Bitcoin be zero before 2030s! forked to multiple quantum-resistant chains, lead to collapse of consensus, as per White House NSM10 have called whole-of-state for migration to PQC quantum secure. but all digital signature algos, even in future 20 years, are bigger sizes in either pubkey or signature
