Jefferies' Wood drops 10% bitcoin allocation over quantum computing fears - The Block

Jefferies’ veteran strategist Christopher Wood reduced his recommended bitcoin allocation from 10% to 5% in January 2026, citing emerging threats from quantum computing advancements. The decision reflects growing concerns that quantum computers could eventually break bitcoin’s cryptographic security, undermining its long-term viability as a store of value. Wood’s move signals a shift in institutional sentiment, as quantum progress by tech giants and startups accelerates, potentially rendering current encryption obsolete within a decade. The adjustment follows warnings from cybersecurity experts that post-quantum cryptography standards must be adopted urgently to protect blockchain networks from future attacks. This strategic pivot underscores the intersection of quantum computing and crypto markets, forcing investors to reassess risk exposure amid rapid technological disruption.
