Coinbase says Bitcoin should begin preparing for a potential future quantum threat before cryptographically relevant machines arrive. The exchange is pushing for flexible post quantum signatures, staged adoption and a separate debate over dormant or late migrating wallets.

Europol has warned that cryptocurrency wallets with exposed public keys are the main area of concern as quantum computing advances. The agency urged a phased industry shift toward post quantum protections before vulnerable wallets become targets.

Bitcoin and Ethereum are moving post-quantum planning into sharper focus as U.S. support for quantum hardware expands. Developers are not treating the threat as immediate, but migration timelines are increasingly clustering around a 2029 planning horizon.
