According to @deanmlittle on Twitter, Satoshi Nakamoto's original Bitcoin holdings are locked in Pay-to-PubKey (P2PK) addresses, not Pay-to-PubKey-Hash (P2PKH), which leaves them completely unprotected against Shor’s algorithm and potential quantum attacks (source: https://twitter.com/deanmlittle/status/1920477775531593867). For active traders, this highlights a significant security risk for early Bitcoin addresses if quantum computing becomes practical, potentially impacting long-term confidence in Bitcoin’s immutability and influencing market volatility. Monitoring developments in quantum-resistant cryptography is now critical for crypto market participants.
