Quantum Computing and Bitcoin: Why 'Q-Day' Is Not an Existential Threat
Recent advances in quantum computing raise long-term concerns for Bitcoin's security, but the threat is not immediate. Experts estimate that vulnerable cryptography could be phased out between 2029 and 2035 through protocol upgrades and new cryptographic standards. Migration will require careful coordination, but Bitcoin can adapt without risking instant failure. Overall, quantum risk is a future issue related to governance and timing, not an urgent crisis.
