BlackRock’s IBIT recorded roughly $665 million in net inflows on October 19, according to the excerpt, more than offsetting withdrawals from other US spot Bitcoin ETFs. Fidelity’s FBTC had roughly $83.6 million in outflows, while Grayscale’s GBTC had about $54.9 million.
The figures show ETF subscriptions and redemptions, not how much new cash bought Bitcoin at a particular hour. A single day’s flows also cannot establish why individual institutions moved money.
