Spot BTC ETF flows are a pure indicator of market sentiment, says analyst

Inflow and outflow data from U.S. spot Bitcoin ETFs serve as a pure indicator of market sentiment, according to Bloomberg ETF analyst James Seyffart. He explained that unlike assets under management (AUM), which can be distorted by price fluctuations, net flow figures track the actual movement of BTC into and out of the funds. This, Seyffart noted, makes them a direct measure of market activity.
