The history of money has evolved through several distinct phases: the pre-coinage era, the coinage era, the bank money era, and now, the emerging digital currency era. Just as coinage theories cannot fully explain bank money practices, applying coinage or bank money doctrines to digital currency practices is equally inadequate.
Recently, criticisms against cryptocurrencies (or crypto-assets) have intensified. Central bankers, financial regulators, market participants, and academics have raised two core objections:
- Do crypto-assets possess intrinsic "value"?
- Can their rising prices alone validate this value?
At the heart lies the question of value—without it, claims of "monetary" attributes or price foundations collapse. This demands a rigorous examination: Do crypto-assets hold value, and if so, where does this value originate?
Are Crypto-Assets "Money"?
When former Fed Chair Ben Bernanke was asked about Bitcoin, he replied, "It’s not under my regulation." This evasion underscores a legal reality: no universal law defines "money." While the U.S. Constitution grants Congress (via the Fed) exclusive currency issuance rights, it doesn’t specify what constitutes money. Thus, from a legal standpoint, Bitcoin and similar assets aren’t "money." But what about their functional attributes?
Theoretical Definitions of Money
Academic sources like The Palgrave Dictionary of Money and Finance avoid defining "money" directly, instead describing its roles in economic life. Economics textbooks similarly sidestep explicit definitions, focusing on central banking perspectives (e.g., monetary aggregates) or modern "bank money."
Historically, monetary theories shifted with monetary forms:
- Political economy (coinage era): Emphasized money’s four functions: unit of account, medium of exchange, store of value, and international currency.
- Monetary banking (bank money era): Focused on credit systems and central banking.
Applying outdated theories to crypto-assets is flawed—digital currencies require new frameworks.
The "Value" Attribute of Money: A Philosophical and Economic Inquiry
"Value" originated in political economy as a meta-concept. Key schools debated its nature:
- Mercantilists: Equated value with precious metals (wealth = tangible assets).
- Physiocrats (e.g., Quesnay): Argued value derived from land (wealth = agricultural output).
- Classical economists (Smith, Ricardo, Marx): Championed labor theory of value, linking value to production effort.
Modern economics abandoned these philosophical debates, prioritizing price mechanisms over value metaphysics. Yet, crypto-assets resurrect these questions by challenging traditional value anchors.
Can Crypto-Assets Fulfill Money’s Value Criteria?
Critics argue crypto-assets lack value because they:
- Aren’t consumable goods/services ("virtual" = "valueless").
- Lack physical backing (unlike gold or equities).
Proponents counter that their value emerges from:
- Digital utility: Functionality within native ecosystems (e.g., Ethereum’s smart contracts).
- Exchangeability: Convertibility to fiat currencies or goods (e.g., the 2010 "Bitcoin Pizza" transaction).
However, exchangeability ≠ monetary value. While crypto-assets can trade at high prices (like commodities), this doesn’t confer "money" status. True monetary value requires cross-community acceptance as a digital currency—a status still evolving.
Key Takeaways: Crypto-Assets’ Value vs. Monetary Potential
- Value Exists, But Isn’t Monetary: Crypto-assets derive value from digital ecosystem utility, not traditional monetary attributes.
- Price ≠ Value: Market demand drives prices, but this reflects speculation, not intrinsic worth.
Path to Moneyhood: To become "money," crypto-assets must achieve:
- Universal acceptance beyond niche communities.
- Stability as a unit of account and store of value.
FAQs
Q1: Can Bitcoin replace fiat currencies?
A1: Not currently. Its volatility and limited adoption hinder core monetary functions like price stability.
Q2: What gives crypto-assets value if not physical backing?
A2: Network effects, scarcity (e.g., Bitcoin’s 21M cap), and ecosystem utility (e.g., DeFi applications).
Q3: Are stablecoins "money"?
A3: Closer—they peg value to fiat currencies, enhancing stability, but regulatory recognition remains key.
Q4: Why do central banks oppose private cryptocurrencies?
A4: They threaten monetary sovereignty and lack consumer protections (e.g., deposit insurance).

Conclusion: Crypto-assets are pioneering digital value systems, but labeling them "money" prematurely ignores centuries of monetary evolution. Their future hinges on bridging digital utility with real-world trust—a journey just beginning.
