Ethereum ($ETH) has underperformed compared to Bitcoin ($BTC), but in the past week, Ethereum ETFs have seen their best performance since launch. According to data from SoSoValue, the inflow for spot $ETH ETFs reached $515 million last week, significantly higher than the previous week's $154 million. This marks the highest weekly inflow since launch, with net assets increasing from $6.94 billion to $9.15 billion in two weeks. However, the outflows from the Grayscale Ethereum Trust continue to pressure prices, with a cumulative net outflow of $178 million. The ETH/BTC ratio is at a three-year low, indicating Ethereum's poor performance compared to Bitcoin. Meanwhile, Solana is eating into Ethereum's market share, with the SOL/ETH ratio reaching an all-time high.
