Viewpoint: If the Quantum Computing Risk Is Solved, Bitcoin Could Rise to $1 Million
A prominent investor has put a high-profile condition on one of the most ambitious Bitcoin price forecasts: the crypto industry must first address the threat posed by quantum computing.
In a recent interview with The Rollup, Kevin O’Leary argued that Bitcoin could eventually reach $1 million if the market gains confidence that quantum computers will not compromise the network’s cryptographic security. His view highlights a question that is becoming increasingly relevant for long-term Bitcoin investors:
Can Bitcoin remain secure as computing technology evolves?
The issue is not simply whether quantum computers will make Bitcoin’s price go up or down. It concerns the resilience of digital signatures, the security of dormant coins, institutional custody standards, and the ability of a decentralized network to coordinate a large-scale cryptographic upgrade.
Why Quantum Computing Matters to Bitcoin
Bitcoin relies on cryptography at several critical points. Ownership is demonstrated through digital signatures, while public-key cryptography helps ensure that only the holder of the corresponding private key can authorize a transaction.
The current Bitcoin ecosystem uses elliptic-curve cryptography, including ECDSA and Schnorr signatures. Schnorr signatures are specified in BIP 340, which was introduced as part of Bitcoin’s Taproot upgrade.
A sufficiently powerful, fault-tolerant quantum computer could theoretically use Shor’s algorithm to derive a private key from a publicly exposed public key. That would create a very different risk from today’s common threats, such as phishing, malware, or exchange failures. Instead of attacking individual users, a quantum adversary could potentially challenge the mathematical assumptions supporting a large number of addresses.
However, the risk is more nuanced than the phrase “quantum computers can break Bitcoin” suggests.
Many Bitcoin addresses initially reveal only a hash of the public key. The public key becomes visible when coins are spent from the address. This means that coins whose public keys have not been exposed may have a different risk profile from coins that have already been spent or remain in reusable addresses. The Bitcoin Optech overview of quantum resistance provides a useful explanation of the technical considerations involved.
The central concern is therefore not just the arrival of a quantum computer. It is whether Bitcoin can transition to quantum-resistant signatures before an attacker can exploit exposed keys.
“Q-Day” Is a Coordination Problem, Not Just a Technology Problem
The term “Q-Day” generally refers to the point at which quantum computers become capable of breaking widely used public-key cryptography at practical scale. No one can reliably predict when that point will arrive. It may be many years away, and the engineering challenges involved in building large, fault-tolerant quantum systems remain substantial.
That uncertainty does not eliminate the need for preparation.
The National Institute of Standards and Technology has already finalized its first post-quantum cryptographic standards. The broader lesson is that cryptographic migration can take a long time, particularly when systems are open, global, and difficult to upgrade.
For Bitcoin, a transition would likely involve several difficult decisions:
- Selecting one or more quantum-resistant signature schemes
- Designing a migration path for existing coins
- Protecting users who lose access to their old keys
- Deciding how to treat coins that remain in vulnerable address types
- Coordinating software upgrades among miners, node operators, developers, exchanges, custodians, and individual holders
- Managing the political and economic consequences of a potentially contentious protocol change
This is why quantum resistance is not merely a cryptography issue. It is also a governance, infrastructure, and risk-management issue.
A technically sound solution would not automatically guarantee a smooth transition. Bitcoin’s value proposition depends partly on predictable monetary rules and decentralized decision-making. Any emergency-style upgrade could create disagreement among stakeholders, even if the underlying security rationale were widely accepted.
Why Quantum Security Could Influence Institutional Demand
O’Leary’s argument connects quantum risk to institutional adoption. Large investors typically evaluate more than price performance. They also examine custody, legal enforceability, operational controls, market liquidity, and the durability of the underlying infrastructure.
For an institution allocating capital over decades, an unresolved cryptographic risk could become a reason to limit exposure. Even if the probability of a successful quantum attack is low, the potential damage could be severe. This is especially relevant for long-term custodians holding assets that may remain untouched for years.
Solving the issue—or establishing a credible and widely accepted migration plan—could remove one of the objections faced by Bitcoin as a strategic asset. It would not guarantee a higher price, but it could strengthen the argument that Bitcoin is suitable for long-duration portfolios.
That distinction matters. A quantum-resistant upgrade would be a foundation for confidence, not a direct valuation mechanism.
Bitcoin would still need to compete with other assets for liquidity and investor attention. Macro conditions, regulation, market structure, monetary policy, and adoption would remain decisive. The $1 million scenario therefore depends on a combination of factors rather than a single technical breakthrough.
A More Fragmented Blockchain Market
O’Leary has also revised his earlier view that Bitcoin and Ethereum would capture most of the value generated by the crypto industry. He now questions whether Ethereum will become the sector’s final standard, citing concerns about its speed and security, and instead expects different industries to use different blockchains for tokenization.
This perspective reflects a broader shift in how blockchain infrastructure is being evaluated. Rather than asking which network will dominate every use case, investors are increasingly examining whether a chain is well suited to a particular application.
A financial institution issuing tokenized securities may prioritize compliance tools, privacy, finality, and integration with existing systems. A consumer application may focus on transaction costs and throughput. A decentralized financial protocol may emphasize composability and liquidity. These requirements do not necessarily point to one universal blockchain.
Tokenization could therefore produce a multi-chain market in which networks specialize by geography, asset type, sector, or regulatory environment. Interoperability and secure cross-chain communication may become just as important as the performance of any individual chain.
For Bitcoin, this could reinforce its role as a monetary and settlement asset rather than an all-purpose application platform. Ethereum and other smart contract networks may compete for tokenized assets and decentralized applications, while new chains target specific institutional or industry requirements.
The AI Investment Thesis Is Also an Infrastructure Thesis
O’Leary’s comments on artificial intelligence follow a similar logic. Instead of selecting individual AI models, he has focused on the infrastructure required to run them, particularly electricity generation and uranium-related assets.
This approach is relevant to the blockchain sector because both AI and crypto depend on large-scale physical infrastructure. Data centers, semiconductor supply chains, energy markets, network connectivity, and specialized hardware all shape the economics of digital technologies.
The rising energy demand from AI may also influence Bitcoin mining markets. Competition for power could increase operating costs in some regions, while surplus renewable generation or advanced nuclear technologies could create new opportunities in others. The relationship between digital assets and energy infrastructure is therefore likely to remain an important investment theme.
At the same time, energy availability alone does not determine whether a blockchain network is sustainable or economically competitive. Investors must also consider grid stability, local regulation, capital expenditure, mining hardware efficiency, and the ability to respond to changes in digital-asset prices.
Regulation Remains a Key Variable
Technology is only one part of the institutional adoption equation. Regulation remains equally important.
O’Leary has expressed doubt that the proposed Clarity Act would advance before the U.S. midterm elections, suggesting that lawmakers may revisit bipartisan digital-asset market legislation afterward. The exact timetable remains uncertain, but the broader issue is clear: regulatory definitions and market-structure rules could significantly influence which blockchain networks attract institutional capital.
Clearer rules could support innovation, improve compliance standards, and encourage more traditional financial firms to participate. Delayed or fragmented regulation could have the opposite effect, pushing activity toward jurisdictions with more predictable frameworks.
For Bitcoin, regulatory clarity may be particularly important because institutional demand depends on reliable custody, reporting, taxation, and market-access rules. Quantum security could remove one technical concern, but it would not resolve these legal and operational questions.
What Bitcoin Holders Can Do Today
The possibility of future quantum attacks should not lead users to abandon basic security practices. Most real-world losses today still result from compromised seed phrases, phishing, malicious software, exchange failures, or poor backup procedures—not quantum computers.
Bitcoin holders can focus on several practical measures:
- Avoid exposing private keys or recovery phrases online.
- Use hardware-based key storage for significant long-term holdings.
- Verify transaction details on a trusted device before signing.
- Keep recovery backups offline and protect them from unauthorized access.
- Avoid unnecessary address reuse where possible.
- Follow credible Bitcoin development discussions as post-quantum proposals mature.
- Treat future protocol upgrades carefully and verify software sources before installation.
A hardware wallet cannot make Bitcoin quantum-resistant by itself. Its primary role is to reduce exposure to internet-connected malware and keep signing operations isolated. If Bitcoin eventually adopts new signature schemes, users will still need to migrate funds to compatible address types and follow the relevant security procedures.
For users who value offline signing, transaction verification, and secure key management, OneKey hardware wallets can serve as part of a broader self-custody strategy. The device should be viewed as one layer of protection—not a substitute for careful backup management, software verification, and awareness of future protocol changes.
The $1 Million Question
Bitcoin reaching $1 million would require more than a successful response to quantum computing. It would likely depend on sustained demand, deeper institutional participation, favorable market infrastructure, regulatory clarity, and continued confidence in Bitcoin’s monetary properties.
Nevertheless, the quantum question deserves attention because it goes to the heart of Bitcoin’s long-term credibility. If the ecosystem can develop and coordinate a practical migration to quantum-resistant cryptography before the threat becomes urgent, one significant objection to Bitcoin’s future could be reduced.
O’Leary’s forecast should therefore be read less as a precise price prediction and more as a challenge to the industry: long-term value depends on solving long-term security problems.
The networks that ultimately succeed may not be those with the loudest short-term narratives. They may be the ones capable of adapting their infrastructure, coordinating upgrades, protecting users, and earning institutional trust over decades.
