Bitcoin has surged past the $100,000 milestone, transforming from a fringe digital experiment into a $2 trillion asset class and catalyzing the global crypto market toward a $4 trillion valuation. Yet, despite its meteoric rise, opinions among financial elites remain deeply divided. While some once dismissed Bitcoin as a fleeting fad or outright fraud, others have revised their views in light of its resilience and adoption.
This article explores how five prominent financial figures — once skeptical or even hostile toward Bitcoin — are now navigating its growing influence in the world of finance.
👉 Discover how leading financial minds are redefining value in the digital age.
Jamie Dimon – From “Fraud” to “Pet Rock”
Jamie Dimon, CEO of JPMorgan Chase, has long been one of Bitcoin’s most vocal critics. In 2017, he famously called it a “fraud” and threatened to fire any employee caught trading it. He later referred to Bitcoin as a “decentralized Ponzi scheme” and urged regulators to shut it down entirely.
Despite JPMorgan’s pioneering work in blockchain technology and its investment in Bitcoin ETFs, Dimon has maintained a personal stance of skepticism. As recently as 2025, he likened Bitcoin to a “pet rock” — an asset with no intrinsic utility or productive value.
However, his firm’s actions suggest a more nuanced institutional embrace of crypto infrastructure, even if Dimon himself remains unconvinced of its long-term merit.
Warren Buffett – The Relentless Critic
Warren Buffett, the legendary investor and CEO of Berkshire Hathaway, has consistently expressed disdain for cryptocurrencies. His most scathing remark came in 2018 when he described Bitcoin as “rat poison squared” — a toxic derivative with no underlying value.
Buffett argues that unlike stocks or real estate, Bitcoin produces nothing. In a 2023 CNBC interview, he reiterated his stance, attributing the crypto craze to Americans’ gambling instincts rather than sound investment principles.
Even at the 2025 Berkshire shareholder meeting, Buffett avoided discussing Bitcoin directly — but his silence speaks volumes. For him, true value lies in businesses that generate cash flow, not in speculative digital tokens.
Yet, despite his public skepticism, some analysts note that Buffett’s longtime partner, Charlie Munger, previously acknowledged Bitcoin’s role in challenging traditional financial systems — a subtle crack in the armor of outright rejection.
Larry Fink – From Skeptic to Strategic Advocate
Larry Fink, CEO of BlackRock, once labeled Bitcoin the “money laundering index” and dismissed it as something his clients didn’t want. But over time, his perspective shifted dramatically.
After conducting deep research into digital assets, Fink reversed course. Today, BlackRock manages the world’s largest Bitcoin ETF, and Fink now describes Bitcoin as a legitimate asset class — one that offers returns uncorrelated with traditional markets.
He emphasizes Bitcoin’s potential as a hedge against currency devaluation and geopolitical instability. In his view, institutional adoption is not just inevitable but necessary in a world of rising inflation and monetary uncertainty.
Fink’s evolution reflects a broader trend: even former critics are recognizing Bitcoin’s role in diversified portfolios.

Ken Griffin – Admits He Was Wrong, But Still Hesitant
Ken Griffin, founder of Citadel, once compared Bitcoin to the 17th-century tulip mania — a classic example of irrational exuberance. In 2021, during Bitcoin’s price surge, he went further, calling it a “jihad against the dollar.”
But by 2025, Griffin admitted his earlier judgment was “wrong.” Citadel now actively trades cryptocurrencies and offers crypto derivatives to clients.
Still, Griffin questions Bitcoin’s economic utility. He sees it primarily as a speculative store of value rather than a functional currency or technological breakthrough.
His position illustrates a growing divide: even those who acknowledge Bitcoin’s market presence may not fully endorse its foundational promise.
Ray Dalio – From Bubble to Digital Gold
Ray Dalio, co-founder of Bridgewater Associates, initially dismissed Bitcoin in 2017 as a “speculative bubble.” But over the years, his tone has softened significantly.
By 2021, he praised Bitcoin as a “remarkable invention” and likened it to gold — a non-sovereign store of value. Dalio revealed he owns both Bitcoin and Ethereum and believes digital assets play a crucial role in hedging against fiat currency depreciation.
However, he remains cautious about government backlash. “If Bitcoin succeeds,” he warned, “governments will try to kill it — and they have the power to do so.” He fears regulatory crackdowns could stifle adoption despite Bitcoin’s long-term potential.
Recently, Dalio has urged investors to consider both gold and Bitcoin as safeguards amid rising global debt levels and central bank instability.
Frequently Asked Questions (FAQ)
Q: Why did so many financial leaders initially reject Bitcoin?
A: Early skepticism stemmed from Bitcoin’s lack of intrinsic value, volatility, association with illicit activity, and absence of regulatory oversight. Many traditional financiers viewed it as a speculative bubble rather than a legitimate asset.
Q: Has institutional adoption changed expert opinions on Bitcoin?
A: Yes. The launch of Bitcoin ETFs, custody solutions, and blockchain integration by major banks have forced even critics to reconsider. Institutional involvement lends credibility and signals long-term viability.
Q: Is Bitcoin truly “digital gold”?
A: Proponents argue yes — like gold, Bitcoin is scarce and decentralized. Critics counter that gold has industrial uses and centuries of trust behind it, while Bitcoin’s value remains largely speculative.
Q: Can governments ban Bitcoin?
A: While governments can restrict or regulate exchanges and usage within their borders, completely eliminating a decentralized network like Bitcoin is extremely difficult due to its global and distributed nature.
Q: Should I invest in Bitcoin based on expert opinions?
A: Expert views are divided. Some see it as essential portfolio diversification; others warn of high risk. Always conduct independent research and assess your risk tolerance before investing.
Q: What drives Bitcoin’s price today?
A: Key factors include macroeconomic trends (inflation, interest rates), institutional adoption, regulatory news, supply constraints (halving events), and market sentiment.
