The post CoinShares: Quantum Computing Threat to Bitcoin Is ‘Manageable,’ Not Immediate appeared first on Coinpedia Fintech News

The progress of quantum computing has raised new questions about the long-term security of Bitcoin, but digital asset manager CoinShares says the threat remains distant and manageable. According to the firm, while quantum computers could one day challenge certain cryptographic systems used by Bitcoin, the technology required to do so is still many years away.

Experts say discussions about quantum risks are important for a financial system that now secures trillions of dollars in value. However, current evidence suggests the issue is more of a future engineering challenge than an immediate danger.

How Quantum Computers Could Affect Bitcoin Bitcoin’s security relies mainly on two technologies: digital signatures that authorize transactions and cryptographic hashing that protects addresses and powers mining. Advanced quantum algorithms could, in theory, weaken parts of these systems, potentially allowing attackers to calculate private keys from exposed public keys.

Even in such a scenario, the exposure would be limited. Most modern Bitcoin addresses keep their public keys hidden until funds are spent, which means they remain protected. Older address types that reveal public keys represent only a small portion of total supply, reducing the potential impact on the broader market.

Technology Still Far From Practical Attacks CoinShares says that quantum computers capable of breaking Bitcoin’s encryption would require millions of highly stable qubits, far beyond today’s machines. Current quantum systems operate with only a tiny fraction of the computing power needed for such tasks, and researchers estimate that practical quantum attacks could still be a decade or more away.

This long development timeline gives developers and users sufficient time to adapt the network. Bitcoin’s open-source structure allows upgrades, including the possible introduction of quantum-resistant cryptographic signatures through future software updates.

Limited Market Impact Expected Even in a highly positive scenario for quantum technology, analysts say only a small number of older coins could be exposed quickly enough to influence market liquidity. Any broader impact would likely unfold gradually, giving investors and wallet holders time to move funds to more secure address formats.

Gradual Upgrades Seen as the Best Approach CoinShares warns that aggressive or premature protocol changes could create new risks, including software bugs or unnecessary network disruptions. Instead, the firm suggests a gradual transition toward quantum-resistant technologies as research matures, allowing Bitcoin to evolve without compromising stability.

Long-Term Challenge, Not a Crisis For investors, the main takeaway is that quantum computing represents a long-term technological consideration rather than an immediate security emergency. With the ability to upgrade cryptography and migrate funds over time, Bitcoin’s architecture is designed to adapt to new threats, reinforcing the view that the quantum risk, while real, remains manageable for the foreseeable future.
