U.S. spot Bitcoin ETFs recorded ~$236.5M in net outflows on September 1, with only three of thirteen funds reporting and $IBIT accounting for ~$201.2M of the total. Bitcoin trades at $77643.95 inside its Bollinger Bands with upper resistance at $79159.2 and lower support at $77167.25 while the EMA50 at $77573.84 acts as immediate long-term support above the EMA200 at $71685.56. The MACD death cross at -188.64 signals short-term bearish momentum even as RSI at 44.36 remains neutral, suggesting price may retest the 50-EMA before any continuation higher. This early-month redemption wave arrives against a backdrop of sustained institutional positioning in spot products over the past six months and directly influences BTC price prediction models as well as broader crypto market crash scenarios. Analysts tracking Bitcoin ETF outflows note the data could pressure near-term flows into related vehicles.
