Altseason buzz is building, and the latest data is starting to support the hype. Fresh market insights reveal that Ethereum is taking the lead, overtaking Bitcoin across several major indicators—and bringing the altcoin market along for the ride.
According to CryptoQuant data from July 23, Ethereum has outpaced Bitcoin by 72% since April, with the ETH/BTC ratio climbing from 0.018 to 0.031—its highest point since January. This signals a strong shift from ETH’s previously undervalued position.
Ethereum has also just surpassed Bitcoin in weekly spot trading volume, recording $25.7 billion compared to Bitcoin’s $24.4 billion. It’s the first time ETH has taken the lead in spot volume since June 2024, reflecting a significant shift in market sentiment.
Adding momentum to the trend is a notable shift in U.S.-listed exchange-traded fund (ETF) flows. The ETH/BTC ETF holding ratio has surged from 0.05 to 0.12, signaling a clear institutional tilt toward Ethereum. ETH ETFs have now recorded 15 consecutive days of inflows, while Bitcoin ETFs have reversed course, posting steady outflows.
On-chain activity supports this shift as well. The ETH/BTC exchange inflow ratio remains low, indicating that fewer ETH are being moved onto exchanges compared to BTC. This typically suggests reduced sell pressure for Ethereum and sets the stage for continued outperformance—provided demand stays strong.
The transition is also reflected in a weakening of Bitcoin’s dominance. According to Glassnode, BTC’s market share has dropped from 63.76% to 60.78% in just a week—a steep 2.98 percentage point fall, and one of the sharpest weekly declines in 2025.
As capital flows away from Bitcoin, altcoins are starting to see renewed interest and strong upward momentum.
Altseason finally here?
Even with recent pullbacks in tokens like Solana (SOL) and XRP, the altcoin market is flashing promising signals. Total altcoin spot trading volume has surged to $67 billion—its highest level since March—pointing to renewed investor interest.
Social sentiment supports this shift. Data from Santiment shows that crypto discussions across platforms like X, Telegram, and Reddit are increasingly centered around altcoins rather than Bitcoin, despite BTC’s recent rise to $123,000.
This signals a clear rotation in market attention. Ethereum and the broader altcoin space now dominate both capital flows and community focus, marking a break from Bitcoin’s dominance in Q2.
Still, the momentum remains fragile. The Altcoin Season Index, which climbed to 55 earlier this week, has slipped to 34—well below the 75 threshold typically required to confirm a true altseason. While we’re not there yet, if the trends in trading volume, ETF flows, and sentiment continue to build, the stage could be set for a sustained altcoin rally.
