Bitcoin’s Quantum Risk Limited to 10K Coins

Key Points:
  • CoinShares identifies 10,200 Bitcoin at risk from quantum tech.
  • Vulnerability limited to legacy wallets.
  • Quantum threats expected 10+ more years ahead.

CoinShares reported only about 10,200 Bitcoins are at risk of quantum attacks due to vulnerability in legacy P2PK wallets, according to research published in early 2026.

The report highlights the minimal immediate threat to Bitcoin’s broader stability, yet stresses the importance of adapting to future quantum advancements for ongoing security.

CoinShares’ recent report highlights that approximately 10,200 BTC in legacy wallets are vulnerable to potential quantum attacks. This constitutes a mere 0.05% of the total Bitcoin supply, focusing on exposed public key wallets presenting minimal threat.

Christopher Bendiksen spearheaded the research, suggesting quantum systems need to be significantly more advanced to pose a substantial threat. Key changes included analysis from the perspective of upcoming computational capabilities.

Immediate effects on the market are minimal since only a small fraction of Bitcoin is at risk. Experts claim these findings resemble routine large-scale transactions without causing systemic disruptions in the cryptocurrency ecosystem.

The financial implications indicate only $719 million falls under quantum risk amidst a larger trillions-worth market. Social and political factors seem unaffected since the threat’s immediate reality remains distant, according to leaders in the crypto industry.

Some market movements could stem from cautionary actions by holders of legacy Bitcoin. Analysts foresee no regulatory upheaval as framework readiness for quantum disruption is improbable in the near term.

Looking ahead, the potential outcomes could include updates to cryptographic standards and infrastructure to counteract future technological threats. The emphasis is on preparatory adjustments rather than immediate overhaul of existing Bitcoin networks.
