Economist Steve Keen, known for calling the 2008 Financial Crisis, has renewed his long-standing skepticism toward Bitcoin, warning that the cryptocurrency could eventually lose all value.

Speaking on The Diary Of A CEO podcast, Keen argued that a combination of structural weaknesses, energy constraints, and geopolitical risks has undermined Bitcoin’s long-term viability. Notably, his latest remarks build on years of criticism of the economic foundations of digital assets.

Key Points

• Steve Keen argues Bitcoin’s energy-intensive design threatens its long-term viability amid global climate pressures.
• He highlights geopolitical risks, such as energy disruptions from international conflicts, as a potential threat to Bitcoin’s network.
• Keen warns Bitcoin’s fixed supply could trigger deflation, reducing spending and economic activity.
• He questions Bitcoin’s ability to function as practical money, calling it primarily a speculative asset.
• Bitcoin’s price moves with risky assets, undermining its ‘digital gold’ narrative and its claims of stability.

Structural Weaknesses and Energy Constraints

At the core of Keen’s argument is the belief that Bitcoin’s design may not be sustainable over time. Specifically, he pointed to the network’s heavy reliance on energy-intensive computing, which underpins its security but comes at a high cost.

According to Keen, growing global pressure to reduce energy consumption could put cryptocurrencies in the regulatory spotlight. As governments confront climate and resource challenges, high-energy systems like Bitcoin may face increasing restrictions.

In this context, environmental concerns could directly shape policy decisions affecting crypto.

Geopolitical Risks Add Pressure

Beyond environmental issues, Keen emphasized the role of geopolitical instability in amplifying Bitcoin’s vulnerabilities. For instance, he cited tensions involving Iran as an example of how global crises could disrupt energy supplies.

In such scenarios, governments would likely prioritize essential services like food production and heating. Consequently, energy-intensive networks such as Bitcoin could be sidelined or even shut down, accelerating the risks already associated with its high energy dependence.

A Currency or a Speculative Asset?

Moreover, Keen questioned Bitcoin’s ability to function as money. In his view, it exists in a gray area between a speculative investment and a practical currency.

To illustrate this point, he referenced Gresham’s Law, which suggests that people tend to hoard assets expected to rise in value rather than spend them. Therefore, this behavior, he said, limits Bitcoin’s usefulness as a medium of exchange and undermines its original purpose.

Deflationary Pressures from Fixed Supply

Another key concern lies in Bitcoin’s fixed supply model. Keen warned that such a system could create persistent deflationary pressure, discouraging spending and investment.

While inflation presents its own challenges, he argued that deflation can be more damaging over time. In particular, it increases the real burden of debt and can slow economic activity—factors that, in turn, could weaken any system built around a fixed-supply currency.

A Crowded Market Facing Consolidation

Looking beyond Bitcoin itself, Keen compared the broader crypto ecosystem’s rapid expansion to the Cambrian Explosion, a period marked by a sudden surge in diversity.

With more than 20,000 tokens in existence, he believes the market is likely to undergo a sharp contraction. In fact, many projects, in his view, lack the trust and institutional backing needed to survive, suggesting that only a small number of assets may endure.

Market Behavior Challenges “Digital Gold” Narrative

Additionally, Keen pushed back against Bitcoin’s reputation as a stable store of value. He observed that its price often moves in tandem with risk-sensitive assets like technology stocks.

This correlation, therefore, contradicts the idea of Bitcoin as “digital gold”. Instead, it behaves more like a speculative asset driven by broader market sentiment, thus further blurring its identity.

BTC “Greater Fool” Dynamic Drives Valuation

Finally, Keen attributed much of Bitcoin’s valuation to investor expectations rather than intrinsic utility. He linked this to the Greater Fool Theory, where buyers purchase assets in the hope of selling them at higher prices later.

Such dynamics, he suggested, raise concerns about long-term sustainability—particularly if market sentiment shifts.

A Cautious Outlook

Taken together, Keen’s analysis presents a cautious view of Bitcoin and the wider crypto market. Overall, he connects energy concerns, economic structure, and geopolitical risks into a single narrative.

While his perspective remains open to debate, it contributes to ongoing discussions about the durability of digital assets in a changing global environment.
