Golden Finance reported that Citigroup (C) said in a research report last week that the net inflow of U.S. spot Ethereum ETFs may be only 30%-35% of the spot Bitcoin equivalent, and the distribution is biased to the downside. The report said that this level means that the net inflow of funds will reach US$4.7 billion to US$5.4 billion in six months. In addition, the bank said that the beta value of inflows and Ethereum returns relative to such funds may be lower than the analysis results.
