BlackRock seeks to shield bitcoin investors from losses after rival fund weathers 50% crash

While bitcoin BTC $82 687,80 lost more than half its value in the past year's selloff, investors in one Calamos Investments’ fund were spared much of the pain. The Naperville, Illinois-based firm's Bitcoin Structured Alt Protection ETF – October (CBOO) dropped just 1% since the start of its one-year protection period in October 2025, according to a Calamos spokesperson. The largest cryptocurrency, in contrast, tumbled as much as 52% from its record high of roughly $126,000. Now BlackRock (BLK), the world's largest asset manager, wants to offer investors a similar way to protect themselves from bitcoin's price swings. On Monday, the firm filed to introduce the iShares Bitcoin Managed Protect ETF, which would give investors exposure to bitcoin's gains while seeking to limit losses when the cryptocurrency falls.
