35.4% of Bitcoin Supply Has Exposed Public Keys, Glassnode Says Could Be Targets for Quantum Computer Attacks

Odaily reports: Glassnode posted on X that approximately 35.4% of the Bitcoin supply, or 7.12 million BTC, has its public keys visible on-chain, potentially making it a target for future quantum computer attacks. Among this, address reuse accounts for 25.8%, and exchange holdings account for 11.6%. This exposure ratio has continued to rise from 24.8% in early 2021. Glassnode noted that transferring the relevant tokens to new addresses would eliminate this exposure risk.
