U.S. spot Bitcoin exchange-traded funds recorded approximately $307.46 million in net inflows on Aug. 21, extending a consecutive daily inflow streak to five trading days. BlackRock’s IBIT led with $239.28 million, or nearly 78% of the total, followed by Fidelity’s FBTC at $30.19 million, Grayscale Mini BTC at $13.62 million, Bitwise’s BITB at $9.21 million, Morgan Stanley’s MSBT at $7.73 million, VanEck’s HODL at $4.36 million, and Ark Invest’s ARKB at $3.07 million. The sustained buying coincides with a broader recovery in digital asset markets and Bitcoin trading above key support levels, underscoring continued institutional demand for regulated exposure after earlier summer volatility.
