The crypto market is closing out Q3 on a bullish note, with Bitcoin (BTC) and Ethereum (ETH) showing renewed strength. Analysts now believe Bitcoin may have one last rally left before stepping aside for altcoins, setting the stage for a long-anticipated altseason in Q4 2025.

Bitcoin Dominance Declines

Data from CoinMarketCap shows Bitcoin Dominance at 58%, continuing a steady downtrend. Ethereum holds nearly 13% of the market, while altcoins collectively account for about 30%. This shift is viewed as one of the strongest signals that an explosive altseason is on the horizon.

Despite a brief correction after setting new all-time highs (ATHs) in August, both BTC and ETH have entered a recovery phase. Analysts now expect Bitcoin to potentially reach as high as $140,000 before momentum shifts decisively to altcoins.

Ethereum and Altcoins Gather Strength

Ethereum’s price recovery has reinforced confidence that it will take on a larger share of market momentum in the months ahead. Altcoins are also showing strong technical setups, with several already breaking into new ATH territory. Chart patterns such as a completed “cup and handle” formation suggest a wider breakout is forming across the altcoin market.

The weakening of Bitcoin’s dominance means liquidity is slowly moving into Ethereum and smaller assets, which could accelerate as Q4 begins. For many traders, this aligns with the cycle timing often seen in previous bull markets—Bitcoin leads, then altcoins run.

Altseason Outlook for Q4 2025

If Bitcoin completes its projected final push, analysts expect a rapid rotation into altcoins. The peak phase of altseason is forecast for late Q4 2025, when altcoins could post exponential gains and new ATHs across the board.

For now, Bitcoin remains the market driver, but the growing cracks in dominance charts suggest the window for altcoin momentum is opening quickly. The coming quarter may prove to be one of the most volatile and profitable phases of the cycle.
