Europol Warns Crypto Wallets Are ‘Primary Risk’ for Quantum Attacks

Europol naming wallets rather than chains as the weak point shifts the quantum conversation from abstract cryptography to custody, where the practical exposure sits for anyone holding keys. The absence of a timeline or named networks cuts both ways: it keeps the warning credible as a risk assessment rather than a forecast, but leaves the real question open — whether wallet-level migration happens fast enough, and who bears the cost of moving coins off vulnerable addresses. The second report's harvest-now, decrypt-later angle is the quieter concern, since it implies exposure that predates any future upgrade.
