ETH/BTC chart is flashing some serious strength. Classic cup-and-handle and bull flag setups suggest a 30–55% upside by July. But the bigger story? Historically, ETH outperforming BTC has been the spark for altseasons. Analysts are watching this closely. Similar setups in 2017 and 2021 triggered parabolic moves across altcoins, some now project potential rallies up to 250x if patterns hold. With ETH aiming for key resistance levels, the next few weeks could set the stage. Is this the beginning of something way bigger?
