding the Chinese yuan.
Classification of Digital Currencies
By Interaction with Real Economy (ECB, 2012)
| Type | Description | Examples |
|------|------------|----------|
| Closed Virtual Currencies | No link to real economy; used only within virtual communities | World of Warcraft Gold |
| Unidirectional Virtual Currencies | Purchasable with fiat money; limited to virtual/goods services | QQ Coins, Facebook Credits |
| Bidirectional Virtual Currencies | Tradable with fiat money; usable for real/virtual transactions | Bitcoin, Ethereum |
By Issuer
- Private Digital Currencies: Bitcoin, Ethereum, Libra
- Central Bank Digital Currencies (CBDCs): Under development by multiple governments.
Current Challenges
1. Price Volatility
- Bitcoin’s value fluctuated by 825% (2017) and dropped 204% (2018).
- Libra’s Stability Risks: Tied to sovereign currencies (USD, EUR), which are inherently unstable.
2. Cybersecurity Threats
- High-profile hacks (e.g., $27M theft from Japanese exchanges, 2019).
- Regulatory scrutiny over data privacy and network security.
3. Regulatory Gaps
- Anonymity facilitates illegal activities (e.g., 25% of Bitcoin users linked to illicit transactions).
- G7 Opposition: Libra must comply with anti-money laundering (AML) rules before launch.
Can Digital Currencies Become Supranational?
Potential Impacts
- Monetary Systems: Alters fiat currency demand/supply dynamics.
- Financial Inclusion: Reduces costs for unbanked populations (2B adults globally).
- Payments: Challenges SWIFT with faster, cheaper transactions.
Libra’s Supranational Prospects
- Global Reach: Facebook’s 2B+ users enable rapid adoption.
- Currency Basket: Mimics SDR but may sideline smaller economies’ currencies.
Political Hurdles
- State Sovereignty: Monetary power reflects geopolitical influence.
- USD Dominance: Current system favors USD (61.82% of global reserves).

Strategic Recommendations
1. Accelerate CBDC Development
- China’s DC/EP Project adopts a two-tier system (central bank → commercial banks → public).
2. Foster Private-Sector Innovation

3. Mitigate Financial Risks
- Address volatility, tax evasion, and loss of monetary policy control.
4. Enhance Regulation
- Domestic Frameworks: AML, user protection.
- Global Cooperation: Combat cross-border illicit flows.
