BCH (Bitcoin Cash) Quantum Risk for Holders
Verdict
BCH is only as quantum-safe as the keys and venues that control it. Bitcoin Cash is not quantum-proof. It shares Bitcoin-family classical signature assumptions for spends.
Overview
BCH is the primary liquid asset associated with Bitcoin Cash in market-cap rankings. Holder risk is dominated by authorization keys and custody—not by slogans.
Bitcoin Cash is a UTXO chain forked from Bitcoin’s family of scripts and ECDSA authorization. Quantum risk to exposed public keys follows that classical model.
