Altcoins Gain Momentum as Bitcoin Dominance Drops to 61.6%

The cryptocurrency market is experiencing a notable shift in capital flows as Bitcoin's market dominance has dropped to 61.6%, marking a 2.36% decrease.

Meanwhile, Ethereum and other altcoins are gaining traction, with Ethereum dominance climbing to 10.9% (+1.51%) and “Others” rising to 27.6% (+0.85%), according to CoinMarketCap data.

Declining BTC dominance signals changing investor sentiment

Bitcoin dominance, which reflects Bitcoin’s share of the total cryptocurrency market cap, is often used as a barometer of market sentiment. A decrease typically signals growing confidence in altcoins or heightened appetite for risk.

Over the past month, BTC dominance has slipped from 64% to its current 61.6% level. Compared to its recent high of 65.1% on June 27, 2025, this trend indicates investors are rotating capital into Ethereum and emerging projects.

Ethereum’s dominance rose from 9.3% last month to 10.9% today, a significant move that aligns with rising institutional interest and the broader narrative of a potential “altseason.” Likewise, the category of “Others”—which includes mid- and small-cap altcoins—gained 1% over the month, suggesting broader diversification among traders.

Market implications and outlook

This redistribution of market share may reflect increased bullishness around Ethereum’s upcoming upgrades, the growth of real-world asset (RWA) tokenization, and speculation around ETF approvals. Ethereum’s 60%+ 7-day price gain, as seen in other data, also reinforces the current altcoin momentum.

If Bitcoin’s dominance continues to decline, it may signal the start of a stronger altcoin rally. However, traders should remain cautious, as sudden shifts in sentiment could lead to volatility, especially if BTC reasserts dominance during broader market corrections.
