BlackRock seeks to shield bitcoin (BTC) investors from losses after Calamos fund weathers 50% crash

BlackRock filed for a bitcoin-linked ETF aiming to limit losses while allowing gains. Calamos' similar ETF lost just 1% as bitcoin dropped 52% from its peak. BlackRock's proposed fund builds on its iShares Bitcoin Trust (IBIT), which manages over $65 billion. Calamos' funds use U.S. Treasuries and bitcoin options to cap losses.
