Quantum computers, though still in development, could eventually become powerful enough to break current encryption methods, posing a long-term security concern for digital assets.
IBIT, with roughly $64 billion in net assets, is the largest spot Bitcoin ETF.
Despite the warning, Bloomberg Intelligence’s James Seyffart emphasized that such disclosures are routine and meant to outline any conceivable risk to investors.
