Bitcoin has emerged as one of the most polarizing and widely discussed financial assets of the 21st century. Since entering the mainstream spotlight in 2021, its meteoric rise — briefly surpassing $58,000 per coin and outpacing the value of one kilogram of gold — has sparked intense debate among investors, institutions, and academics alike. While its market capitalization has crossed the trillion-dollar threshold, questions about its legitimacy, sustainability, and long-term role in finance remain unresolved.
To better understand Bitcoin’s complex nature, we turn to expert insights from the University of Maryland’s Robert H. Smith School of Business. David Kass, a clinical professor of finance; Brent Goldfarb, academic director of the Dingman Center for Entrepreneurship; and Samuel Handwerger, a lecturer in accounting, offer a balanced, research-informed perspective on Bitcoin’s evolution, value proposition, environmental impact, and regulatory challenges.
Bitcoin as a Digital Asset
At its core, Bitcoin is a digital asset — but unlike traditional investments such as stocks or commodities, it lacks conventional fundamentals like earnings, dividends, or industrial utility.
“Bitcoin is not like a stock or bond,” explains Professor David Kass. “It doesn’t generate cash flow. There’s no balance sheet, no income statement. We can’t apply discounted cash flow models to determine its intrinsic value. What makes Bitcoin ‘worth’ $10,000 or $50,000? Ultimately, it comes down to supply and demand.”
This absence of fundamental valuation metrics places Bitcoin in a unique category. Its price movements are driven largely by market sentiment, speculation, and macroeconomic narratives rather than performance-based analysis.
Supporters often compare Bitcoin to digital gold — a decentralized store of value with a fixed supply cap of 21 million coins. This scarcity, they argue, mirrors the finite nature of physical gold and protects against inflation and currency devaluation.
However, Professor Brent Goldfarb cautions against this analogy:
“Gold has real-world applications — in jewelry, electronics, aerospace. Bitcoin doesn’t. Its value stems from collective belief, not utility. And while both are scarce, gold has proven stability over centuries. Bitcoin’s volatility disqualifies it as a reliable store of value — at least for now.”

Is Bitcoin an Investment or a Speculation?
One of the central debates revolves around whether investing in Bitcoin constitutes true investing or mere speculation.
Traditional assets derive value from predictable income streams:
- Stocks pay dividends and reflect company earnings.
- Bonds offer interest payments.
- Real estate generates rental income.
Bitcoin produces none of these. Instead, its value hinges entirely on the expectation that someone else will pay more for it in the future — a concept known as the Greater Fool Theory.
“People buy Bitcoin not because of what it does today,” says Kass, “but because they believe others will pay more tomorrow. That’s speculation, not investment.”
This dynamic fuels extreme price swings. A single tweet or corporate announcement can trigger double-digit percentage moves within hours. Such volatility makes Bitcoin unsuitable as a medium of exchange or stable store of value — two key functions of money.
Goldfarb adds:
“Theoretically, Bitcoin has no price ceiling. But without an anchor — no cash flows, no earnings — it also has no floor. The bottom could be zero.”
The "Digital Tulip" Debate
Critics frequently label Bitcoin a modern-day tulip mania, referencing the 1637 Dutch bubble where tulip bulb prices soared before collapsing by over 99%. At the height of the frenzy, some bulbs were priced higher than a skilled artisan’s annual salary.
“Bitcoin shares similarities with tulips,” Goldfarb notes. “Both derive value from perception and scarcity. Both attract speculative fever. The key difference? Tulips at least had aesthetic appeal.”
Yet supporters counter that Bitcoin is more than just hype — it’s built on blockchain technology, offers decentralized control, and enables borderless transactions without reliance on banks or governments.
Still, without widespread adoption as a transactional currency and under unclear regulatory frameworks globally, its long-term viability remains uncertain.
Environmental Impact and Energy Consumption
Bitcoin’s environmental footprint has drawn increasing scrutiny. The process of mining — validating transactions and securing the network — requires massive computational power and electricity.
“Global Bitcoin mining consumes around 78 terawatt-hours (TWh) annually,” says Goldfarb. “That’s comparable to Chile’s entire electricity usage for a nation of 20 million people.”
Each Bitcoin transaction uses energy equivalent to over 436,000 Visa transactions. This raises serious concerns about sustainability, especially as climate change becomes a top global priority.
Elon Musk’s reversal on Tesla accepting Bitcoin in 2021 highlighted this tension: while praising Bitcoin’s innovation, he cited environmental costs as grounds for halting cryptocurrency payments.
“You can’t champion green energy with electric cars and then fund operations through an energy-intensive blockchain,” Goldfarb observes.
Efforts to transition mining toward renewable energy sources are underway, but scalability and transparency remain challenges.

Regulatory Landscape and Tax Implications
Despite growing institutional interest — including investments by Tesla, MassMutual, and BlackRock — regulators remain cautious.
In the U.S., the IRS treats cryptocurrency as property, not currency. This means every transaction carries potential tax consequences.
Samuel Handwerger emphasizes:
“If you buy Bitcoin for $200 and spend it on a $400 laptop, you’ve realized a $200 capital gain — just as if you sold it. That gain is taxable.”
Even receiving crypto as payment for goods or services triggers income reporting requirements. Employers paying wages in Bitcoin must report the fair market value at time of payment.
The IRS has taken enforcement seriously:
- In recent years, it sent over 10,000 letters to Coinbase users reminding them of reporting obligations.
- It classifies unreported crypto activity as tax evasion — punishable by penalties or legal action.
“Crypto may feel virtual,” Handwerger says, “but to the IRS, it’s very real.”
Globally, regulatory approaches vary:
- China bans crypto trading and mining.
- The EU advances MiCA regulations to standardize oversight.
- The U.S. continues piecemeal enforcement across SEC, CFTC, and IRS jurisdictions.
Clearer rules could boost legitimacy — or stifle innovation depending on their design.
Frequently Asked Questions (FAQ)
Q: Can Bitcoin replace traditional money?
A: Not currently. High volatility, slow transaction speeds, and scalability issues prevent Bitcoin from functioning as everyday currency. It’s better viewed as a speculative asset or potential long-term store of value.
Q: Is Bitcoin truly decentralized?
A: In theory, yes — no single entity controls the network. In practice, mining power is concentrated among a few large pools, mostly located in regions with cheap electricity, raising centralization concerns.
Q: How does halving affect Bitcoin’s price?
A: Approximately every four years, the reward for mining new blocks is cut in half (“halving”), reducing new supply. Historically, halvings have preceded bull markets due to increased scarcity expectations — though past performance doesn’t guarantee future results.
Q: Should I invest in Bitcoin?
A: Only after thorough research and risk assessment. Due to extreme volatility, most financial advisors recommend allocating only a small portion of a diversified portfolio to crypto — if any.
Q: What happens when all 21 million Bitcoins are mined?
A: Mining rewards will shift entirely to transaction fees. Whether this model sustains network security remains an open question for future economists and developers.
Q: Is Bitcoin illegal?
A: No — not in most countries. However, regulations vary widely. Always check local laws before buying or using cryptocurrency.
Final Thoughts: Innovation vs. Speculation
Bitcoin represents a groundbreaking technological achievement — a decentralized digital ledger secured by cryptography and maintained by global consensus. Yet its financial role remains ambiguous.
For believers, it’s digital gold, financial sovereignty, and a hedge against inflation. For skeptics, it’s speculative mania, an environmental burden, and a regulatory time bomb.
As Professor Goldfarb puts it:
“Bitcoin combines elements of innovation and illusion. The technology behind it may endure — even transform finance. But whether this particular asset retains value over decades remains to be seen.”
Investors should approach Bitcoin with eyes wide open — respecting its potential while acknowledging its risks.
