Spot Bitcoin ETF Weekly Outflows Surge Again
U.S.-listed spot Bitcoin exchange-traded funds recorded their largest weekly outflows since late June. The 13 funds recorded a combined $389.7 million in net outflows during the week of August 10, according to Bloomberg data. This followed $853.5 million in net inflows during the previous week.
Fidelity’s FBTC led redemptions with $153.2 million in outflows, equivalent to approximately 2,438 BTC. GBTC saw $88.3 million in outflows, followed by IBIT at $78.9 million and ARKB at $70.3 million.
The only funds to record inflows were Grayscale Mini BTC, which attracted $76.0 million, and MSBT, with $7.1 million.
The last time spot Bitcoin ETFs saw outflows this severe was during the June 24 flush, when Bitcoin bottomed at $58.4K before buyers returned. If this week’s outflows are larger, the $58.4K level will be the key level to watch for BTC price.
