Bitcoin ETFs reversed course in a day. Who is buying when the funds sell?
U.S. spot Bitcoin ETFs flipped from $524.8 million in net inflows on October 21 to $635.6 million in outflows on October 22, with another $137.9 million withdrawn on October 23. The rapid reversal shows how quickly institutional flows can turn and raises questions about who is absorbing the selling. Traders watch ETF flows as a proxy for institutional demand, so a two-day swing of this size is a caution signal for BTC price momentum.
