There’s a lot of FUD around Bitcoin’s quantum risk. The fact is that Bitcoin’s security is anchored in hash-based proof-of-work, which remains quantum-resistant (Grover only yields a quadratic speed-up). The main quantum target (ECDSA public keys) is already mitigated by non-reuse of addresses and can be upgraded to post-quantum signatures (eg.: NIST FIPS-205 hash-based schemes). Bitcoin’s architecture is adaptable, conservative and mathematically robust. Quantum doesn’t break Bitcoin. https://csrc.nist.gov/pubs/fips/205/final(Gabor Gurbacs)
