Bitcoin exchanges can reduce quantum exposure before a network upgrade

Bitcoin exchanges can reduce their quantum-related exposure before any protocol upgrade by moving funds from reused or publicly exposed addresses into fresh, quantum-resistant address types. This is a precautionary measure against future quantum computers potentially deriving private keys from exposed public keys, rather than an indication of an immediate threat. Exchanges’ ability to consolidate and migrate funds proactively could limit systemic risk while the Bitcoin ecosystem develops and coordinates a longer-term upgrade.
