🕵️ Which coins are currently exposed to quantum risk at rest?
In our latest research, we quantify Bitcoin’s exposed supply and separate exposure into two categories:
• Structural exposure: 1.92M BTC (9.6%) coins exposed by design
• Operational exposure: 4.12M BTC (20.6%) linked to wallet behavior, address reuse, and custody practices.
The larger share is operational, suggesting that part of Bitcoin’s visible exposure may still be reduced through improved wallet and custody management.
Exchange-related balances alone account for 1.63M BTC (8.1% of issued supply).
