According to Mars Finance, Matrixport stated on platform X that over the past year, crypto Twitter has been calling for altcoin rebounds almost every month, but none have succeeded. However, the altcoin rebounds are not driven by chart patterns or some assumed lagging actions behind Bitcoin. Instead, they rely on the decline of Bitcoin's dominance and the rise in total cryptocurrency market value. As Bitcoin's dominance rises, Ethereum has performed poorly, and few other cryptocurrencies have become credible competitors in this cycle. Without a strong alternative narrative or leadership, other cryptocurrencies may continue to lag behind. Our other cryptocurrency performance models currently support this view, continuing to favor Bitcoin.
