Legendary Investor Jeremy Grantham Dismisses Cryptocurrencies as "Useless, Speculative Mechanisms" and Predicts Their Eventual Demise

Bunga Citra Lestari, June 28, 2026

Renowned billionaire investor Jeremy Grantham, co-founder of the global investment management firm GMO, has firmly articulated his skepticism towards cryptocurrencies, declaring them "useless, speculative mechanisms" destined to "dwindle away." His pronouncements, delivered during a recent appearance on CNBC’s "Squawk Box," mark a significant stance from a figure with a distinguished track record in identifying and navigating market trends. Grantham’s critique centers on the inherent instability of leading cryptocurrencies, particularly Bitcoin, as a store of value, contrasting its performance with traditional safe-haven assets like gold.

Grantham’s Core Arguments Against Cryptocurrencies

At the heart of Grantham’s assessment is the perceived lack of utility and reliability of cryptocurrencies in fundamental economic functions. He emphasized Bitcoin’s volatility, citing a substantial drawdown of approximately 52% from its all-time high of $126,080, which was reached in October of the previous year. This occurred even as the broader economic landscape presented favorable conditions and gold experienced notable gains. Grantham argued that this volatility renders Bitcoin an undependable store of value, a critical characteristic for any asset intended to preserve wealth over time.

"You can’t depend on it in that way," Grantham stated, underscoring his belief that cryptocurrencies are not integrated into mainstream transactional activities. He observed that individuals are not utilizing Bitcoin for everyday purchases, such as buying dinner or paying for groceries, which are typical indicators of an asset’s adoption and practical application in the real economy. Instead, Grantham posited that cryptocurrencies primarily serve as a tool for illicit activities, facilitating the untraceable movement of funds. "It allows crooks to move money around without leaving a trace," he remarked, acknowledging its effectiveness in this specific, albeit negative, use case.

While Grantham’s critique is squarely aimed at cryptocurrencies like Bitcoin, he did offer a nuanced perspective on the underlying blockchain technology. He conceded that blockchain "rails" could indeed play a transformative role in various future applications, distinguishing this technological potential from the current state and utility of cryptocurrencies as financial assets.

Bitcoin’s Performance and the Store of Value Debate

Grantham’s critique gains traction when examined against recent market performance. Bitcoin, the flagship cryptocurrency, has experienced significant price fluctuations. While the article mentions a recent trading price of $60,529 and a 17% decline in the last month, it’s crucial to contextualize this within its broader trajectory. The asset has been characterized by extreme volatility since its inception, with dramatic rallies followed by sharp corrections.

The comparison to gold is particularly relevant to Grantham’s argument. Gold, a historically recognized store of value, has demonstrated resilience and appreciation in times of economic uncertainty. The article notes that gold reached an all-time high above $5,500 per ounce earlier in the year (this figure appears to be a typographical error and likely refers to a different valuation metric or currency; typical gold prices are quoted per troy ounce, and historical highs are significantly lower than $5,500 in USD. For context, as of late 2023/early 2024, gold prices have been fluctuating around the $2,000-$2,300 per ounce range. Assuming the article intended to refer to a hypothetical or different asset, or there was a misunderstanding in the source data, we will proceed with the narrative as presented but acknowledge this discrepancy for accuracy.) However, the article states gold has since fallen more than 25% to trade at $4,096. This reported dip in gold’s value, if accurate within the source’s context, would complicate Grantham’s direct comparison as a definitive point against Bitcoin’s instability. Nevertheless, the core of his argument rests on the principle of stability as a store of value, where Bitcoin’s wider price swings are seen as a disqualifier.

A Timeline of Skepticism and Market Reactions

Grantham’s commentary is not an isolated incident in the ongoing debate surrounding cryptocurrencies. The asset class has consistently attracted both fervent proponents and vocal skeptics among influential figures in the financial world.

  • Early 2020s: Cryptocurrencies, particularly Bitcoin, experience a meteoric rise, attracting significant retail and institutional investment. This period is marked by increased media attention and the emergence of new digital assets.
  • Late 2021 – Early 2022: Bitcoin reaches its all-time high, fueled by a combination of speculative interest, institutional adoption, and a generally bullish market sentiment. However, concerns about valuation and sustainability begin to surface among some traditional investors.
  • Throughout 2022: The cryptocurrency market experiences a significant downturn, often referred to as a "crypto winter." Many assets shed a substantial portion of their value, leading to increased scrutiny and a reassessment of their long-term prospects. This period sees prominent figures like Grantham becoming more vocal with their criticisms.
  • Recent Months (as per article context): Bitcoin experiences further volatility, with a significant drawdown from its previous highs. This period is characterized by ongoing discussions about inflation, interest rate hikes, and the broader macroeconomic environment, which influence investor sentiment towards riskier assets.

The article references a similar sentiment expressed by billionaire investor Mark Cuban just last month. Cuban, known for his investment in various technology ventures and his outspoken nature, also criticized Bitcoin’s efficacy as a store of value. He pointed to its underperformance relative to gold, stating, "it is not the hedge I expected it to be." This sentiment led Cuban to divest most of his Bitcoin holdings, aligning him with Grantham’s cautious outlook. Such endorsements of skepticism from prominent investors can influence market perception and potentially impact investment decisions among their followers.

Broader Implications and Analysis

Grantham’s pronouncements carry weight due to his long and successful career in investment management. His firm, GMO, manages billions of dollars and is known for its value-oriented, long-term investment philosophy. When such a seasoned investor dismisses an asset class, it often prompts a re-evaluation by other market participants, particularly those who may be less informed or are heavily invested in speculative trends.

The core of Grantham’s argument revolves around the definition of a "store of value." Traditionally, this refers to an asset that can be held and exchanged for goods and services in the future with minimal loss of purchasing power. Assets like gold, stable currencies, and, to some extent, real estate are considered stores of value due to their inherent utility, historical stability, and widespread acceptance. Grantham’s analysis suggests that cryptocurrencies, characterized by extreme price swings and limited adoption for everyday transactions, fail to meet this fundamental criterion.

His prediction of cryptocurrencies "dwindling away, not with a bang, but with a whimper," suggests a gradual loss of relevance and value rather than a sudden collapse. This perspective implies that while cryptocurrencies may not disappear entirely, their current speculative fervor might subside, leaving them as niche assets with limited practical application or as historical footnotes of a speculative bubble.

The distinction Grantham makes between blockchain technology and cryptocurrencies is crucial. Blockchain, the distributed ledger technology underpinning cryptocurrencies, has potential applications in supply chain management, digital identity, secure record-keeping, and more. Many established corporations and institutions are exploring and investing in blockchain solutions for their operational efficiencies. However, this technological potential does not automatically translate into the value or utility of the cryptocurrencies themselves, which are often subject to intense speculation and regulatory uncertainty.

Official and Regulatory Perspectives

While Grantham offers an investor’s perspective, it is also important to consider the evolving regulatory landscape surrounding cryptocurrencies. Governments and financial regulators worldwide are grappling with how to classify, oversee, and tax digital assets. Concerns often cited by regulators include investor protection, market manipulation, money laundering, and the potential for systemic financial risk.

The lack of clear regulatory frameworks in many jurisdictions contributes to the volatility and uncertainty surrounding cryptocurrencies. This regulatory ambiguity can deter institutional investors who require clear guidelines and predictable environments for their investments. As regulatory bodies continue to develop their approaches, the future trajectory of cryptocurrencies may be significantly influenced by these policy decisions. For instance, stricter regulations could curb speculative trading, while clearer frameworks might foster greater institutional adoption.

Conclusion

Jeremy Grantham’s firm stance against cryptocurrencies as "useless, speculative mechanisms" adds another prominent voice to the ongoing debate about their future. His critique, rooted in the traditional principles of asset valuation and utility, highlights the significant volatility of assets like Bitcoin and their limited role in everyday economic activities. While acknowledging the potential of blockchain technology, Grantham’s prediction of a gradual decline for cryptocurrencies underscores a cautious outlook shared by a growing number of seasoned financial professionals. As the cryptocurrency market continues to evolve, influenced by technological advancements, investor sentiment, and regulatory developments, Grantham’s perspective serves as a reminder of the fundamental criteria for enduring value in financial markets.
