The U.S. Bitcoin (BTC) spot exchange-traded fund (ETF) witnessed a significant outflow of $287 million on the previous trading day, according to data from TraderT. These outflows indicate a bearish sentiment among investors, as they are reducing their exposure to BTC spot ETFs. Individual funds also experienced varying levels of inflows and outflows. BlackRock's iShares Blockchain and Tech ETF (IBIT) saw a positive inflow of $79.4 million, while Grayscale's Bitcoin Trust (GBTC) recorded a modest inflow of $3.75 million. However, the outflows were more pronounced in other funds, with Fidelity's Wise Origin Bitcoin Trust (FBTC) facing a significant outflow of $282 million, Bitwise's Bitwise 10 Crypto Index Fund (BITB) experiencing an outflow of $35.98 million, Ark Invest's ARK Next Generation Internet ETF (ARKB) recording an outflow of $112.59 million, and Invesco's Alerian Galaxy Bitcoin ETF (BTCO) seeing an outflow of $14.15 million. These outflows suggest that investors are shifting their funds from these ETFs, potentially due to concerns over market volatility or other factors.
