Post-quantum Bitcoin wallets launch as experts debate real security benefits versus fear-driven costs

Post-quantum Bitcoin wallets are already being marketed even though large-scale quantum computers capable of breaking Bitcoin's cryptography do not yet exist. Some security specialists describe these products as a potential fear tax, while wallet providers claim they offer long-term insurance and proactive protection against harvest-now-decrypt-later attacks. With Bitcoin still below its October 2025 peak, the debate over protocol-level upgrades versus wallet-level defenses is adding to wider concerns about quantum risk and institutional adoption.
