The capital flow of Bitcoin ETFs reflects institutional behavior more clearly than daily price movements, demonstrating strategic asset allocation decisions rather than the urgency of short-term trading. Although capital inflows directly generate demand for BTC, factors such as global market trading volume, gradual expansion of institutions, or macroeconomic environments may prevent immediate price increases. Continuous capital inflow indicates that investors are holding long-term portfolios, and as Bitcoin is transferred to custodial institutions, the supply will tend to tighten. Traders should interpret capital flows in conjunction with derivatives data and view them as medium-term signals. Ongoing institutional accumulation consolidates Bitcoin's maturity, although short-term volatility may occur.
