According to Michaël van de Poppe, a notable cryptocurrency analyst, altcoins often appear underperforming before a significant bull run begins. This observation suggests that traders should monitor altcoin price movements closely for potential entry points. Historically, altcoins have shown considerable gains post such bearish phases. Investors might consider diversifying their portfolios by including promising altcoins with strong fundamentals to capitalize on upcoming market surges. [Source: Michaël van de Poppe Twitter]
