The extreme volatility and speculative nature of cryptocurrencies like Bitcoin have become defining characteristics of this emerging asset class. As global regulatory scrutiny intensifies, Bitcoin's price has fallen significantly from its December highs, now hovering around $8,400.
Following the global token frenzy of 2017, market participants are beginning to adopt longer-term perspectives. What specific attributes drive Bitcoin's popularity? Are cryptocurrencies simply "Internet Bubble 2.0"? If so, how might this chapter conclude? Is blockchain technology fundamentally fraudulent? If not, what might it look like in 5-10 years?
These questions now attract attention beyond tech enthusiasts, with financial institutions conducting increasingly sophisticated research. Goldman Sachs recently published a comprehensive report titled "Top of Mind" that addresses these very questions through detailed analysis.
Understanding Cryptocurrency Fundamentals
Goldman's global research team views cryptocurrencies as blockchain technology's first major experiment—and a classic speculative bubble. Similar to the dot-com era, where many companies vanished and early search engines became obsolete, numerous existing cryptocurrencies may eventually become worthless, a risk the market currently underprices. Meanwhile, blockchain technology itself holds significant potential to transform sectors like the sharing economy over the next 5-10 years, though this will require technological advances, regulatory clarity, and time to mature.
Nobel laureate Robert J. Shiller, Sterling Professor of Economics at Yale University, previously described Bitcoin as an "interesting experiment." He noted, "Bitcoin is another very clever idea. I am impressed by the technology. But to me, it's another technology. I tend to think of Bitcoin as an interesting experiment. It is not a permanent feature of our lives. We are overemphasizing Bitcoin. We should expand our focus to blockchain, which has other applications."
The Mining Mechanism and Economic Impact
Bitcoin's creation emerged from a disruptive technological vision. Following the financial crisis, Satoshi Nakamoto's seminal paper "Bitcoin: A Peer-to-Peer Electronic Cash System" introduced a groundbreaking concept that sparked global interest and inspired countless other cryptocurrencies.
Bitcoin's original purpose aimed potentially at replacing fiat currency. Nakamoto wrote, "I’ve been working on a new electronic cash system that’s fully peer-to-peer, with no trusted third party. Key features include: preventing double-spending through a peer-to-peer network; no trusted third party; anonymous participants; new coins generated through proof-of-work; and the proof-of-work mechanism also preventing double-spending."
The process known as "mining" involves Bitcoin's system issuing its own digital currency through competitive computational efforts. Every ten minutes, whichever miner successfully solves the cryptographic puzzle first receives a Bitcoin reward. This involves computers repeatedly calculating hash values through exhaustive enumeration. Profit motivation drives miners to seek faster mining methods, leading to various mining pools and nodes. This process relies on the Proof-of-Work (PoW) algorithm.
Jeff Currie, head of Goldman Sachs Global Commodities Research, highlights that Bitcoin mining isn't labor-intensive. For example, China's largest mining operation controls nearly 4% of the network's computing power, generating approximately $400 million in gross profit equivalent to 657,000 Bitcoins, yet employs only 50 people. In contrast, Canada produces about 5% of global oil output with nearly $100 billion annual gross profit but employs 57,000 people. This illustrates that unit oil production requires four times more human effort than Bitcoin mining. However, Bitcoin mining consumes substantially more energy. Research indicates that global Bitcoin mining electricity consumption this year exceeded the annual electricity use of 159 countries.
Storage and Accessibility Advantages
Bitcoin offers significant storage advantages. Currie notes that even obsolete 3.5-inch floppy disks could store nearly 30,000 private keys while representing substantial value.
Bitcoin ownership is established through private keys and addresses, similar to bank account passwords and account numbers. Typically, private keys are stored within Bitcoin wallet applications managed by wallet software. Creating a Bitcoin address doesn't require identity verification like opening a bank account; simply downloading a Bitcoin wallet generates an address. Receiving Bitcoin only requires sharing your wallet address.
Goldman also observes that cryptocurrencies gain popularity in countries with unstable currencies and capital controls. According to Google Trends, Nigeria, South Africa, and Ghana showed the highest Bitcoin search frequency over the past five years—all nations experiencing significant currency instability and foreign exchange restrictions.
The Speculative Bubble Narrative
Despite Bitcoin's unique advantages, Goldman Sachs maintains that speculative bubbles inevitably burst.
Limitations as Currency Replacement
Bitcoin replacing fiat currency appears increasingly unlikely. First, without central bank backing, Bitcoin cannot effectively hedge inflation or maintain price stability because its supply cannot adapt to demand changes—a key reason the gold standard was abandoned. Additionally, Bitcoin's extreme volatility and rising transaction fees diminish its utility as currency.
Many cryptocurrency enthusiasts embrace a persistent belief: the internet's development involved massive speculation and泡沫, without which today's technological advancements wouldn't exist. Some argue that first-mover advantage and brand效应 protect early tokens like Bitcoin, ensuring long-term survival and value appreciation.
Goldman challenges this perspective. Steve Strongin, head of Goldman Sachs Global Investment Research, offers compelling counterarguments: "The concept of first-mover advantage seems somewhat outdated across industries. In reality, examples of sustained first-mover advantage are rare. Early internet browsers and search engines didn't survive long-term. In cryptocurrencies, extreme price volatility affects nearly all tokens, not just Bitcoin, indicating the market itself struggles to identify eventual winners."
Strongin warns investors that current狂热 attitudes resemble assumptions that all cryptocurrencies will survive or retain value. "However, the high positive correlation among different cryptocurrencies concerns me. Unlike rational markets, new token issuance doesn't appear to diminish older tokens' value—they all behave like the same asset class. If this becomes a 'winner-takes-all' scenario, investors must account for future value deterioration in failing tokens. Given lacking intrinsic value, non-viable tokens could eventually trade at zero."
This represents a critical difference between cryptocurrencies and fiat currency. "When governments retire currencies, they typically recognize residual value and exchange it for new fiat," Strongin notes.
He further explains, "Cryptocurrencies also differ from securities. Stocks connect to earnings growth, but cryptocurrency values seem based on imagined future returns—the very definition of a bubble."
"Even those believing blockchain technology could change the world struggle to explain why cryptocurrencies experience violent price swings, including recent halvings. This volatility itself signifies speculative behavior," he adds.
Goldman suggests this era may resemble the dot-com bubble burst, where only a few surviving companies created substantial value. Amazon and Google survived that period, but today's Amazon barely resembles its early self, and besides Google, most early search engines failed to create lasting value and disappeared.
The critical question remains: Do today's cryptocurrencies include companies like early Amazon or Google, or will they become forgotten failures? Goldman believes most cryptocurrencies will likely never return to their previous value peaks.

Blockchain's Long-Term Value Proposition
Despite 2017's cryptocurrency bubble inflating to extreme levels—even blockchain concept stocks experienced speculative mania, with numerous companies exploiting the trend to boost share prices—Goldman believes blockchain technology remains genuinely transformative.
Transparency, Security, and Efficiency
Blockchain's transparency, security, and efficiency could make it an excellent choice for reshaping business environments. Goldman identifies three primary areas or scenarios where blockchain technology could find effective application.
1. The Sharing Economy
The sharing economy's essence involves陌生 parties efficiently sharing information or resources through peer-to-peer methods based on mutual trust to create mutual economic value. However, establishing trust between strangers remains challenging. Resource sharing transactions typically rely on centralized platforms like Airbnb, DiDi Chuxing, or Mobike that guarantee promise fulfillment. When centralized platforms encounter problems, shared trust crises emerge.
Goldman believes blockchain's decentralization, distributed centers, and autonomous mechanisms could complement sharing economy needs by opening peer-to-peer trust channels at individual levels.
2. Energy Sharing
Goldman identifies energy sharing as another promising application. Lawrence Orsini, founder of Brooklyn microgrid developer LO3, stated, "If you produce energy far away, you lose much value through transmission losses. But if you're right across the street, you use energy efficiently."
Practical implementation could involve localized energy microgrids where each household acts as either producer or consumer. Some homes with solar panels possess surplus electricity available for sale—simplified here as unit 1. Households needing electricity could purchase from those with sufficient surplus. Account private keys should generate through clients installed locally.
Industry insiders note blockchain's current security applications in energy internet include "secure identity authentication," "data security sharing," "peer-to-peer electricity market transaction settlement," and "smart asset transactions," aiming to enhance trust between people, things, and people-things within energy networks.
3. Financial Settlement Systems
Goldman also believes blockchain technology could streamline securities clearing and settlement processes, reducing errors and improving efficiency.
Goldman acknowledges that blockchain's early prototypes already exist. Limited market applications may develop within 1-3 years, expanding over 5-10 years. However, broader adoption could require over a decade, needing regulatory refinement and significant time for large-market rollout.
