The relationship between Bitcoin price and ETF fund inflows shows a notable short-term reaction. Studies indicate that significant ETF inflows often correlate with Bitcoin price increases, as inflows reflect heightened investor demand. For instance, a $3 billion net inflow can lead to a $9,300 price surge. However, the impact is not always immediate or consistent, as market dynamics and macroeconomic factors can dilute the effect. Outflows, often triggered by negative sentiment or high fees, may depress prices temporarily. While inflows generally signal bullish trends, short-term price reactions can vary due to external factors like regulatory news or market volatility.
