According to Miles Deutscher, the ETH/BTC pair is closely watched as a leading indicator for the start of alt season, with a requirement for ETH to close above its 200-day moving average and set a new 90-day high. Currently, ETH/BTC is rated yellow with a score of 0.5, indicating that ETH has not yet outperformed BTC to ignite a broader altcoin rally. Traders should monitor these technical signals, as breaking above the 200-day MA has historically preceded strong altcoin market performance (source: @milesdeutscher, June 9, 2025).
