An analyst at Sygnum Bank said: Inflows into an Ethereum ETF in its first year of trading are likely to drop significantly compared to inflows into a Bitcoin spot ETF. Katalin Tischhauser, head of research at Sygnum Bank, said: "With Ethereum's lower visibility, which is likely to mean slower adoption, and with a market cap of only a third of Bitcoin's, we expect relative inflows to be between 15% and 35% of Bitcoin, so inflows are expected to be between $5 billion and $10 billion in the first year." The analyst also predicted that a spot Bitcoin ETF could attract inflows of between $30 billion and $50 billion in the first 12 months of trading, based on current and historical market patterns.
