BlackRock buys $1B of Bitcoin over past 20 days as Grayscale bleeds another $255M

BlackRock's iShares Bitcoin Trust (IBIT) saw $1.08B inflows over 20 days, while Grayscale's Bitcoin Trust (GBTC) had $254.7M outflows. IBIT now holds 785,000 BTC with $60B AUM, while GBTC holds 130,000 BTC with $10B AUM. IBIT's lower fees (0.25% vs. GBTC's 1.5%) drive the shift, with US spot Bitcoin ETFs holding 6% of Bitcoin's total supply.
