According to BlockBeats, on June 28, the fund flow situation of Bitcoin Exchange Traded Funds (ETFs) in the United States was reported as follows:

The Grayscale Bitcoin Trust (GBTC) saw a net outflow of $11.4 million. On the other hand, Bitcoin ETFs BITB, ARKB, and EZBC experienced net inflows. BITB had a net inflow of $8 million, ARKB had a net inflow of $1.8 million, and EZBC had a net inflow of $3.6 million.

These figures indicate a mixed trend in the fund flow of Bitcoin ETFs in the US. While GBTC experienced a net outflow, BITB, ARKB, and EZBC saw an increase in their funds. This suggests that investors' interest and confidence in Bitcoin ETFs vary across different funds. The reasons behind these trends could be numerous, ranging from the performance of the funds, market conditions, to investors' perception of the future of Bitcoin.

It is important to note that these figures are based on the data reported on June 28. The fund flow situation of Bitcoin ETFs can change rapidly due to the volatile nature of the cryptocurrency market. Therefore, investors are advised to keep a close watch on the market trends and make informed decisions.
