Recently, the crypto assets market has experienced a wave of intense fluctuations, especially in the ETF sector. The latest data shows that within just two days on September 23, Bitcoin and Ethereum's spot ETFs faced a net outflow of up to $244 million, a phenomenon that industry insiders have dubbed "September Red".

In terms of Bitcoin ETF, a total of $103.61 million has flowed out. Among them, Fidelity FBTC, ARKB, and BITB have become the main targets for fund outflows, with outflows of $75.56 million, $27.85 million, and $12.76 million respectively. It is worth noting that there are still a few ETFs that attract funds against the trend, such as Invesco BTCO and BlackRock IBIT, which received inflows of $10.02 million and $2.54 million respectively. Currently, the total assets of Bitcoin ETFs have reached $147.17 billion, accounting for about 6.6% of Bitcoin's market cap.

The situation for Ethereum ETFs is even more severe, with total outflows reaching $140.75 million. Fidelity FETH, Grayscale ETH, and Bitwise ETHW have become the hardest-hit areas for fund withdrawals, with outflows of $63.4 million, $36.37 million, and $23.88 million respectively. Even more concerning is that none of the 9 Ethereum ETFs have managed to attract new capital inflows, resulting in total assets dropping to $27.48 billion, accounting for only 5.45% of Ethereum's market value.

In terms of price performance, Bitcoin is currently hovering around $112,348, with a weekly decline of 3.4% and a total market capitalization of approximately $2.238 trillion. The performance of Ethereum is also not optimistic, with a price around $4,155 and a market capitalization of $502.1 billion, and a noticeable decrease in trading volume.

In light of the current market situation, analysts expect Bitcoin to remain relatively stable in the range of $112,000 to $119,000 in the short term. Meanwhile, Ethereum may face further downward pressure before the end of September. Interestingly, the market humorously refers to this wave of correction as "September Red 2025."

Despite the current market atmosphere being sluggish, experienced investors believe that this could be a breeding period for the next investment opportunity. Some forward-thinking funds are closely monitoring market trends, preparing to position themselves at the right moment. In this uncertain market environment, investors need to remain vigilant while also keeping an open mind towards potential opportunities.
