Bitcoin’s bullish sentiment in 2025, driven by ETF approvals and institutional adoption, uplifts altcoins like Ethereum and Solana. Its 59.1% market dominance sets the tone, with altcoins following its 146% rally. However, negative sentiment from tariffs or corrections can disproportionately hit altcoins, causing up to 60% declines. Positive regulatory shifts amplify cross-market confidence.
