Coinbase Calls for Early Bitcoin Migration to Quantum Security

Coinbase is urging the Bitcoin community to begin preparing for post-quantum cryptography, warning that quantum computing could eventually threaten the network's security. The exchange's call comes as key questions around quantum-resistant designs, migration rules, and the treatment of legacy coins remain unresolved. For traders, the story is a long-term technical and governance issue rather than an immediate price catalyst, though it highlights a potential future risk to Bitcoin's security narrative.
