Final point I’ll raise that I think is impotent to consider - in practice Bitcoin wallets don’t adopt new features basically ever. Even if we ship PQC support tomorrow in every possible form, I’m willing to bet there will still be popular wallets out there not using it in a decade or two. If a CRQC is a material risk then (quite possible!) then the analysis in the previous post isn’t just a weird hypothetical, it’s reality!
