According to Michaël van de Poppe, the current altcoin market capitalization (OTHERS) against Bitcoin (BTC) is demonstrating a significant bullish divergence. This technical pattern, last seen at the major altcoin bottom in 2019, suggests a potential upward trend for altcoins relative to BTC. Traders should monitor this signal as it historically marked a turning point for altcoin performance compared to Bitcoin (Source: Michaël van de Poppe on Twitter, April 27, 2025).
