Can Quantum Computers Crack Bitcoin? CoinShares Says Not For A Decade

CoinShares says quantum computers are unlikely to pose a practical threat to Bitcoin for at least another decade. The assessment addresses concerns that future quantum advances could crack Bitcoin’s cryptography.

Key Takeaways

  • 01 CoinShares estimates Bitcoin is not likely to face a quantum-computing threat for at least 10 years.
  • 02 The discussion centers on whether quantum computers could break Bitcoin’s cryptographic protections.
  • 03 The claim is an outlook from CoinShares, not confirmation that quantum risk has been eliminated.

Bitcoin (BTC) faces no immediate threat from quantum computing, as breaking its cryptographic security remains at least a decade away, according to a report published by CoinShares.

What Happened: Quantum Timeline

The digital asset investment firm concluded quantum computers capable of compromising Bitcoin's security are "nowhere near dangerous territory."

Breaking the secp256k1 encryption standard would require quantum systems with millions of logical qubits, far exceeding current capabilities, the report stated.

Reversing a public key within one day would require an attacker to operate a fault-tolerant quantum computer with 13 million physical qubits, approximately 100,000 times more powerful than today's largest quantum systems, according to researchers cited in the report. Breaking it within an hour would demand performance 3 million times better than current quantum computers, CoinShares noted.

Why It Matters: Built-in Protection

Modern Bitcoin addresses keep public keys hidden behind hashes until coins are spent, creating an exponential layer of protection.

The firm characterized quantum technology as a foreseeable engineering challenge with sufficient time for defensive upgrades, rather than an immediate threat to the network's 21 million supply cap or proof-of-work mechanism.

"For institutional investors, the key insight is that quantum risks are contained, with an extended timeline for resolution," CoinShares stated. "Bitcoin's architecture provides built-in resilience, enabling proactive adaptations."

According to Grayscale's updated outlook on digital assets, Bitcoin faces no immediate price threat from quantum computing in 2026, The investment firm's latest research acknowledges the theoretical risk but dismisses its near-term market impact based on current technology timelines.
