The inflows and outflows of the BTC ETF are quite insightful—this wave in September came in strong and left just as quickly. On September 21st, there was a single-day inflow of nearly $1 billion, the largest single-day inflow in almost a year. After that, it decreased every trading day, and by the 30th, it was already in a net outflow state, with BTC's price also moving sideways. Basically, this pump was driven by institutions/Americans, but now the big players have finished buying and are taking a break. So, who's going to take over next?
