Overview
BlackRock has filed for the iShares Bitcoin Managed Protection ETF, a proposed product that would use options linked to IBIT to limit losses while capping some upside. The filing coincided with strong demand for BlackRock’s existing IBIT, which led US spot Bitcoin ETF inflows despite outflows from Fidelity and Grayscale.
