Bitcoin’s 7 million coin quantum problem just reached the US Treasury

CryptoSlate reports the US Treasury has been briefed on a "quantum problem" affecting roughly 7 million BTC sitting in addresses that expose public keys and could be vulnerable if a large-scale quantum computer capable of breaking ECDSA materializes. The Treasury’s engagement indicates authorities view the cryptographic risk as a potential systemic concern for financial stability and law enforcement. For Bitcoin, the key implication is that a real quantum break would enable theft of those coins, likely triggering market shock, accelerating wallet/key migration to quantum-resistant schemes, and prompting regulatory and protocol responses to mitigate contagion.
