Quantum computing is already affecting the cryptocurrency industry in several notable ways, and Bitcoin is increasingly at the center of that shift as investors reassess long-term technological risk. While fully capable quantum machines remain years away, their anticipated arrival is beginning to influence market behavior today, not through broken encryption, but through changing confidence.
One signal has been Bitcoin’s recent lag behind gold, a divergence that has caught the attention of institutional investors. Some strategists now argue that emerging quantum capabilities introduce a new category of risk that traditional valuation models struggle to price in. That uncertainty is starting to weigh on Bitcoin’s appeal as a long-term hedge and portfolio decisions are already reflecting this concern.
BeInCrypto recently reported that Jefferies strategist Christopher Wood removed a Bitcoin allocation from his widely followed “Greed & Fear” model portfolio, redirecting that exposure toward physical gold and mining stocks. Wood pointed to the possibility that future quantum systems could undermine the cryptographic foundations that secure Bitcoin transactions, altering its role as a digital store of value.
Industry observers say this thinking is spreading beyond a single portfolio. Market commentators note that many advisors now treat quantum risk as a structural overhang rather than a distant hypothetical. One widely followed analyst on X argued that until mitigation plans are clearly defined, quantum computing will continue to suppress Bitcoin allocations among cautious investors, regardless of near-term price action.
A 2025 study by Chaincode Labs estimated that a sizable share of existing Bitcoin addresses could be exposed to future quantum attacks because their public keys have already been revealed through past transactions. Depending on assumptions, millions of Bitcoin could theoretically become vulnerable if sufficiently powerful quantum machines emerge and no protocol changes are implemented beforehand.
Hardware trends help explain why this issue is gaining urgency across the cryptocurrency industry. Quantum processors have been scaling rapidly, and recent milestones from major technology firms have reinforced expectations that cryptographically relevant quantum computers may arrive sooner than once assumed. Projection models tracking qubit growth suggest a steep acceleration curve, narrowing the window for proactive security upgrades.
Bitcoin’s governance model complicates the response to quantum computing and crypto security. Unlike centralized financial institutions that can mandate cryptographic changes, Bitcoin relies on broad consensus across developers, miners, exchanges, and node operators. Any transition to quantum-resistant signatures would require coordination across a fragmented ecosystem, with no authority capable of enforcing rapid adoption.
Some researchers who once dismissed quantum threats now take a more cautious stance. Analysts increasingly acknowledge that while technical solutions exist in theory, deploying them across a decentralized network is a slow and politically complex process. That coordination challenge may be the most immediate way quantum computing is already influencing Bitcoin’s market narrative.
It would be interesting to hear what tech companies like D-Wave Quantum Inc. (NYSE: QBTS) focused on advancing quantum computing have to say about the growing fears about the likely adverse effects of quantum computing on the crypto industry.
