Quantum computing is no longer an abstract theory. It is fast becoming a real risk to global finance. Experts warn that it could break the cryptographic foundations that protect Bitcoin.
It was once viewed as a distant, futuristic idea. Today, it has become a real threat to digital assets. A report from the Human Rights Foundation (HRF) warns that this technology could disrupt the foundations of cryptocurrency security.
Quantum Computing Puts Billions in Bitcoin at Stake
The HRF report clarifies in its own way: Bitcoin is not only an investment. For activists and journalists, who have to live under dictatorial authorities, it is a tool to preserve their money.
This is the only way for them to save up money and make donations without the government’s view.. But it is possible solely thanks to cryptography. Quantum computing technology can overcome such a barrier. So far, up to $690 million of Bitcoin could be stolen.

It is the Bitcoin equivalent of about 6.5 million coins. However, it is possible to save about 4,49 million of them. The money moved to the subroutine addresses might indeed be untouchable.
The Growing Quantum Computing Threat
Quantum computing works differently from traditional computing. It uses quantum bits, or qubits, to process massive amounts of data at once. This makes it capable of solving complex problems that would take normal computers centuries.
Bitcoin’s entire network depends on private and public key cryptography. Quantum computing could, in theory, calculate private keys from public ones. That would allow attackers to steal funds directly.
How Quantum Attacks Work
The HRF report identifies two types of quantum attacks. Long-range attacks target old or reused Bitcoin addresses. These attacks use exposed public keys to recover private keys. Short-range attacks are more dangerous.
They exploit active transactions, stealing funds before the network confirms them. Both forms could become possible once quantum computing reaches sufficient power.
Bitcoin’s Upgrade Dilemma
Bitcoin’s decentralized nature makes it strong, but also slow to adapt. Unlike centralized systems, Bitcoin cannot issue quick updates. Every change must go through global consensus. That process can take years.
Crypto analyst Nic Carter said that quantum computing is Bitcoin’s biggest threat. He noted that most financial systems could patch their software easily. Bitcoin cannot. Developer Jameson Lopp added that apathy could be an even greater danger. If users ignore the risk, no upgrade will matter.
Divisions Over the Fix
The community is split on how to respond. Some argue that developers should “burn” or freeze coins that are vulnerable. Others say this would violate Bitcoin’s principles of property rights and decentralization. The debate shows how complex this challenge is.
Quantum computing forces Bitcoin to balance between innovation and ideology. Protecting the network may require decisions that go against its founding philosophy of neutrality and freedom.
Building Quantum-Resistant Solutions
Developers are working on new cryptographic systems. The HRF highlights two main solutions: lattice-based and hash-based signatures. Both are designed to resist quantum computing attacks. But they come with trade-offs.
Lattice-based signatures are ten times larger than current ones. Hash-based signatures are even heavier, about 38 times bigger.
These larger signatures would slow the network, increase blockchain size, and require stronger hardware. That means wallet upgrades, software changes, and retraining for node operators.
The Global Coordination Challenge
Quantum computing will force the Bitcoin ecosystem to cooperate like never before. Developers, miners, wallet makers, and users will need to work together. Even small upgrades in Bitcoin take years to complete. Quantum-proofing the entire network will be a far greater task.
The HRF warns that without global coordination, millions of coins could be lost. Education and outreach are critical. Many holders still don’t know that their coins are vulnerable. The transition to quantum-resistant systems must happen before practical quantum computers arrive.
Quantum computing is advancing faster than many expected. Governments and tech giants are investing billions in its development. The timeline for a functional quantum computer is uncertain, but the risk is real. Every year without preparation increases the danger. Bitcoin’s future depends on proactive defense, not denial.
Conclusion
Quantum computing is both an innovation and a danger. For Bitcoin, it is bound to be an existential threat and a contradiction to the values on which Bitcoin was built. The HRF calls on the planet to act before the late upcoming of the innovative breakthrough.
Bitcoin preservation needs improved technical measures, client knowledge, and the coming together of its society. Otherwise, the most famous currency on the Earth would be open to a kind of secretive debacle never seen before.

Frequently Asked Questions Quantum Computing
1- What makes quantum computing dangerous for Bitcoin?
It poses a threat because it can break the cryptographic keys that form the foundation of Bitcoin wallets and transactions.
2- How much Bitcoin is in immediate danger due to quantum attacks?
Approximately 6.5 million coins can become vulnerable to quantum attacks.
3- What are quantum-resistant addresses?
The addresses utilize entirely new cryptographic systems that are robust to quantum computing due to the result of quantum safe-cryptography research.
4- What can users do to protect their coins from quantum attacks?
Once quantum safe wallets are available, users are urged to move all their funds to these wallets from old or reused addresses.
