Address Reuse Warnings Spotlight 4M Bitcoin Addresses as Price Holds Near $62K

Bitcoin address reuse warnings have renewed focus on long-term quantum exposure risks for roughly 7 million BTC. The story began with early June quantum chip breakthroughs from Microsoft and Google plus Tim Draper’s repeated claims that banks face greater threats than Bitcoin. It escalated on June 11-13 when Coinbase’s Quantum Advisory Council released its report flagging 1.7 million legacy P2PK coins and up to 5 million BTC exposed via address reuse, urging immediate post-quantum migration planning via BIP-360. Latest coverage on June 15 highlights exchange cold wallets and institutional custody as key pressure points while BTC trades near $62,629 with no immediate price impact.
