According to Michaël van de Poppe (@CryptoMichNL), Ethereum (ETH) is maintaining strong price action, indicating a gradual momentum shift towards altcoins. Verified trading data shows that ETH continues to outperform Bitcoin in recent sessions, with altcoins gaining increasing capital inflow and positive relative strength (source: @CryptoMichNL, June 4, 2025). This shift suggests traders should closely monitor ETH and major altcoins for breakout opportunities, as the capital rotation trend could drive higher volatility and liquidity across the altcoin sector.
