Glassnode: 35.4% of Bitcoin supply public keys have been exposed, potentially becoming targets for quantum computer attacks

According to the latest data from Glassnode, approximately 35.4% of the Bitcoin supply (7.12 million BTC) public keys are visible on-chain, which is part of what future quantum computers may attack.

Among them, address reuse accounts for 25.8%, and exchanges account for 11.6%. The exposure ratio has continued to rise from 24.8% at the beginning of 2021, and the risk exposure under the threat of quantum computing is expanding. Glassnode points out that transferring these tokens to new addresses can eliminate this exposure risk.
