Why bitcoin held up despite quantum computing fears, Bernstein says risk already priced in

Bernstein said the bitcoin market has already priced in a range of risks, including quantum-security worries, pointing to a roughly 50 percent fall from its October 2025 record high. The view follows recent Google research suggesting future quantum computers could break elliptic-curve cryptography in some blockchain designs. Bernstein said Bitcoin Core developers still have time to choose a post-quantum upgrade path. Others said the main challenge is social adoption, including moving users to new standards.
