Bitcoin (BTC) public keys tied to 35.4% of the supply are visible on-chain, placing about 7.12 million BTC in a group that could be targeted by future quantum computers.

The figure describes potential exposure tied to key visibility on the blockchain. It is not a count of coins already taken. The risk scenario involves a future quantum computer capable of attacking the visible keys.

A transfer of affected holdings to fresh addresses removes the exposure. The on-chain measure classifies supply by public-key visibility.
