According to CoinMeta, US spot Bitcoin ETF recorded a net inflow of $142 million at the start of September, bringing positive signals to Bitcoin traders. This inflow indicates that despite market volatility at the end of August, the demand for regulated Bitcoin remains active. ETF inflows have become a clear indicator of demand for Bitcoin in traditional markets, and the positive start in September has provided new focus for the market. Although a single-day inflow does not mean that demand will continue, it shows that the narrative of outflows has not immediately turned into a deeper trend.
