[Analyst: Bitcoin ETF sees net outflows, short-term market volatility risk rises] Deep Tide TechFlow reports that on September 14, analyst Darkfost stated that after three consecutive weeks of positive fund inflows supporting the recent rally, Bitcoin ETFs have shown weakened momentum this week, with an outflow of nearly 6,000 BTC. Current spot demand remains weak, and if ETF demand continues to decline, it may become more challenging for Bitcoin to maintain its current price range. Market volatility may intensify in the coming week, and changes in fund flows should be closely monitored.
