BlackRock attracts $5B as investors swap physical BTC for IBIT shares
BlackRock's iShares Bitcoin Trust (IBIT) has seen $5B in physical BTC swaps for its ETF shares, driven by concerns over custody failures and security risks. The minimum swap amount was reduced by 96% to $1M, expanding access. In August, IBIT attracted $200M in weekly inflows, half of the total weekly net inflows. According to BlackRock, this reflects a custody migration rather than increased BTC demand.
