Bitcoin has 3–5 years to prepare for quantum risk, says Bernstein

Bernstein analysts warn of a future quantum threat to Bitcoin, but believe the risks are concentrated in older wallets and exposed keys, and are unlikely to cause existential disruption, giving Bitcoin a 3-5 year preparation window. This assessment may alleviate short-term concerns but highlights a long-term risk. The news may have a neutral impact on Bitcoin's price in the short term, as the threat is perceived as manageable and distant.
