Monday ETF inflows led by FBTC, continuing positive streak

Spot Bitcoin ETF flows remained positive on March 21 and March 24, marking seven straight days of inflows after a rocky start to the month.

On March 21, the standout performer was iBIT, which attracted a solid $105 million in new capital—its second-largest single-day intake that week. In contrast, BTCW recorded a notable outflow of $21.9 million, marking the only negative figure among the ETFs that day. All other ETFs—including FBTC, BITB, ARKB, BTCO, EZBC, BRRR, HODL, GBTC, and BTC—saw no change on March 21. Overall, the day ended with net inflows of $83.1 million.

On March 24, FBTC led the pack with an $82.9 million inflow, followed by BITB ($19.2 million) and IBIT ($18.1 million). ARKB, however, saw an outflow of $41 million, dampening the total somewhat, while BTCW added a modest $5 million. As with March 21, the other ETFs stayed flat, leaving March 24’s net inflow at $84.2 million.

Last week, the market saw consistently strong inflows into iBIT—topping $218 million on March 18 alone—punctuated by occasional outflows from ARKB and BTCW. By March 21, the overall weekly picture was still decidedly positive, culminating in the $83.1 million net total for that day. Against this backdrop, March 24’s $84.2 million inflow continues the prevailing bullish momentum.
