Last Friday, there was a divergence in the inflow of funds into encrypted ETFs: mainstream assets were under pressure, and counterfeit products were taking advantage of the trend to attract funds According to BlockBeats, on December 8th, the cryptocurrency ETF market showed significant differentiation last Friday: Bitcoin and Ethereum related products experienced significant net outflows, while various altcoin ETFs, especially XRP ETFs, continued to attract institutional funds, indicating a significant adjustment in fund structure. There is a significant outflow of mainstream asset funds: The net daily outflow of Bitcoin spot ETFs was about $195 million, one of the weakest performances in weeks. The Ethereum ETF also recorded a significant net outflow, ending the brief net inflow earlier this week. Analysis suggests that macroeconomic uncertainty, particularly the pending release of inflation data, is prompting institutions to temporarily reduce risks rather than fully withdraw. The decline in trading volume of mainstream ETFs also reflects investors' temporary wait-and-see attitude. In sharp contrast to the pressure on BTC and ETH, XRP ETFs have maintained net inflows for several consecutive weeks, with a cumulative inflow of nearly $900 million, indicating that institutions' confidence in their relative value and potential regulatory benefits continues to strengthen. Solana and other altcoin ETFs also recorded small net inflows, indicating that market funds have not withdrawn but are rotating internally. As the end of the year approaches and macro uncertainty increases, institutional investors no longer view the cryptocurrency market as a single risk asset, but rather as a more 'selective target': BTC and ETH, which are more susceptible to macro drag when reducing positions; Altcoins with stronger allocation momentum or clearer narrative. Friday's ETF fund flow data highlights the new trend of institutions in turbulent environments: exiting the mainstream and not exiting the market; Increase holdings of alternative assets with stronger resistance to volatility.
