The approval of spot Ethereum ETFs has sparked discussions about their potential impact compared to Bitcoin ETFs. Analysts predict varying levels of demand for ETH ETFs, with estimates ranging from 10-25% of BTC's demand. Institutional interest in ETH ETFs seems lower initially. The SEC's approval of ETH ETFs is seen as significant for legitimizing crypto as an asset class. ETH's price surge and market performance post-ETF approval are notable, with expectations of hitting $4,500 before ETFs launch. Demand for Bitcoin ETFs remains strong, with significant inflows and a supply shock due to ETFs buying more Bitcoin than mined.
