US Bitcoin spot ETFs experienced a significant net outflow of $812.27 million (1.1288 trillion KRW) on the 1st, marking the largest such outflow in five months, according to Trader T. This substantial movement signals potential shifts in investor sentiment towards Bitcoin ETFs. Fidelity's FBTC led the outflows with $331 million, followed by Ark Invest's ARKB at $328 million. Grayscale's GBTC saw $66.79 million exit, while Bitwise's BITB experienced a $38.27 million outflow. Smaller outflows were recorded across other ETFs, including Grayscale Mini BTC ($33.60 million), Franklin Templeton's EZBC ($6.57 million), Invesco's BTCO ($5.08 million), and even BlackRock's IBIT ($2.61 million). Notably, no Bitcoin spot ETFs registered net inflows on this day. This widespread outflow warrants close monitoring to determine if it represents a short-term correction or a more sustained trend impacting the broader crypto market. ```
