Wall Street’s faith in Bitcoin is cracking under the quantum computing threat, as one of its top strategists pulls the plug on the asset entirely. Christopher Wood, global head of equity strategy at Jefferies, has axed a 10% Bitcoin allocation from his model portfolio, redirecting it to gold and gold miners. This isn’t knee-jerk volatility panic; it’s a calculated bet against Bitcoin’s long-term viability. Forget the price pumps and ETF hype—this move signals deeper institutional unease about Bitcoin’s cryptographic foundations crumbling under advancing quantum tech.
Wood’s reversal stings because he was an early bull, adding Bitcoin in 2020 amid stimulus fears and boosting to 10% in 2021. Bitcoin delivered 325% gains since then, trouncing gold’s 145%, yet Wood now sees performance as irrelevant. The quantum computing threat looms as the real killer, potentially shattering Bitcoin’s security model in years, not decades. As institutions rethink allocations, this shift could ripple through pension funds and beyond, questioning if Bitcoin is truly digital gold or just a high-tech house of cards.
Institutional capital doesn’t move on whims, and Wood’s Greed & Fear newsletter lays bare the reasoning. Quantum advances could let cryptographically relevant quantum computers (CRQCs) derive private keys from public ones, exposing wallets overnight.

Why a Bitcoin Bull Turned Bear
Christopher Wood’s pivot marks a seismic change in how Wall Street views Bitcoin. Once a vocal advocate, he now deems the quantum computing threat too pressing for long-horizon investors like pension funds. His model portfolio trim reallocates evenly to physical gold and miners, favoring assets untouched by code vulnerabilities. This isn’t isolated; it reflects growing chatter among allocators that Bitcoin’s store-of-value narrative has cracks.
Wood first embraced Bitcoin in December 2020, riding pandemic-era debasement fears. By 2021, exposure hit 10%, capturing massive upside. But recent newsletter editions flip the script, prioritizing durability over returns. Gold, with its millennia-tested hedge status, emerges as the beneficiary, free from governance debates or tech disruptions. As Cardano AI quantum computing discussions heat up, alternatives positioning against quantum risks gain traction.
The shift underscores a broader institutional recalibration. Performance metrics fade when existential risks surface. Wood’s call amplifies voices warning that Bitcoin’s security budget shrinks post-halvings, inviting attacks. For context on halvings and miner woes, see our piece on Bitcoin hash rate falls.
Wood’s Greed & Fear Rationale
Wood’s Greed & Fear explicitly flags quantum computing as nearer than assumed. “There is growing concern in the Bitcoin community that quantum computing could only be a few years away rather than a decade or more,” he writes. This urgency stems from CRQCs potentially reversing elliptic curve cryptography, Bitcoin’s backbone. Private keys become derivable, turning secure holdings into loot.
Bitcoin’s protocol relies on asymmetric crypto where public keys hide privates. Quantum’s Shor’s algorithm changes that, enabling attacks in hours. Wood argues this erodes multi-decade store-of-value appeal. Institutions demand certainty; gold offers it without firmware updates or forks. Meanwhile, Bitcoin’s 325% outperformance since 2020 feels like yesterday’s news against infinite loss potential.
Bloomberg spotlighted Wood’s exit, noting how theoretical risks now shape portfolios. This mainstreaming pressures Bitcoin devs to act, but solutions lag. For related governance shifts, explore Binance proof of reserves.
Performance vs. Durability Tradeoff
Bitcoin crushed gold post-allocation, yet Wood dismisses it. Gains don’t mitigate total wipeout risk. Pension investors prioritize capital preservation over alpha chases. Quantum threats amplify this, questioning if Bitcoin survives unscathed into 2030s. Gold’s steady climb lacks such drama, appealing to risk-averse capital.
Analysis shows vulnerable addresses holding millions in BTC: Satoshi-era P2PK, lost coins, reused keys. Coinbase estimates 6.5 million BTC exposed long-term. Migration demands hard forks, clashing with immutability ideals. Wood’s reallocations signal others may follow, especially as BlackRock Bitcoin ETF themes evolve.
Quantum Risk Exposed: Bitcoin’s Crypto Underbelly
The quantum computing threat isn’t sci-fi; it’s a protocol-level vulnerability hitting Bitcoin hardest. Current computers can’t crack ECDSA signatures efficiently, but quantum rigs could. This pits developers against capital allocators, with governance as the battleground. Proposed fixes like post-quantum migrations or coin burns spark property rights firestorms.
Nic Carter of Castle Island Ventures highlights the divide: capital seeks solutions, devs deny urgency. Price already reflects this tension. Vulnerable supply—P2PK, dormant wallets—could flood markets if cracked. Coinbase’s David Duong warns of broader economic model risks, urging proactive upgrades. As quantum tech accelerates, Bitcoin’s timeline compresses.
This debate tests Bitcoin’s antifragility. Forks have happened, but quantum-scale changes threaten core tenets. Institutions like Jefferies balk at invalidated holdings undermining credibility. For quantum-resistant plays, see Solana quantum resistant.
Vulnerable Addresses Breakdown
Satoshi-era P2PK addresses top the list, exposing millions in unmoved BTC. Reused addresses and lost coins compound risks. Quantum attacks target public keys revealed in spends. Estimates peg 6.5 million BTC at jeopardy, per Coinbase. This isn’t fringe; it’s math.
Duong stresses long-range threats beyond keys, hitting security models. Current quantum tech falls short, but timelines shrink. Migration to lattice-based crypto demands consensus, tricky in decentralized networks. Failure risks mass exodus, validating Wood’s caution.
Governance Nightmares Ahead
Solutions like burning vulnerable coins or forced migrations clash with HODL ethos. Property rights debates echo Mt. Gox recoveries. Forks risk chain splits, diluting value. Dev denial, per Carter, weighs on sentiment. Capital demands clarity; silence erodes trust.
Institutional Voices Amplify the Warning
Beyond Wood, figures like Justin Bons predict Bitcoin collapse post-2033. Shrinking subsidies and low fees invite 51% attacks costing under $3 million daily. Double-spends could nuke exchanges. This chorus pressures Bitcoin’s narrative as institutions pivot.
Coinbase echoes concerns, flagging economic vulnerabilities. Gold benefits as a neutral store, sans tech baggage. Broader rethink questions Bitcoin’s edge over traditional assets. As gold price surge narratives build, reallocations accelerate.
Bons’ Collapse Prediction
Bons foresees mining collapse as block rewards halve, fees insufficient. Security budget shrinks, enabling cheap attacks. Inflation hikes to counter would fork the chain. Billions in exchange double-spends loom profitable. Timeline: 7-11 years.
This dovetails quantum risks, compounding threats. Short-term holders already rattled, per market data. Long-term, viability hinges on upgrades.
Coinbase’s Broader Risk View
Duong outlines quantum’s multi-layer impact: keys, economics, security. 6.5M BTC vulnerable demands action. Post-quantum shift essential, years out. Institutional rethink underway.
What’s Next
Bitcoin faces a credibility test as quantum computing threat mainstreams. Devs must bridge governance gaps without alienating holders. Institutions may diversify into quantum-hedged assets like gold or upgraded chains. Watch for migration proposals; inaction accelerates outflows. Meanwhile, check Bitcoin in 2026 for cycle peaks amid risks. The market decouples hype from reality—survival demands adaptation, not denial.
Gold’s resurgence underscores timeless appeals. Bitcoin bulls counter with upgrade paths, but timelines matter. As Wall Street reallocates, retail HODLers ponder if digital scarcity withstands quantum scrutiny. Stay tuned; this unfolds fast.
