BlackRock Files for Bitcoin ETF That Trades Capped Gains for a 10% Loss Floor
BlackRock filed for the iShares Bitcoin Managed Protection ETF (PBIT), a fund that caps gains to limit losses. It will use call options on IBIT and similar products, with a 10% loss floor. The fund's fee and launch date are not yet set. BlackRock already offers the iShares Bitcoin Premium Income ETF (BITA), which also limits upside.
