Trump\'s quantum push renews bitcoin security fears over 7 million BTC exposure

The United States is bringing forward to 2031 a federal deadline to shift to quantum-resistant cryptography and is pushing quantum computer development as a national task, reviving concerns about bitcoin security. About 7 million bitcoins with already exposed public keys are seen as potential targets for future quantum computers, with more than 70 percent linked to repeated address use. Some analysts say the near-term threat remains limited, but the pace of migration is a key challenge.
