Similar to March 21, other ETFs remained unchanged, resulting in a net inflow of $84.2 million for March 24.
Throughout the previous week, iBIT consistently attracted strong inflows—reaching $218 million on March 18 alone—interrupted by intermittent outflows from ARKB and BTCW. By March 21, the overall weekly trend remained heavily positive, culminating in a net total of $83.1 million for that day. In this context, the $84.2 million inflow on March 24 continues to reflect the prevailing bullish sentiment.
