Updated: Jan 06 2026- Security Risk Warning: David Duong, Coinbase's Global Head of Investment Research, highlighted that Bitcoin's cryptographic security is under severe threat due to rapid advancements in quantum computing, potentially exposing nearly one-third of Bitcoin's supply to market vulnerabilities.
- Wallet Vulnerabilities: Approximately one-third of Bitcoin is stored in wallets utilizing exposed encrypted outputs, making them prime targets for quantum computing attacks, which could jeopardize Bitcoin's long-term security.
- Uncertain Market Reaction: Despite quantum computing being in its early stages, the community's response to this risk remains unclear, with a noticeable lack of discussions on social media, indicating insufficient market awareness of security issues.
- Potential Economic Impact: Although quantum mining seems distant, experts emphasize that signature security is the primary concern under current technological constraints, and failure to address these vulnerabilities could significantly impact Bitcoin's market stability.
