Ethereum's price spiked above $3,600 after rumors that the SEC has asked ETF applicants to resubmit filings. Trading volumes exceeded 200% in the past day as sentiment turned bullish on a potential ETF approval, similar to what happened in January for Bitcoin ETFs. ETH's market cap increased by half of Solana's in just 3 minutes during the spike, creating the largest ever daily candle. If approved, ETH could quickly reach $4,000-$5,000 by year's end. Without approval, prices may retrace to $3,000.
