Bitcoin advocate Michael Saylor has recently downplayed concerns over quantum computing’s potential impact on Bitcoin, calling the fear campaign little more than a marketing ploy by promoters of so-called quantum-resistant altcoins.

In a June 6 interview on CNBC’s Squawk Box, the Strategy Corporation executive chairman dismissed quantum-related fears as exaggerated narratives designed to sell alternative crypto assets. “This is mostly marketing by people who want to sell you the next quantum ‘yo-yo token,’” Saylor stated plainly.
Understanding the Quantum Computing Concern
Quantum computing has long been discussed in cryptographic circles as a theoretical threat to public-key cryptography, including the elliptic curve cryptography (ECC) that secures Bitcoin wallets. If a sufficiently powerful quantum computer were built, it could potentially derive private keys from public ones—allowing unauthorized access to funds.
According to research from Project Eleven, an organization focused on quantum and blockchain security, approximately 10 million Bitcoin addresses have exposed public keys. Should quantum computers advance enough to break 256-bit ECC encryption, over 6 million BTC could be at risk—representing a significant portion of the total supply.
Despite this, Saylor argues that such fears are overblown and often exploited for commercial gain rather than grounded in realistic near-term threats.
Why Real-World Quantum Threats Are Unlikely
Saylor emphasized that even if tech giants like Google or Microsoft developed quantum machines capable of breaking modern encryption, they would have no incentive to release or market them. Doing so would destabilize the very infrastructure these companies—and national economies—rely upon.
“Google and Microsoft will never sell a computer that breaks modern cryptography because it would destroy Google, Microsoft, the U.S. government, and the entire banking system,” he explained.
The logic is straightforward: widespread decryption capability would not only compromise Bitcoin but also collapse digital trust across email, cloud storage, financial systems, and national defense networks. No responsible entity would unleash such chaos intentionally.
Moreover, Saylor pointed out that any actual breakthrough in quantum decryption would likely be classified and weaponized by intelligence agencies—not sold publicly or used to undermine open blockchain networks first.
Bitcoin’s Ability to Adapt and Upgrade
One of Saylor’s strongest arguments lies in Bitcoin’s proven ability to evolve. Should a credible quantum threat ever emerge, he asserts, the solution would be both feasible and swift.
“The fix is simple: upgrade the Bitcoin network—both hardware and software,” Saylor said. “Just like Microsoft, Google, or the U.S. government upgrades their systems when vulnerabilities appear, we can do the same with Bitcoin.”
Bitcoin’s open-source development community could implement quantum-resistant cryptographic algorithms—such as lattice-based cryptography or hash-based signatures—through a coordinated consensus upgrade. Given precedent with past upgrades like SegWit and Taproot, such a transition, while complex, is entirely within reach.

Quantum Risk vs. Everyday Threats
Saylor stressed that everyday risks far outweigh theoretical quantum attacks. Users are 10,000 times more likely to lose their Bitcoin through phishing scams, malware, or poor key management than through quantum decryption.
“This is the hardest system in the world to crack,” Saylor noted. “Hackers will go after your bank account, your Google login, your Microsoft credentials—anything else—because those systems are an order of magnitude less secure.”
Most real-world breaches occur at the user level: weak passwords, unsecured devices, or social engineering tactics. In contrast, Bitcoin’s decentralized architecture and cryptographic foundation remain unbroken after more than 15 years of continuous operation.
Project Eleven’s Q-Day Challenge
To test the urgency of quantum threats, Project Eleven launched a competition in April aimed at assessing how close quantum computers are to cracking Bitcoin’s encryption. Dubbed the “Q-Day Prize,” the initiative encourages researchers to use quantum technology to break parts of Bitcoin’s cryptographic keys within a one-year timeframe.
The goal isn’t to harm Bitcoin but to measure the timeline of emerging risks and accelerate the development of post-quantum cryptographic solutions that can protect decentralized networks long-term.
Currently, experts estimate that around 2,000 logical qubits (error-corrected) would be required to break a full 256-bit ECC key—the type used by Bitcoin. However, today’s most advanced chips fall far short:
- IBM’s Heron processor: 156 qubits
- Google’s Willow chip: 105 qubits
While progress is being made, current quantum machines lack the stability, error correction, and coherence time needed for practical cryptanalysis. Physical qubits must be massively scaled and corrected before they can form usable logical qubits—making large-scale attacks unlikely for years, if not decades.
Frequently Asked Questions (FAQ)
Q: Can quantum computers currently break Bitcoin’s encryption?
A: No. Current quantum computers lack sufficient qubits and error correction capabilities. Breaking Bitcoin’s ECC requires thousands of stable logical qubits—technology still years away.
Q: What would happen if someone built a quantum computer powerful enough to attack Bitcoin?
A: The Bitcoin community could respond with a protocol upgrade using quantum-resistant cryptography. Historical upgrades show the network can adapt to new threats without losing integrity.
Q: Are all Bitcoin addresses vulnerable to quantum attacks?
A: Only addresses with exposed public keys (e.g., reused addresses) are theoretically vulnerable. Using fresh addresses for each transaction (as recommended) significantly reduces this risk.
Q: How can I protect my Bitcoin from future threats?
A: Use modern wallets that generate new addresses per transaction, enable multi-signature setups, store private keys securely offline, and stay informed about protocol upgrades.
Q: Is the quantum threat just hype?
A: While not entirely fictional, the immediate danger is minimal. Much of the discussion is amplified by projects promoting their own “quantum-safe” tokens—a trend Saylor criticizes as fear-based marketing.

Final Thoughts
Michael Saylor’s stance reflects a broader principle in technology resilience: systems evolve in response to threats. While quantum computing represents a future challenge, it is neither imminent nor insurmountable for Bitcoin.
Rather than fearing hypothetical breakthroughs, users should focus on proven best practices—secure key management, cold storage, and staying updated with network developments.
The narrative around quantum risk often distracts from real vulnerabilities: human error and poor security hygiene. By prioritizing education and preparedness, the crypto community can maintain confidence in Bitcoin’s longevity—even in the face of advancing technology.
