Blockchain technology, originating from Bitcoin, has given rise to numerous cryptocurrencies over the past decade. These digital assets have generated widespread attention due to sensational stories of rapid wealth accumulation. This has led to a common misconception that cryptocurrencies represent the future of global money and are guaranteed to appreciate in value.
Many cryptocurrency advocates promote the idea that these assets will eventually replace sovereign fiat currencies, creating a completely decentralized, anonymous international monetary system that requires no government backing or asset collateral. In recent years, however, central banks and major tech corporations like Facebook have introduced stablecoins—digital currencies pegged to traditional assets—which have begun limited testing.
With blockchain technology gaining strategic importance in national policies worldwide, public interest has surged. Yet the overwhelming amount of mixed and misleading information has made it difficult to distinguish between blockchain applications, cryptocurrencies, and stablecoins.
Understanding the Technical Foundation
Both stablecoins and cryptocurrencies are applications built on blockchain technology. Blockchains generally fall into two categories: public chains and permissioned chains.
Public chains are characterized by:
- Complete decentralization
- User anonymity
- Transparent transaction histories
Most cryptocurrencies operate on public chains. Under current regulations in many countries, including China, public chain applications often fail to meet compliance requirements and cannot operate legally within these jurisdictions.
In contrast, most stablecoins that are pegged to fiat currencies utilize permissioned chain architectures. These systems:
- Are not fully decentralized
- Allow for government oversight through legal and technical means
- Enable regulators to engage with issuing organizations
For example, governments can summon Facebook to hearings regarding its Libra stablecoin project and establish appropriate regulatory frameworks. This level of oversight is impossible with Bitcoin and other decentralized cryptocurrencies, where no central authority exists to hold accountable.
The Fundamental Nature of Money
To understand whether stablecoins and cryptocurrencies qualify as money, we must examine their financial attributes through the lens of monetary history.
Money has existed since the earliest formations of human societies. When a universal item emerged to facilitate trade beyond simple barter systems, the first prototypes of money began to take shape. Money has evolved through two broad historical phases: commodity money and fiat money.
Commodity money possessed intrinsic value based on the material from which it was made, such as precious metals used in coins. During this era, governments didn't necessarily maintain absolute monopoly over currency issuance. In ancient China, for example, private citizens could mint coins provided they met official standards for weight and composition.
As human societies developed and economic activities grew more complex, the limitations of commodity money became apparent. Issues with distribution, circulation, portability, storage, and transaction efficiency ultimately led to the emergence of fiat money.
Fiat currency derives its value primarily from government regulation and legal decree. Banknotes and digital entries that possess minimal intrinsic value are declared legal tender through sovereign power. Today, most global monetary systems operate on this fiat principle, with national credit backing the difference between face value and actual material worth.
Are Cryptocurrencies Really Money?
Cryptocurrencies position themselves as "currencies," but do they truly function as money? First, they clearly don't qualify as commodity money since they exist purely as digital code without any intrinsic physical value. Their advocated decentralization also prevents them from serving as any nation's fiat currency.
Some proponents argue that cryptocurrencies represent a new form of money—an upgraded version of sovereign-backed fiat currency. This perspective, however, lacks substantive economic foundation. When we return to money's most basic function, we can better assess cryptocurrencies' true nature.
The fundamental property of genuine money is that when it changes hands, it typically facilitates the purchase of goods or services (including lending relationships). Currently, 99.999% of cryptocurrency transactions do not involve goods or services but instead represent new holders accumulating digital assets in hopes of selling them later at a profit.
Without this essential monetary function, we must conclude that cryptocurrencies do not currently function as actual money. What are they then? Financially literate readers may recognize that cryptocurrencies share identical properties with stocks—they are financial products with investment characteristics.
Cryptocurrencies as Investment Vehicles
Viewing cryptocurrencies as investment assets makes many observed behaviors much easier to explain. Investment decisions are inherently subjective, with each individual applying their own valuation standards and methodologies. People invest in stocks, antiques, stamps, and even sneakers.
However, most investment vehicles—like commodity money—possess some intrinsic value. Sneakers can be worn, stamps can mail letters, and stocks represent claims on company assets, cash flows, and future earnings. Cryptocurrencies, by contrast, possess no inherent value and aren't backed by any physical commodities.
Even the so-called "mining costs" associated with cryptocurrency creation are expended as operational expenses rather than being embedded within the digital assets themselves. As investment vehicles, cryptocurrencies qualify as 100% speculative instruments. This explains why Warren Buffett has consistently expressed skepticism about cryptocurrencies—their purely speculative nature directly contradicts his value investing philosophy.
Speculative investments represent a relatively niche segment of financial markets. Their value maintenance depends on two critical factors:
- Current participant confidence
- The ability to attract new investors
As long as new investors continue entering the market, purely speculative assets can maintain or even increase their value. Consequently, cryptocurrency issuers primarily focus on marketing strategies, positioning their offerings as monetary instruments, technological breakthroughs, and guaranteed appreciation vehicles—all while avoiding substantive discussions about actual utility.
This approach often targets financially inexperienced individuals and shares concerning similarities with marketing tactics aimed at vulnerable populations.
Stablecoins: True Digital Currencies
In contrast to cryptocurrencies, stablecoins like Facebook's Libra (now Diem) and various government-backed digital currencies are pegged to existing fiat currencies. These are genuinely tokenized representations of traditional money.
Once stablecoins achieve widespread adoption, nobody will purchase them specifically for investment purposes. Those seeking foreign exchange exposure would simply buy the actual currencies rather than involving potentially fee-heavy stablecoin intermediaries. Thus, stablecoin transactions will primarily facilitate goods and services exchanges—making them truly monetary in function.

Key Differences Summarized
Stablecoins and cryptocurrencies differ fundamentally in their essential nature:
- Stablecoins possess monetary attributes
- Cryptocurrencies exhibit investment characteristics
Despite sharing underlying blockchain technology, these two financial products belong to completely different categories and shouldn't be directly compared.
Future Possibilities and Realistic Expectations
Some might argue that even if cryptocurrencies currently function as investments, they could eventually achieve mainstream acceptance and replace sovereign fiat currencies as truly decentralized global money.
While not entirely impossible, this transformation would require:
- Fundamental evolution of human society
- Unimaginable advances in productive capabilities
- Complete restructuring of social organization
Under such conditions, money might not require national credit backing. However, within any foreseeable future, the possibility of speculative investment assets becoming global currencies approaches zero—perhaps even less likely than sneakers achieving monetary status.
Frequently Asked Questions
What is the main difference between stablecoins and cryptocurrencies?
Stablecoins are digital assets pegged to traditional fiat currencies or commodities, designed to maintain stable value for transactions. Cryptocurrencies are decentralized digital assets that typically experience significant price volatility and function primarily as investment vehicles rather than mediums of exchange.
Can cryptocurrencies become widely accepted as money?
While theoretically possible, widespread adoption of cryptocurrencies as money would require fundamental changes to global economic systems and societal structures. Their current price volatility and speculative nature make them unsuitable for everyday transactions in the present economic environment.
Are stablecoins regulated differently from cryptocurrencies?
Yes, stablecoins typically fall under greater regulatory scrutiny because they emulate traditional currencies and often have identifiable issuing organizations. Cryptocurrencies operating on public blockchains present greater regulatory challenges due to their decentralized nature.
Why do governments prefer stablecoins over cryptocurrencies?
Governments generally favor stablecoins because they can be designed to comply with existing financial regulations, allow for oversight and control, and maintain stability through their peg to traditional assets—unlike volatile cryptocurrencies that operate outside conventional regulatory frameworks.
Do all stablecoins use permissioned blockchains?
While most fiat-backed stablecoins utilize permissioned architectures to enable regulatory compliance, some stablecoins may operate on public blockchains with varying degrees of decentralization. The specific technical implementation depends on the issuer's requirements and regulatory environment.
How can investors distinguish between speculative cryptocurrencies and legitimate blockchain projects?
Legitimate blockchain projects typically solve concrete problems, have transparent development roadmaps, and engage with regulatory bodies. Purely speculative cryptocurrencies often emphasize price appreciation over utility and may employ aggressive marketing tactics while providing limited technical information.
