In a world increasingly defined by technological innovation, cryptocurrency has emerged as a phenomenon capturing the imagination of tech enthusiasts, financial experts, and the general public. Proponents of digital currencies claim they will revolutionize the financial industry.
Imagine a world where financial transactions occur seamlessly and often anonymously, bypassing the limitations of traditional banking systems and fiat currencies. This is the grand vision of cryptocurrency.
Undoubtedly, the technology behind digital currencies holds significant potential. But can the concept of a decentralized, borderless financial system truly materialize? Although it has gained popularity and disrupted traditional finance to some extent, concerns remain—especially regarding its long-term stability and security.
The Promises and Realities of a Borderless Financial System
The fundamental premise of cryptocurrency is to replace trust with technological mechanisms. This promotes the idea that “code is law,” creating a self-regulating framework free from human bias and error. The primary guarantee, at least in theory, is the elimination of trusted intermediaries. This was the core idea presented in the original Bitcoin whitepaper—an encrypted solution enabling direct transactions between parties without the need for financial institutions or third-party intermediaries.
However, does the cryptocurrency industry truly remove traditional intermediaries, or does it simply replace them with new ones? Some experts argue that crypto-based financial systems may exacerbate many issues inherent in traditional banking. According to Kadan Stadelmann, CTO of Komodo, this is already happening.
“Right now, the average crypto user’s experience is closer to traditional finance. For instance, many people rely on trust-based centralized cryptocurrency exchanges to hold and trade digital assets. These platforms operate similarly to banks but expose users to far greater risks.”
- Kadan Stadelmann, CTO of Komodo
Initially, the concept of cryptocurrency aimed to establish a decentralized payment infrastructure based on blockchain technology. While some believe this goal is achievable, the complex challenges of implementing such a system make it seem nearly impossible.
Tim O’Reilly, CEO of O’Reilly Media, notes that Web3—often hailed as the next evolution of the internet—is just one of many efforts to establish decentralized systems in the tech world. Compared to its predecessors, Bitcoin underwent rapid centralization, currently relying on a limited group of software developers and mining pools to sustain its operations.
“Blockchain has turned out to be the fastest re-centralizing technology I’ve ever seen in my life. With personal computers, it took a decade to re-centralize. With the web, it took a decade. But with Bitcoin, it only took a few years for most of the value to be held by a small number of people.”
- Tim O’Reilly, CEO of O’Reilly Media, Inc.
An International Monetary Fund (IMF) report authored by Hilary Allen indicates that voting rights in decentralized autonomous organizations (DAOs) and wealth accumulation in the crypto space are often more concentrated than in traditional financial systems. Moreover, decentralized blockchain technology struggles to efficiently process large volumes of transactions and lacks mechanisms for reversing transactions. This has led to the emergence of intermediaries seeking to simplify cumbersome decentralized services for users, often motivated by profit.
Economists at the Bank for International Settlements (BIS) assert that the cryptocurrency space is characterized by a “decentralization illusion,” largely due to the unavoidable need for centralized governance and the tendency of blockchain consensus mechanisms to concentrate power. This raises important questions about the true level of decentralization within the crypto ecosystem.
Notably, while some crypto enterprises claim to embody decentralization, many do not uphold this principle in practice. Centralized exchanges, wallet providers, stablecoin issuers, and various other intermediaries play critical roles in the crypto ecosystem. Some of these entities operate without regulatory oversight, raising concerns about consumer protection and financial stability—issues reminiscent of those in traditional finance.
Understanding Cryptocurrency Failures
Data from CoinKickoff provides insights into failed cryptocurrencies, detailing the years they ceased to exist and when they were initially launched. This information spans a decade of crypto downturns, covering the period from 2013 to 2022.
Unfortunately, the failure of many projects reveals a sobering truth: intermediaries often wield significant influence and control over these supposedly decentralized enterprises. This reality shatters the notion of true decentralization and raises doubts about the authenticity of their claims.
According to a Visual Capitalist report, 2018 witnessed the highest number of cryptocurrency failures, with 751 digital currencies becoming obsolete. Of these, 390 coins failed due to insufficient trading volume, while 237 succumbed to fraudulent activities. In subsequent years, cases of regulatory evasion, inadequate risk management, and lack of transparency increased, exposing the vulnerabilities of the crypto ecosystem.
This imitation of traditional finance’s centralized structures also leads to market failures, negative externalities, and vulnerabilities similar to those in conventional financial systems. As reported by Reuters, in 2022 alone, several major cryptocurrency giants—once thought invincible—collapsed or filed for bankruptcy. Notable examples include:
- Celsius Network
- Genesis Global Capital
- Voyager Digital
- Three Arrows Capital
- Core Scientific
- FTX
- BlockFi
What Is the True Cost of Digital Currency?
A significant concern is the substantial negative impact of cryptocurrencies, including excessive energy consumption. The lack of adequate regulation and consumer protection in the crypto industry leaves users vulnerable to hacks and scams. Meanwhile, the proof-of-work validation mechanism used by Bitcoin and other cryptocurrencies consumes vast amounts of energy, raising environmental concerns.
According to Earthjustice, Bitcoin’s energy consumption reached a staggering 36 billion kilowatt-hours (kWh) as of July 2022. To put this惊人的 number into perspective, it equates to the total electricity consumption of four U.S. states—Maine, New Hampshire, Vermont, and Rhode Island—during the same period.
The explosive growth of the cryptocurrency industry has placed enormous strain on energy grids, driven up retail electricity prices, and contributed to increased carbon emissions and local air pollution. These consequences raise critical environmental and social questions, necessitating closer scrutiny of the industry’s practices and their impact on the broader energy landscape.
Furthermore, the complexity and potential for manipulation within the crypto ecosystem make it prone to volatile boom-and-bust cycles. One of the most notable examples is Bitcoin’s price surge to nearly $20,000, followed by a dramatic crash that saw its value plummet. Similar cycles have been observed with other cryptocurrencies. These price fluctuations can create market instability and lead to significant losses for investors who buy during market peaks.
The speculative nature of cryptocurrency exacerbates these issues. Many investors and traders purchase digital assets hoping for quick profits as prices rise. This can lead to overvalued markets and bubbles. When hype subsides or negative news affects market sentiment, prices can crash, causing losses for those who entered the market during the speculative phase.
In many cases, profitability in the cryptocurrency market depends on finding new investors willing to buy at higher prices than initial investors paid—a concept often referred to as the “greater fool theory.” Investors believe they can always sell their assets to someone else at a higher price. However, when the influx of new investors slows, prices may stagnate or fall, resulting in potential losses for those who bought at elevated levels.

Can Cryptocurrency Fulfill Its Grand Vision?
While cryptocurrency advocates often claim that digital currencies have the potential to promote financial inclusion, the World Economic Forum has expressed a different perspective on the relationship between financial inclusion and crypto. Although acknowledging that financial inclusion is an important issue, the forum suggests that cryptocurrency may not be the ultimate solution to the underlying political and technical challenges involved. The group notes that digital currencies, in their current implementation, may not offer significant new advantages for financial inclusion beyond what traditional financial options already provide.
Hilary Allen, a professor at American University Washington College of Law whose research focuses on the impact of new financial technologies on financial stability, states:
“Crypto has failed to deliver on its promises of decentralization, and if integrated into the traditional financial system, its volatile growth and recession cycles could have significant economic repercussions, potentially disrupting the flow of capital to the real economy.”
— Hilary Allen, Professor at American University Washington College of Law
It is essential to recognize that cryptocurrency is not a magical solution to all economic challenges. While it offers potential benefits, it is important to understand that digital currencies alone cannot swiftly resolve the complexities of financial markets.
As we explore the future of digital currencies, a balanced perspective is crucial. Only through a pragmatic approach can we hope to unlock the true potential of cryptocurrency within the dynamic landscape of the financial world.
