More than one in three Bitcoins—with a total value exceeding $500 billion—are now at risk from future quantum computers.
Data from Glassnode shows that 7.12 million BTC, or 35.4% of the total supply, have public keys that are already visible on the blockchain.
Most Bitcoin addresses reveal their public key the first time funds are sent from them.
Any coins remaining at such an address, or sent to it subsequently, are considered vulnerable.
"Moving these coins to a new address eliminates this vulnerability," notes Glassnode.
