In the previous article, we examined the origins of the early 21st-century internet bubble and its lasting impact—drawing clear parallels to today’s booming interest in cryptocurrencies, the metaverse, and NFTs. These innovations emerged amid low interest rates and abundant liquidity, but now face a harsh environment of rising rates and economic contraction. As technological bubbles burst and restructure, concerns grow that blockchain-based assets may follow a similar fate. In this part, we shift focus from technology to economics—analyzing whether cryptocurrency truly meets the definition of money by examining its function, attributes, and real-world applicability.
Is Cryptocurrency Real Money?
Despite being called “currency,” cryptocurrencies like Bitcoin, Ethereum, and Dogecoin remain controversial in financial and academic circles. Proponents argue that Bitcoin is “sound money”—a decentralized, inflation-resistant alternative to fiat currencies. Some even envision it as a future global standard. But when evaluated against the core functions and essential attributes of money, current digital currencies fall significantly short.
The Three Core Functions of Money
Money serves three primary roles: medium of exchange, store of value, and unit of account.
Medium of Exchange
Money simplifies trade by eliminating the inefficiencies of barter. While cryptocurrency can be used for transactions—famously illustrated by the 2010 "Bitcoin pizza" purchase (10,000 BTC for two pizzas)—real-world adoption remains limited. Bitcoin’s network can process only about 7 transactions per second, far below the tens of thousands handled by systems like Visa. High transaction fees and slow confirmation times during peak usage make it impractical for everyday purchases.👉 Discover how modern platforms are optimizing digital asset transactions for speed and scalability.
Moreover, acceptance depends entirely on user trust—not legal mandate. Without government backing or widespread merchant adoption, crypto cannot function reliably as a universal payment method.
- Store of Value
Advocates highlight Bitcoin’s capped supply (21 million coins) as a hedge against inflation, likening it to digital gold. However, extreme price volatility—swinging thousands of dollars in days—undermines its reliability. A store of value must preserve purchasing power over time; crypto’s wild fluctuations make it speculative rather than stable. - Unit of Account
For money to measure worth consistently across goods and services, its value must remain relatively steady. Cryptocurrencies fail here too. Imagine pricing a coffee at 0.0005 BTC one day and 0.0003 the next due to market swings—this unpredictability renders them ineffective as accounting tools.
The Four Essential Attributes of Money
Beyond functions, true money exhibits four key traits: widespread acceptability, value stability, fungibility, and transaction convenience.
- Widespread Acceptability
Less than 1.5% of the global population holds Bitcoin (~114 million out of 8 billion). Ownership is highly concentrated: just 10,000 individuals control roughly one-third of all circulating supply. This elite concentration contradicts the democratic ideal of currency and limits real-world usability. - Value Stability
Bitcoin’s price swings exceed those of stocks, bonds, and even gold. Such volatility discourages spending—why buy a $3 coffee today if your coin could be worth $850 tomorrow? This hoarding behavior further reduces circulation and weakens its monetary utility. - Fungibility
Here, crypto performs well. Like traditional currencies, each unit is interchangeable. Bitcoin can be divided down to eight decimal places (a "satoshi"), enabling microtransactions. - Transaction Convenience
While blockchain enables borderless transfers, technical barriers persist. Wallet setup, private key management, network congestion, and high fees create friction—especially compared to instant bank transfers or mobile payments.
Cryptocurrency vs. Precious Metals
Some compare Bitcoin to gold due to its fixed supply. Both are seen as inflation-resistant stores of value. Yet history shows that commodity-backed money has limitations. Gold’s scarcity led to deflationary pressures during economic growth, stifling investment and consumption.
Similarly, Bitcoin’s algorithmically limited issuance ignores real economic demand. If adopted as a base currency, its rigid supply could trigger chronic deflation—discouraging spending and amplifying recessions. Furthermore, holders’ expectation of appreciation incentivizes speculation over usage, undermining the very essence of money: circulation.
Cryptocurrency vs. Modern Fiat Currency
Fiat money—like the US dollar or euro—is state-issued legal tender backed by national credit, not physical commodities. Its value stems from institutional trust, regulatory enforcement, and macroeconomic management.
The defining feature of crypto—decentralization—is also its greatest obstacle to replacing fiat systems.
- Lack of Trust and Regulation
No central authority governs Bitcoin. While this appeals to anti-establishment sentiments post-2008 crisis, it also means no entity guarantees value or resolves disputes. Anyone can create a new coin, fueling scams and volatility. - No Monetary Policy Tool
Central banks adjust money supply to manage inflation, unemployment, and growth. Crypto lacks this flexibility. Its fixed rules prevent counter-cyclical responses during crises—a critical flaw in modern economic governance.
As long as nation-states exist and manage economies through monetary policy, state-backed currencies will remain dominant. Decentralized tokens may coexist as niche assets—but not replacements.
Frequently Asked Questions
Q: Can cryptocurrency ever become legal tender?
A: Only if governments regulate and adopt it within existing financial frameworks—like El Salvador did with Bitcoin. However, most nations prioritize monetary sovereignty and stability over decentralization.
Q: Why do people treat crypto like money if it doesn’t function as one?
A: Speculation drives perception. Media hype and early gains create an illusion of utility. But without consistent use in daily transactions, it remains an investment vehicle—not currency.
Q: Does blockchain technology have value even if crypto isn’t real money?
A: Absolutely. Blockchain’s potential in supply chains, identity verification, and smart contracts is significant. The tech may revolutionize industries—even if its first application (cryptocurrency) is overhyped.
Q: Is energy consumption a valid concern for crypto?
A: Yes. Proof-of-work mining consumes vast electricity—comparable to small countries. While some projects shift to greener models (e.g., proof-of-stake), environmental costs remain a major criticism.
Q: Could a central bank digital currency (CBDC) bridge the gap?
A: CBDCs combine digital efficiency with state backing—offering faster payments without sacrificing control. They represent the future of digital money more realistically than decentralized cryptos.
Final Thoughts: Bubble, Asset, or Future Standard?
Cryptocurrency emerged from distrust in traditional finance after the 2008 crisis. Its promise of decentralization and scarcity resonated globally. Yet decades later, it still fails basic monetary tests. It's too volatile to spend, too concentrated to democratize, and too rigid to manage economies.
Like past tech booms—from railroads to dot-coms—crypto shows classic signs of speculation outpacing utility. Blockchain may yet transform industries, just as the internet eventually fulfilled its promise after the early 2000s crash. But today’s most prominent use cases—trading, NFTs, DeFi—are largely financialized rather than foundational.
Environmental concerns, regulatory scrutiny, and illicit use further cloud its legitimacy. And while innovation continues, we must remember: "This time is different" has rarely been right in financial history.

Cryptocurrency may evolve into a legitimate asset class—like art or commodities—but not into mainstream money. The future belongs not to those who confuse hype with function, but to those who build real-world value on solid technological ground.
