Ethereum (ETH) has recently surged over 25%, driven by optimism surrounding potential spot Ethereum ETF approvals in the U.S. Currently trading at $3,788.21, ETH has seen significant gains of 25.91% over the past week and 19.21% in the past month, though it remains 22.54% below its all-time high of $4,891.70. Key indicators supporting this bullish trend include a substantial rise in ETH futures open interest, which increased from 2.8 million to 3.2 million on May 20, and significant accumulation by permanent holders who purchased over 100,000 ETH amid the ETF approval rumors. These factors, coupled with increased investor confidence, suggest that Ethereum's upward momentum is likely to continue, with potential ETF approvals acting as a significant catalyst for further price increases.
