Quantum Computing Threat to Bitcoin: Only 10K Coins at Risk, Takes Millennium to Attack, Says CoinShares

A recent CoinShares report suggests that while a small fraction of Bitcoin, specifically under 10,000 coins held in smaller wallets, faces theoretical quantum computing vulnerability, the practical risk remains negligible. The analysis indicates it could take up to a millennium to compromise a single vulnerable wallet with current hypothetical quantum technology, far outweighing the potential gains and justifying the immense cost of such an attack. The report contextualizes the threat, emphasizing that the state of quantum computing is nascent and the Bitcoin network's security is robust. It highlights that addresses that haven't spent funds are less susceptible, and the community is actively researching quantum-resistant cryptography. While the findings serve as a reminder for future technological shifts, they do not represent an imminent danger to the vast majority of Bitcoin holdings, providing reassurance to investors about the network's current security.
