Quantum computing means no password in the world will be safe. It will be able to brute force and crack passwords for almost anything. Bitcoin will be the least of your worries when someone breaks into government accounts and steals all the money in the world. Bitcoin is such a small piece of the world's money for now.
Stop spreading fear and anxiety. Quantum computers might not come in our lifetime.
Completely agree with this. No financial system will be safe (wall street or banks) based on current technology usage. The military wouldn't be safe.
