The crypto market is showing early signs of an altcoin season as Bitcoin’s dominance continues to slip. $BTC BTC dominance, which stood near 65% in May 2025, has now fallen to around 59%, reflecting a growing shift of capital into alternative cryptocurrencies.
The Altcoin Season Index currently hovers between 40–53, suggesting that while a full altseason isn’t confirmed yet (threshold 75+), momentum is building. Analysts at Coinbase predict a potential full-scale altseason could begin in early September, driven by liquidity inflows, ETF adoption, and improved market depth.
Ethereum is leading the charge, with experts noting that we may be in the middle of an “Ethereum Season” — historically a precursor to wider altcoin rallies. If confirmed, this cycle could last 4–5 months, with a peak expected in late 2025 or early 2026.
