Clock is ticking for bitcoin to prevent quantum threat as it could drain 6.9 million BTC including Satoshi’s

Bitcoin's ownership is at risk from quantum computers due to the vulnerability of its private key cryptography, unlike its hashing which is quantum-resistant. A quantum algorithm called Shor's can collapse the time needed to derive private keys from public keys, which are already exposed for approximately 6.9 million BTC on the blockchain, including early holdings by Satoshi Nakamoto. While Ethereum has a formal quantum-resistant program, Bitcoin lacks a concrete strategy, with proposals like BIP-360 facing challenges in gaining broad developer support. The decentralized and change-averse nature of Bitcoin's governance makes coordinating a large-scale cryptographic migration significantly more difficult than for Ethereum, raising concerns about its ability to adapt before quantum hardware matures.
