Quantum Panic Over Bitcoin? CoinShares Says Relax, the Network Isn’t Breaking Anytime Soon
Quantum Threat to Bitcoin: Why Experts Say Investors Should Stay Calm, Not Panic
Concerns about the so-called “quantum threat” to Bitcoin are resurfacing as advances in quantum computing continue to make headlines. The idea that future machines could one day crack cryptographic systems has fueled anxiety among some investors, raising questions about whether Bitcoin’s security model could face an existential risk.
However, a recent analysis from CoinShares suggests that these fears may be overstated. Rather than an imminent danger, researchers describe quantum computing as a long-term engineering challenge—one that the Bitcoin ecosystem is likely to have ample time to prepare for.
According to hokanews, the growing discussion reflects healthy scrutiny of a global digital asset, not a signal of an approaching crisis.
Why the Quantum Threat Is Getting Attention
Quantum computing has long been discussed as a potential disruptor of modern cryptography. Unlike classical computers, quantum machines can process information in fundamentally different ways, potentially enabling them to solve certain mathematical problems much faster.

Because Bitcoin relies on cryptographic algorithms to secure transactions and wallets, the idea that quantum computers could eventually break those protections has captured public attention. As quantum research accelerates, the topic has moved from theoretical debate into mainstream investor conversation.
Still, most experts agree that the gap between today’s technology and a system capable of threatening Bitcoin remains enormous.
CoinShares: The Risk Is Smaller Than It Appears
In its latest report, CoinShares examined how much Bitcoin could realistically be exposed if quantum computing advanced far beyond current capabilities. The firm concluded that only around 10,200 BTC are held in addresses large enough to meaningfully disrupt markets if compromised.
While an estimated 1.6 to 1.7 million BTC exist in older address formats that could theoretically be more exposed, the majority of Bitcoin today is stored in modern wallets with stronger protections. These newer address types hide public keys until funds are spent, significantly reducing the attack surface.
To break Bitcoin’s elliptic curve cryptography directly, researchers estimate that quantum computers would require close to 13 million qubits. Today’s most advanced machines operate at a fraction of that scale. Most projections place such capabilities sometime in the 2030s at the earliest, with practical attacks likely much further away.
From this perspective, the threat appears distant rather than urgent.
Why Bitcoin’s Security Model Still Holds
Bitcoin’s design incorporates multiple layers of security that go beyond a single cryptographic assumption. Transaction authorization relies on elliptic curve signatures, while proof-of-work and hashing secure the blockchain itself.
Even in a hypothetical quantum future, experts note that a powerful computer would not be able to rewrite Bitcoin’s fixed 21 million supply, bypass proof-of-work, or instantly take control of the network. Any realistic attack would be limited in scope and constrained by network rules.
Moreover, Bitcoin is not static. Developers have long discussed the possibility of introducing post-quantum cryptography through software upgrades, such as soft forks, well before quantum machines become powerful enough to pose a real threat.
Disagreements Among Experts
Despite the reassuring conclusions from CoinShares, not all researchers agree on the scale of the risk. Some warn that downplaying the threat could lead to complacency.
Joseph Kearney, who focuses on the intersection of quantum computation and blockchain technology, has criticized claims that quantum computers must be “100,000 times stronger” before posing any concern. He argues that such language could oversimplify a complex and evolving field.

Additional data from the Project Eleven tracker paints a more cautious picture. It estimates that up to 6.8 million BTC could be theoretically vulnerable under advanced conditions. That figure represents hundreds of billions of dollars in potential exposure, though it does not imply that these coins could be stolen overnight.
Many of the addresses included in higher vulnerability estimates belong to long-dormant wallets. Exploiting them would still require breakthroughs that do not yet exist.
Vulnerable Does Not Mean Immediately At Risk
One key point often lost in public debate is the difference between theoretical vulnerability and practical exploitability. Even if quantum computers reached sufficient scale, coordinated attacks would face technical, logistical, and detection challenges.
Analysts emphasize that any unusual activity involving compromised keys would likely be visible on-chain, giving the network time to respond. Bitcoin’s transparent ledger and global monitoring reduce the chances of a silent, catastrophic failure.
As CoinShares notes, users can also mitigate exposure by moving funds from older address types to modern wallets, a step that significantly lowers risk without requiring any protocol changes.
Would Markets Actually Panic?
Market impact is another area where fears may be exaggerated. Even under extreme assumptions, analysts estimate that only around 10,000 BTC could realistically enter circulation from compromised keys in a short time frame.
Compared with Bitcoin’s daily trading volumes, such an amount would likely resemble routine selling pressure rather than a systemic shock. History shows that markets have absorbed far larger events without long-term disruption.
There is also a broader context to consider. If quantum computers became powerful enough to crack Bitcoin’s cryptography, they would pose an even greater threat to banks, payment networks, military systems, and secure internet communications.
In that scenario, Bitcoin would not be the first or only system affected. Quantum computing would represent a global cybersecurity challenge, not a crypto-specific problem.
Preparing for a Post-Quantum Future
The Bitcoin community has a track record of adapting to emerging risks. Over the years, the network has undergone multiple upgrades to improve security, efficiency, and scalability.
Post-quantum cryptography is already an active area of research, and developers are closely monitoring progress in quantum computing. If needed, new cryptographic standards could be introduced gradually, giving users time to transition.
This ability to evolve is a critical reason many experts believe Bitcoin is well positioned to face long-term technological shifts.
A Long-Term Engineering Challenge, Not a Crisis
The debate surrounding the quantum threat to Bitcoin reflects the maturity of the asset. As Bitcoin has grown into a multi-trillion-dollar market, scrutiny of its long-term security has intensified.
Current evidence suggests the risk is limited, manageable, and still years—if not decades—away. While continued research and preparation are necessary, there is little indication that quantum computing poses an immediate danger to Bitcoin’s integrity.
Conclusion
The quantum threat to Bitcoin remains a topic worth monitoring, but not one that demands panic. Reports from CoinShares and other analysts indicate that the danger is often overstated and poorly understood outside technical circles.
Rather than an investment-ending event, quantum computing appears to be a future engineering challenge—one the Bitcoin ecosystem has both the time and tools to address. With upgrade paths available and increasing awareness across the industry, Bitcoin is likely to adapt long before quantum machines become a real-world threat.
