According to Coinglass data, Ethereum experienced a significant increase in May, with a nearly 30% increase, thanks to the approval of the Ethereum ETF 19-b application by the US Securities and Exchange Commission. This is the best monthly performance since the 46% increase in February. Historical data shows that May is usually the strongest month for Ethereum, with an average increase of 31%. In comparison, Bitcoin has also shown positive trends, rising more than 12% in May, attempting to recover from the 15% decline in April. Given the current trends and narrative favoring Ethereum, Ethereum may continue to outperform Bitcoin, as the ETH/BTC ratio has maintained positive growth so far this year, indicating a shift in Ethereum's dominant position.
