Bitcoin's Price Under Pressure: The Flow of Quantum Risk

The direct financial impact of quantum risk is now visible in institutional portfolios. Jefferies strategist Christopher Wood removed a 10% Bitcoin position from his flagship model portfolio earlier this month, reallocating to physical gold and mining equities. He cited specific concerns that quantum computing could break Bitcoin's Elliptic Curve Digital Signature Algorithm (ECDSA) keys, directly challenging its store-of-value thesis.

This strategic move coincided with a notable shift in asset performance. Bitcoin has underperformed gold in 2026, with the BTC/gold ratio at 19.26 in January 2026. This divergence is being attributed to quantum risk rather than traditional market forces, as institutional investors begin treating these threats as more than theoretical.

The primary vulnerability lies in specific address types. Funds stored in legacy Pay-to-Public-Key scripts are at risk because the public key is exposed on-chain after a transaction, creating a window where a sufficiently powerful quantum computer could derive the private key and steal those specific coins.

Quantifying the Exposed Asset Base

The timeline for a quantum threat is now measurable. Blockchain analytics firm Chainalysis estimates that sufficiently powerful quantum systems capable of cracking Bitcoin's core cryptography could emerge within 10 to 15 years. This sets a firm countdown for the industry, moving the threat from theoretical to a tangible, long-term risk.

The primary attack vector is already active. Malicious actors are likely conducting "store now, decrypt later" attacks, harvesting and storing public-key data today for future decryption when quantum machines mature. This creates a latent vulnerability that could be exploited years down the line.

The exposed asset base is substantial. The theoretical break of ECDSA via Shor's algorithm threatens the core cryptography of Bitcoin and Ethereum. Specifically, legacy Pay-to-Public-Key addresses, which hold an estimated hundreds of billions of dollars' worth of BTC, are at risk because their public keys are exposed on-chain after a transaction. This creates a permanent window for decryption that persists until these funds are moved to quantum-resistant addresses.

Market Metrics and Price Impact

The market is pricing in quantum risk through a clear divergence in asset performance. Bitcoin has underperformed gold by 6.5% year-to-date, a stark move that analysts attribute to institutional concerns over cryptography, not traditional macro forces. This underperformance is crystallized in the BTC/gold ratio, which stood at 19.26 in January 2026, a level signaling heightened risk perception.

The institutional shift is becoming a visible flow. Jefferies strategist Christopher Wood's recent removal of a 10% Bitcoin position from his model portfolio, reallocating to gold and mining equities, is a concrete signal. While other major institutions like Harvard and Morgan Stanley show continued or increased support, Wood's move exemplifies a growing cohort treating quantum threats as a material, long-term risk that warrants portfolio defense.

The key metric to watch is whether such reallocations become more widespread. The current price action suggests the market is beginning to assign a tangible cost to this existential risk. As more capital flows into perceived safe havens like gold, the pressure on Bitcoin's price and its relative valuation against traditional stores of value will likely persist, at least until the quantum threat timeline becomes clearer or mitigations gain broad adoption.
