IBIT ETF risk disclosure highlights emerging threat to blockchain cryptography amid record-breaking inflowsBlackRock, the world’s largest asset manager, has officially flagged quantum computing as a potential risk to Bitcoin’s cryptographic integrity in a new update to its iShares Bitcoin Trust (IBIT) regulatory filing.
