Harvard economist Kenneth Rogoff admits his 2018 forecast was wrong. What this reversal tells us about Bitcoin’s rise, Wall Street adoption, and the battle for legitimacy.
In 2018, Harvard economist Kenneth Rogoff predicted that Bitcoin would fall to $100. At the time, his skepticism aligned with a chorus of establishment voices dismissing the world’s first cryptocurrency. Warren Buffett famously called Bitcoin “rat poison squared”, while JPMorgan’s Jamie Dimon dismissed it outright as a “fraud”.
Fast forward to 2025: Bitcoin has surged more than 1,000% since Rogoff’s original forecast, recently breaking through $124,000. Faced with the undeniable reality, Rogoff has taken to X (formerly Twitter) to publicly acknowledge where he went wrong. His reversal is telling, not because he has become a Bitcoin bull (he hasn’t), but because his admission exposes how much has changed in the global financial landscape.
Rogoff’s Three Missteps
In his candid reflection, Rogoff admitted three crucial blind spots in his 2018 thesis:
- Overestimating Regulatory Rationality: Rogoff assumed the United States and other major economies would craft “sensible” regulation to curb crypto adoption. Instead, policymakers stumbled through inconsistent and reactive policies. The U.S. alone has oscillated between heavy-handed enforcement and tacit acceptance, culminating in the approval of spot Bitcoin ETFs in 2024. Regulation, far from being a deterrent, often accelerated mainstream legitimacy.
- Underestimating the Underground Economy: He overlooked Bitcoin’s entrenched role in the $20 trillion global shadow economy—a sphere encompassing everything from tax evasion and illicit trade to unbanked populations and informal markets. While critics see this as a liability, Bitcoin’s ability to thrive in opaque and politically unstable environments has been part of its resilience.
- Failing to Foresee Regulatory Capture: Perhaps most provocatively, Rogoff noted he did not anticipate that regulators themselves, including what he termed the “regulator-in-chief,” would personally hold large amounts of crypto. This point underscores the blurred lines between policymaking and self-interest. When those tasked with oversight have skin in the game, regulation is more likely to bend toward preservation than prohibition.
The Broader Pattern of Skepticism Turned Contrition
Rogoff’s walk-back echoes the grudging reassessments we have seen from other establishment titans. Buffett’s Berkshire Hathaway, while still cautious, has indirect exposure to Bitcoin through investments in companies like Nubank, a digital bank offering crypto services. JPMorgan, once led by Dimon’s fiery denunciations, is now a leading provider of blockchain-based financial services and a significant player in tokenized assets.
What unites these figures is not ideological conversion, but recognition of Bitcoin’s staying power. Each underestimated the network effect, technological resilience, and shifting public sentiment that have made Bitcoin not just a speculative asset but a fixture of the financial system.
Why This Matters: Narratives Drive Markets
The clash between Rogoff’s reversal and Bitcoin’s record-setting rally highlights a deeper truth: narratives shape markets as much as fundamentals. For years, the prevailing narrative was that Bitcoin was a bubble destined to pop. Today, the narrative is increasingly one of institutional adoption, geopolitical hedging, and digital scarcity. When BlackRock, Fidelity, and other Wall Street giants launched Bitcoin ETFs, they effectively cemented the asset as a legitimate portfolio component for both retail and institutional investors.
Narratives, however, remain fragile. Rogoff, despite conceding his errors, still cautions that Bitcoin’s long-term trajectory hinges on regulatory tolerance. A coordinated crackdown by major governments or, conversely, a regulatory green light for broader adoption in other jurisdictions could dramatically reshape its path. The story is not over; it is simply evolving.
The Bigger Picture: Legitimacy, Regulation, and Power
At its core, the Bitcoin debate is about legitimacy. Who gets to decide what qualifies as “money”? Central banks and regulators? Or decentralized networks and market consensus? Rogoff’s misjudgment illustrates how even elite economists can miss the shifting ground beneath them when technological and social momentum converge. His updated stance also reminds us that financial systems are not governed solely by rational models, but by politics, human incentives, and, yes, vested interests.
Looking Forward
Bitcoin, currently around $115,000, represents more than just price appreciation; it is a marker of a paradigm shift. What was once dismissed as a fringe experiment now sits at the intersection of finance, technology, and global governance. Critics may still scoff, but their skepticism increasingly reads less like analysis and more like resistance to change. But one fact is hard to ignore: those who dismissed it outright have repeatedly found themselves forced to recalibrate.
