The New Scientist account correctly flags the ECDLP vulnerability and Shor’s algorithm but underplays how quickly error-corrected logical qubits are scaling beyond raw physical counts. Google’s 2024 analysis of 500,000 physical qubits assumes ~0.1% error rates per gate; Oratomic’s 10,000-qubit claim implies aggressive error suppression already demonstrated in 2025 trapped-ion experiments. Neither paper models the economic cascade: with roughly 20% of Bitcoin held in retirement vehicles per Fidelity and Grayscale data, a credible Q-Day demonstration would trigger simultaneous wallet migrations and forced liquidations, amplifying volatility far beyond the 2022 FTX event. NIST’s post-quantum standardization process, now in final rounds, shows migration timelines of 5–10 years for legacy systems—yet Bitcoin’s consensus rules require a hard fork with uncertain miner adoption. The coverage also misses that Ethereum’s account abstraction upgrades already embed quantum-resistant signature placeholders, giving it a structural edge over Bitcoin’s simpler script. Retirement accounts locked into cold-storage multisig setups face the steepest risk because private-key rotation demands active management most holders lack.
