One Of Wall Street’s Top Strategists No Longer Trusts Bitcoin

What Happened

In his view, quantum computing weakens the argument that Bitcoin can function as a dependable, multi-decade store of value, particularly for pension-style, long-term investors.

Recent analysis from Coinbase has echoed some of those concerns. Coinbase Head of Investment Research David Duong said quantum computing poses long-term risks beyond private key security, potentially affecting Bitcoin’s economic and security models.

Market Context

Grab a coffee — because this isn’t about price charts, ETF flows, or the next halving narrative. It’s about something far more uncomfortable: whether Bitcoin, as it exists today, is built to last.

A quiet but consequential shift is unfolding in institutional crypto thinking. Christopher Wood, global head of equity strategy at Jefferies and one of Wall Street’s most closely followed market strategists, has removed Bitcoin entirely from his flagship model portfolio.

The Jeffries executive did not cite price volatility but instead cited doubts about the asset’s long-term durability.

“The once-distant threat of quantum computing has prompted one of the most closely followed market strategists to walk away from Bitcoin,” Bloomberg reported, citing Wood in the newsletter and highlighting how a theoretical risk is now entering mainstream portfolio construction.

The debate exposes a widening divide between capital allocators and developers. Nic Carter, a partner at Castle Island Ventures, captured this tension in a December post.

Why It Matters

“There is growing concern in the Bitcoin community that quantum computing could only be a few years away rather than a decade or more,” Wood wrote.

However, cryptographically relevant quantum computers (CRQCs) could collapse that asymmetry. This could allow attackers to reverse-engineer private keys in hours or days.

Quantum Risk, Governance, and the Institutional Rethink of Bitcoin

Jefferies noted that while Bitcoin has undergone forks before, confiscating or invalidating coins could undermine the very principles that give the network credibility.

Jefferies also highlighted that large portion of the Bitcoin supply could be vulnerable in a quantum scenario. These include:

Wood has cut a 10% Bitcoin allocation from Jefferies’ model portfolio and reallocated it evenly to physical gold and gold-mining stocks.

The decision was outlined in the latest edition of his Greed & Fear newsletter, where Wood pointed to the long-term threat posed by advances in quantum computing to Bitcoin’s security and store-of-value thesis.

Wood was an early institutional supporter of Bitcoin, first adding the asset to his model portfolio in December 2020 amid pandemic-era stimulus and fears of currency debasement.

He later raised the exposure to 10% in 2021. Notably, Bitcoin has since surged by approximately 325% since the initial allocation compared with gold’s 145% gain. Notwithstanding, Wood says performance is no longer the point.

Indeed, Bitcoin’s security rests on cryptographic systems that make it practically impossible for today’s computers to derive private keys from public ones.

Nevertheless, governance is at the heart of the issue. Proposed solutions, including burning quantum-vulnerable coins or forcing a migration to post-quantum cryptography, raise uncomfortable questions about property rights and rule changes.
