Bitcoin's signature scheme is cryptographically broken by quantum computers. The article frames this as a compound probability: chance a CRQC appears by time T, multiplied by chance Bitcoin fails to upgrade by then. Google targets PQC migration by 2029; one quantum researcher assigned ~10% odds to CRQC existence by 2030. Success requires both soft fork consensus and ecosystem-wide wallet/exchange adoption.

Bitcoin and Quantum Computing
Google targets quantum-resistant cryptography by 2029 while researchers assign 10% odds to cryptographically-relevant quantum computers by 2030—Bitcoin's survival hinges on a coordinated soft fork and ecosystem-wide wallet adoption before that window closes.

A quantum threat to Bitcoin has some asking the unthinkable: Is it time to freeze old wallets belonging to Satoshi Nakamoto?
Quantum advances threaten 6.9M vulnerable Bitcoin coins, forcing the community to choose between mandatory BIP360 hard fork and freezing Satoshi's estimated 1.1M BTC holdings.
