According to BlockBeats, data from Farside Investors revealed on April 17th that the Grayscale Bitcoin Trust (GBTC) and the ARK Blockchain Technology ETF (ARKB) experienced substantial net outflows. Specifically, GBTC saw a net outflow of $79.4 million, while ARKB had a net outflow of $12.9 million.

The data for BlackRock's iShares Bitcoin ETF (IBIT) and Fidelity's Bitcoin ETF (FBTC) have not yet been released. However, the net outflow situation for GBTC has slightly eased compared to the previous few days.

These outflows represent a significant shift in investor sentiment, potentially indicating a decrease in demand for these particular investment products. The reasons behind these outflows are not clear, but they could be due to a variety of factors, including market volatility, changes in investor risk appetite, or shifts in the broader economic landscape.

It is important to note that these figures are subject to change as more data becomes available. Investors and market observers should continue to monitor these developments closely.
