As per my perspectives, If quantum computers become a threat to Bitcoin, the community might do a "fork" to upgrade to stronger cryptography, making Bitcoin's security even better. They'd make this move based on how quickly quantum tech is advancing, not just after attacks happen. Also, a quantum hacker might test their skills on smaller targets first, keeping their strongest attacks hidden until needed. This plan would help Bitcoin stay safe by improving its security ahead of time. Does it make sense ?
