Bitcoin Dominance Is Rising—and It’s Squeezing Altcoins

Bitcoin dominance, %. Source: Cointelegraph/TradingViewBitcoin’s market dominance is once again tightening its grip on crypto capital flows. After briefly dipping in September, BTC dominance has resumed an upward trend and currently sits near 59%, marking a continued “Bitcoin season.”
This shift is being driven by institutional capital, not retail speculation. Spot Bitcoin ETFs—led by BlackRock’s IBIT with over $25 billion in 2025 inflows—have reinforced BTC’s role as the primary institutional asset. In contrast, altcoins are increasingly viewed as fragmented, illiquid, and higher-risk. With BTC dominance printing higher lows, capital rotation is favoring Bitcoin, not the broader altcoin market.
