About 35.4% of the BTC supply—7.12 million coins—has public keys exposed on-chain; in May, the figure was 30.2%.
According to Glassnode, address reuse accounts for 25.8%. About 11.6% attributed to exchanges is already included in the reused-address figure, so the two figures should not be added together. This is a snapshot of the existing supply, not a countdown to theft. For ordinary users, stop reusing the same address. Moving funds from reused addresses to new ones can reduce this exposure, though early P2PK outputs can’t be migrated so easily.
What this means for you: what you can control is your own address habits—not betting on when quantum computing will arrive. If the share of exposed coins later falls, the alarmist narrative may cool down; if address reuse keeps rising, dismissing it as just a statistic won’t be enough. Would you first check whether you’ve reused any addresses, or treat this as a long-term risk for now?
