【Quantum risk】The latest data from Glassnode shows that the public keys of approximately 7.12 million BTC (35.4% of the supply) have been exposed on-chain and could theoretically become targets of attack if quantum computers mature in the future. Address reuse accounts for 25.8%, while exchange holdings account for 11.6%. This proportion has risen steadily from 24.8% in early 2021 to 31.2% in October, and has now reached a record high. Note: No quantum computer capable of breaking Bitcoin’s encryption currently exists, and the risk remains theoretical and long-term. A Glassnode co-founder pointed out that moving coins to brand-new addresses can eliminate the exposure caused by address reuse. (Source: Glassnode / Crypto Briefing, data as of November 10)
