The notion that Bitcoin has firmly established itself as “digital gold” is now facing a fresh wave of scrutiny on Wall Street. This latest point of contention has less to do with the usual daily price swings and everything to do with the distant, yet rapidly approaching, future of computing. At the heart of this discussion are two influential strategists, both named Wood, who are presenting starkly different paths for global investors considering the world’s largest cryptocurrency. This significant divergence highlights a pivotal shift in how institutional capital is evaluating crypto assets in 2026. The debate has moved beyond mere speculation versus store of value, evolving into a more intricate calculation involving survivability, governance, and the specific kind of hedge investors believe they are acquiring.
The Quantum Exit: A Shift Towards Traditional Assets
Christopher Wood, the global head of equity strategy at Jefferies, has built a solid reputation for accurately gauging market sentiment, notably through his insightful “Greed & Fear” newsletter. His recent decision, however, runs counter to the institutional accumulation trend of the past two years: he has completely removed a 10% Bitcoin allocation from his model portfolio. This reallocation saw Jefferies pivot the Bitcoin sleeve into assets with much older, more established narratives: 5% into physical gold and another 5% into gold-mining stocks.
The rationale behind Wood’s move is rooted in managing extreme tail risk, rather than reacting to immediate market dynamics. He argued that advancements in quantum computing could eventually undermine the fundamental cryptography that secures the Bitcoin network. While many investors still categorize quantum threats as far-off “science projects,” Jefferies is treating this possibility as a disqualifying factor for long-horizon capital, such as pension funds.
This anxiety is finding validation among technical experts who suggest the timeline for such a threat is shrinking faster than markets might realize. Charles Edwards, founder of Capriole, for instance, has asserted that a quantum computer could potentially compromise Bitcoin in just 2 to 9 years without a significant upgrade, with a high probability falling within the 4 to 5-year window. Edwards describes the market as having entered a “Quantum Event Horizon,” a critical threshold where the risk of a quantum hack becomes roughly equivalent to the time needed to achieve consensus for an upgrade and execute its rollout.
From Jefferies’ perspective, the uncomfortable truth is that a powerful quantum computer could someday crack Bitcoin’s security, because its foundational cryptographic assumptions are vulnerable to these advanced future machines. The specific concern involves adversaries “harvesting” exposed public keys now, storing them, and decrypting their corresponding private keys later, once quantum hardware matures. Estimates indicate that over 4 million BTC are held in vulnerable addresses due to key reuse or older cryptographic formats. This creates a “harvest now, decrypt later” attack vector that could compromise a substantial portion of Bitcoin’s total supply.
Is the Quantum Threat Immediate? A Reality Check
However, not everyone agrees on the urgency of the quantum threat. Grayscale, one of the largest digital-asset managers, has sought to temper the 2026 market conversation by labeling quantum vulnerability a “red herring” for the current year. Their analysis suggests that while the threat is undoubtedly real, it is unlikely to be a significant price driver in the immediate future. Grayscale argues that, in the longer run, most blockchains and indeed much of the broader economy will require post-quantum upgrades anyway, aligning with ongoing developments within the crypto sector.
Andre Dragosch, Head of Research at Bitwise Europe, has also pushed back against the “immediate doom” narrative. He emphasizes the immense computational gap between current technology and what would be required for a viable quantum attack. While Dragosch acknowledges concerns about older wallets, he maintains that the Bitcoin network itself remains extraordinarily robust.
“Bitcoin now runs at 1 zeta hash per second, equivalent to more than one million El Capitan-class supercomputers. That’s orders of magnitude beyond the reach of today’s quantum machines and even beyond those expected in the foreseeable future.”
This perspective suggests that the sheer scale of Bitcoin’s computational power provides a significant buffer against nascent quantum capabilities.
Cathie Wood's Uncorrelated Case for Bitcoin
Amidst this debate, ARK Invest is steadfastly reinforcing its argument that Bitcoin deserves a place in modern investment portfolios precisely because it exhibits behavior unlike any other asset class. In their 2026 outlook note, ARK’s Cathie Wood leaned heavily on correlation data rather than ideological conviction. Her argument is pragmatic: Bitcoin’s return stream has maintained a weak link to major asset classes since 2020, thereby offering a valuable tool for improving overall portfolio efficiency.
ARK supported this view with a compelling correlation matrix, analyzing weekly returns from January 2020 through January 2026. The data revealed that Bitcoin’s correlation with gold stood at a mere 0.14, and with bonds, it was an even lower 0.06. Perhaps most strikingly, the analysis showed that the S&P 500’s correlation with bonds was actually higher than Bitcoin’s correlation with gold.
Wood leverages this data to assert that Bitcoin should be viewed as a valuable diversifier for asset allocators seeking higher returns per unit of risk in the years ahead. This represents a subtle but crucial evolution in ARK’s messaging. They are reframing Bitcoin not merely as a “newer version of gold,” but as an “uncorrelated return stream with asymmetric upside.”
Redefining the Hedge: Adaptability vs. Immutability
For investors observing the split between two of Wall Street’s high-profile strategists, the immediate takeaway is not that Bitcoin is inherently flawed. Rather, it signifies that the institutional narrative surrounding the asset is maturing into something far more discerning and demanding. Jefferies, in essence, is stating that a hedge which might eventually necessitate a contentious protocol-level migration is fundamentally different from a physical asset like gold, even if both can appreciate during similar macroeconomic conditions.
The core distinction here is that gold does not require active coordination, software upgrades, or complex governance mechanisms to maintain its validity as an asset. Bitcoin, on the other hand, is a hedge whose long-term viability ultimately depends on its ability to adapt and evolve. Conversely, there is a strong counterargument that traditional finance faces more immediate peril from quantum computing than Bitcoin does. As Dragosch pointed out:
“Banks depend heavily on long-lived RSA/ECC keys across authentication and interbank communications. Once quantum machines can break these, systemic attacks become possible, far earlier than any realistic threat to Bitcoin’s decentralized architecture.”
With these considerations in mind, ARK Invest is effectively arguing that the substantial benefits of portfolio diversification can justify a Bitcoin position, even if the asset is still in an evolutionary stage. Thus, the pivotal question that looms over these contrasting cases is whether Bitcoin can credibly coordinate a post-quantum transition without fracturing the vital social consensus that underpins its monetary value.
