According to BlockBeats, data from Farside Investors on June 15 reveals that Bitcoin spot ETFs in the United States have experienced a net outflow of $580.6 million this week. The Grayscale Bitcoin Trust (GBTC) accounted for a significant portion of this outflow, with a net outflow of $274 million. On the other hand, BlackRock's iShares Bitcoin Trust (IBIT) saw a net inflow of $41.6 million.

This data indicates a shift in investor sentiment towards Bitcoin ETFs, with more investors pulling out than investing in these funds. The significant outflow from GBTC suggests that investors are moving their funds elsewhere, possibly due to market volatility or changing investment strategies. However, the net inflow into BlackRock's IBIT indicates that some investors still see potential in Bitcoin ETFs.

It's important to note that these figures represent the net movement of funds, not the total amount invested or withdrawn. The net outflow or inflow is calculated by subtracting the amount of money withdrawn from the amount of money invested. Therefore, even though there was a net outflow, it does not necessarily mean that all investors are pulling out of Bitcoin ETFs. Some are still investing, as evidenced by the net inflow into BlackRock's IBIT.
