Europol Says Some Bitcoin Wallets Have No Quantum Fix: Is Yours One of Them?

Europol has warned that some older Bitcoin wallets, particularly those using exposed public keys or address formats that cannot be upgraded, may be vulnerable to future quantum attacks. The threat is not considered immediate: practical quantum computers capable of breaking Bitcoin’s cryptography do not currently exist. The key risk is that certain coins may be difficult or impossible to move to quantum-resistant addresses if the technology advances. Bitcoin holders should identify whether their funds use vulnerable address types and follow credible guidance on future migration options.
