From a trading perspective, this 12.50% surge in ETH/BTC on May 8, 2025, opens multiple opportunities for both short-term and long-term strategies. For scalpers, the heightened volatility in the ETH/BTC pair, with intraday price swings of up to 5% between 10:00 AM and 2:00 PM UTC, suggests potential for quick profits through tight stop-loss orders around key support at 0.056 and resistance at 0.060. Swing traders might consider Ethereum’s relative strength as a signal to overweight ETH in portfolios, especially as on-chain data shows a 20% increase in Ethereum wallet activity over the past 48 hours ending at 3:00 PM UTC on May 8. Conversely, Bitcoin’s underperformance could indicate a temporary pullback, with BTC/USD trading down 2.3% to $62,500 by 4:00 PM UTC on the same day on Binance.

Institutional money flow, evident from a 15% uptick in Ethereum futures open interest on CME at 5:00 PM UTC, suggests big players are betting on ETH’s outperformance, potentially driving further upside. Traders should monitor these cross-asset movements for clues on sustained momentum.
