[Glassnode: Institutional Bitcoin Buying Interest Cools Down, Spot ETF 7-Day Average Net Inflows Turn Negative] BlockBeats News, March 31, Glassnode released an analysis stating that the 7-day simple moving average net inflow (7D-SMA) of U.S. spot Bitcoin ETFs turned negative starting early last week, with recent daily net outflows of 200 to 500 BTC. Although the outflow scale is not significant, it has been persistent, which is a relatively subtle signal indicating that at the current Bitcoin price level, institutional buying interest and confidence in demand remain hesitant.
