Jeremy Grantham Says Bitcoin Will Quietly Fade, Questions Its Store‑of‑Value Case

Jeremy Grantham isn’t buying the Bitcoin narrative. On CNBC’s Squawk Box, the GMO co-founder dismissed crypto as purposeless speculation and predicted it will shrink over decades—more a slow fizzle than a dramatic collapse. His core critique was narrow and blunt: Bitcoin hasn’t behaved like a dependable store of value.

He pointed to the tape. Bitcoin, the largest cryptocurrency by market cap, is down about 52% from last October’s peak of $126,080 and has slipped 17% in the past month to roughly $60,529. Over the same window, he noted, gold printed a new high above $5,500 per ounce earlier this year before retracing more than 25% to around $4,096. For Grantham, that contrast underscores Bitcoin’s instability relative to a traditional value reservoir.

He also argued that people don’t rely on Bitcoin for serious commerce—no supermarket runs, no routine settlement—and claimed crypto primarily enables illicit money movement without a footprint. While he allowed that blockchain infrastructure might transform finance, he made clear his skepticism is aimed at Bitcoin and the broader crypto asset class, not the underlying rails. He’s not alone: Mark Cuban recently said Bitcoin underperformed when he expected a hedge, and he’s sold most of his holdings.

The point worth wrestling with is the store‑of‑value claim. Value storage isn’t just about appreciating price; it’s about reliability across time horizons and liquidity regimes. Bitcoin’s drawdowns can be severe, and in liquidity-tightening environments, it often trades like a high‑beta macro asset rather than “digital gold.” If your horizon is months, that volatility can invalidate its hedging role. If your horizon is cycles—spanning halvings and credit regimes—the distribution looks different, but the path dependency is psychologically punishing. Many allocators underestimate how reflexivity amplifies both the upside during easing and the downside when policy tightens.

Business reality matters too. A credible store of value requires deep, predictable demand and clear use cases beyond narrative. Bitcoin’s payment utility remains limited by throughput, user experience, and tax frictions, even as Lightning and custody improve. That gap keeps spot demand more momentum‑driven than utility‑anchored, which sustains volatility. Institutions that treat Bitcoin as a strategic reserve often size it accordingly—small enough to survive 50% drawdowns—suggesting the market implicitly accepts its instability today.

On the “criminals without a trace” claim, the picture is more nuanced. Public blockchains are transparent by default; chain analytics firms routinely help law enforcement trace flows, and high‑profile seizures support that. Yes, obfuscation tools exist and can complicate tracking, but the idea that crypto leaves no trail ignores the forensic reality many agencies now leverage. The ethical question is whether financial privacy tools are inherently suspect or simply dual‑use technologies—an old debate that predates crypto.

Where Grantham is directionally right is that trust is earned through consistent behavior. If Bitcoin wants the store‑of‑value mantle in mainstream portfolios, it has to demonstrate robustness across multiple macro cycles, not just in liquidity booms. That likely means continued maturation: clearer regulation, broader distribution via ETFs and retirement channels, better risk tooling, and steadier demand from corporate treasuries and sovereign actors. Rails innovation can help—faster settlement, improved custody, and interoperable payment layers—but those are necessary, not sufficient, for the asset to be treated like a reliable hedge.

Grantham’s forecast of a quiet fade reflects an understandable skepticism when judged by near‑term stability and everyday utility. The counterview rests on longer horizons, programmatic scarcity, and steadily professionalizing market structure. Which lens dominates will be decided less by slogans and more by how Bitcoin behaves through the next few policy cycles—and whether real‑world adoption can anchor demand enough to tame the reflexivity that still defines it.
