Coinbase’s David Duong Warns of Quantum Threat to Bitcoin

Coinbase’s Global Head of Investment Research, David Duong, recently highlighted concerns over Bitcoin’s security due to the rapid advancements in quantum computing, as per a January 6th report.

Quantum computing poses risks to Bitcoin by potentially undermining its cryptographic defenses, creating vulnerabilities in the market for nearly one-third of Bitcoin’s supply.

Duong Highlights Quantum Risks to Encrypted Bitcoin Wallets

David Duong, Coinbase’s Global Head of Investment Research, recently cautioned that Bitcoin’s security faces heightened risks due to advancements in quantum computing. His warning, shared via a LinkedIn post, suggests a shift from theoretical concerns to real threats. “Bitcoin’s long-term security may be entering a new regime as quantum computing advances,” Duong noted source.

One-third of Bitcoin supply is housed in wallets using exposed encrypted outputs, making them targets for quantum computing attacks. While quantum computing is in early stages, potential economic impacts are significant if mining efficiencies are affected.

The community’s reaction remains uncertain as discussions on social media are largely absent. Experts emphasize that the main concern lies with signature security, rather than mining efficiency, given current technological constraints.

Bitcoin’s Market Stability Amid Quantum Computing Advances

Did you know? BlackRock identified quantum computing as a threat in its iShares Bitcoin Trust documents last year, highlighting early awareness of potential risks in traditional financial sectors.

As of January 6, 2026, Bitcoin (BTC) trades at $93,823.39 with a market cap of 1.87 trillion. Over 24 hours, trading volume reached $45.49 billion, and price rose 0.88%. In 90 days, Bitcoin has seen a decline of 23.62%, as per CoinMarketCap.

Coincu research notes that rapid progression in quantum computing could prompt financial players to reevaluate Bitcoin’s cryptographic resilience. Though quantum mining seems distant, the highlighted signature vulnerabilities require immediate attention.
