Citi (C) said in a research note last week that net inflows into U.S. spot Ethereum ETFs are likely to be only 30% to 35% of the spot Bitcoin equivalent, with the distribution skewed to the downside. This level implies a net inflow of $4.70 billion to $5.40 billion over a six-month period, the report said. In addition, the bank said the beta value of inflows and Ethereum returns relative to such funds may be lower than the analysis.
