According to Crypto Rover, the U.S. SEC is questioning the legality of proposed Ethereum (ETH) and Solana (SOL) ETFs, highlighting concerns over staking mechanisms and their classification under U.S. investment law (source: Crypto Rover on Twitter, June 2, 2025). This development introduces significant regulatory uncertainty for ETH and SOL ETF approval timelines, which could increase volatility and pressure on both tokens’ spot prices. Traders should closely monitor SEC communications as further scrutiny may delay institutional inflows and affect broader crypto market sentiment.
