If Quantum Computing is released into the wild and starts to attack bitcoin , what measures would we see to mitigate these attacks?
Hope some miners can also get a quantum computer to compete with mining and switch to an algorithm for the keys that would take the QC longer than it's expected Quantum decoherence time by a factor of billions upon billions.
What if the government controls the Quantum computer , and there isn't anyone to fight back? Would that spell the end of Bitcoin? And if there is , would it be necessary to move to QC resistant cryptography?
