Bitcoin ETF News: BlackRock Wants to Launch a Bitcoin Fund That Limits Your Losses. What’s the Catch?
BlackRock (BLK) filed for the iShares Bitcoin Managed Protect ETF (PBIT), a buffer ETF designed to limit losses for Bitcoin investors, with a trade-off of capping gains. PBIT aims to protect against losses from the iShares Bitcoin Trust ETF (IBIT), which manages over $65 billion in assets. Bitcoin (BTC) is currently trading at about $81,511, down 26.3% over the past year. Details on PBIT's protection level, cap, fees, and launch date are pending.
