Coinbase analyst warns quantum computing could disrupt Bitcoin security and mining model

Coinbase head of investment research David Duong stated on Monday that quantum computing threatens not only Bitcoin's wallet-level cryptography but also its wider economic and security model. He argued that quantum machines capable of running Shor's and Grover's algorithms could undermine ECDSA-based signatures and SHA-256 mining, even as sceptics such as Adam Back maintain that such risks remain decades away.
