CoinMeta data: Blackstone Group has submitted an application to the U.S. Securities and Exchange Commission for the management and protection of iShares Bitcoin. This is Blackstone's third Bitcoin-related application, aimed at limiting potential losses and gains by using options. The fund will utilize options related to Blackstone's iShares Bitcoin Trust ETF ( IBIT ), rather than directly holding Bitcoin.
