币界网报道：Ethereum ETFs could attract up to $300 million in net inflows within their first five months if approved by the SEC, according to K33 Research analysts. While significantly lower than Bitcoin ETFs' $12 billion inflows, the muted expectations reflect cautious optimism amid regulatory uncertainty. The SEC has delayed decisions on spot Ethereum ETF applications from major firms like BlackRock and Grayscale, with final deadlines extending to May 2024. Analysts suggest Ethereum's futures market activity—where open interest recently hit $8 billion—may influence the SEC's stance, as futures-based ETFs already exist. However, concerns over Ethereum's classification as a security and staking mechanics pose additional hurdles. Market observers note that even modest inflows could positively impact ETH's price, given its smaller market cap compared to Bitcoin. The report highlights that Ethereum's 26% year-to-date underperformance against Bitcoin may reverse if ETF approvals materialize, though regulatory clarity remains the key bottleneck. Institutional interest appears tempered until the SEC provides clearer guidance, with some firms exploring alternative crypto ETPs in more favorable jurisdictions like Europe.
