What was the chances to crack a private key? Like 1 in some billion? How is that hard for quantum computer to do? Perhaps it's already possible but they are not letting out pandora's box yet.
its one in some 2^256 give or take some bits (maybe its actually 128). But I bet mathematics will catch up and solve reverse EC without having to brute force it, and also all your computers and devices will be bugged by hackers and the government, cameras, drones, and EMF fields, or they will just be able to read your key via teleportation, or the police could just torture it out of you the old fashioned way.
