- Bitcoin dominance is falling fast while altcoins like Ethereum surge, hinting that Altseason 2025 may finally be getting underway.
- Low Google search interest despite Bitcoin’s new highs signals retail traders haven’t jumped in yet, leaving room for big altcoin gains.
- Ethereum’s breakout above $3,900 shows major altcoins are leading the charge as smaller tokens prepare to ride the next bullish wave.
Altcoins may be ready to shine as signs of an incoming Altseason 2025 continue to strengthen across key market indicators. After months of increasing momentum, Bitcoin’s supremacy has begun to wane, indicating that money may soon shift to other cryptocurrencies. This change occurs even if institutional backing for Bitcoin is increasing and it has hit fresh all-time highs above $100,000.

Meanwhile, retail interest remains low based on Google Trends data, hinting that the real retail-driven rally may not have even begun. Historically, altseasons often emerge after Bitcoin leads the market and investors seek higher returns in smaller-cap assets.
Bitcoin Dominance Slips as Altcoins Awaken
Bitcoin’s dominance peaked near 66% in late June but has since dropped to around 63.4%. This marks a significant shift in market sentiment. Analyst Stockmoney Lizards view this decline as a signal that altcoins are beginning to outperform BTC. While Bitcoin continues to lead, its shrinking dominance suggests a healthy diversification of market attention.

Merlijn the Trader reinforced this view, pointing to historical patterns. According to his “Altcoin Cheat Sheet,” the current structure mirrors 2019 and 2020 mini-altseasons. A full-blown altseason, like in 2021, could soon unfold. Historical resistance lines on the altcoin index are now being tested again. Once broken, this may open the door for explosive altcoin rallies.

Retail Interest Remains Low Despite New Bitcoin Highs
Interestingly, Google search trends for Bitcoin remain low, even as prices push past previous highs. This contrasts with previous cycles where search spikes closely matched major rallies. The current divergence likely reflects growing institutional dominance and delayed retail participation. Once retail investors re-engage, the altcoin market could see more capital inflows.
Ethereum already shows signs of strength. It has doubled since April 2025 and recently broke above $3,900. This confirms growing confidence across leading altcoins. Analysts now believe ETH could pave the way for smaller-cap tokens to follow.
