Up to 7M BTC in wallets face quantum computing risk as public keys are exposed on-chain.

A Coinbase report reveals that between 6.9 and 7 million Bitcoin, about a third of all Bitcoin, are stored in wallets with public keys visible on the blockchain, making them vulnerable to future quantum computing attacks. While Bitcoin's mining and hash functions remain quantum-resistant, wallet-level digital signatures are at risk, especially in legacy and reused addresses. The report highlights a governance challenge since many vulnerable coins, particularly 1.7 million BTC in lost or inactive wallets, cannot be moved to safer formats. The council suggests proactive measures like migration deadlines and freezing vulnerable funds, but these require broad consensus in the Bitcoin community. For most modern wallet users, the immediate risk is low, but the issue demands early governance action to protect assets before quantum threats become practical.
