Coinbase urges Bitcoin to begin post-quantum migration now

Coinbase published priorities for Bitcoin's post-quantum transition, urging early preparation for signature upgrades and fund migration. The exchange, which CoinDesk says holds 5% of all bitcoin, called for flexible addresses, a backup quantum-proof key and a separate debate over lost coins, arguing the multi-year migration must begin before any "Q-Day."
