Top Three Altcoins To Watch Closely Before Bullish ‘Q4’ Kicks In

With the final quarter of 2025 approaching, traders are preparing for a possible shift toward altcoins. Charts for Bitcoin dominance (BTC.D), Tether dominance (USDT.D), and the Altseason Index hint that market conditions may soon favor altcoins. According to an analyst, Ethereum (ETH), Immutable X (IMX), and Solana (SOL) are among the tokens showing setups worth tracking.

Bitcoin Dominance and Altseason Index

Bitcoin dominance recently tested resistance near 59.3 percent. A move lower toward 57 percent would signal room for altcoins to gain. The Altseason Index sits at 73, just below the mark that defines an altcoin season. The reading shows that while Bitcoin remains strong, the market is edging closer to a phase that benefits altcoins.

Tether Dominance Weakens

Tether dominance rejected at the 200-day moving average and key Fibonacci resistance. The chart has since turned lower, suggesting stablecoin supply could flow back into Bitcoin and altcoins. A sustained drop in USDT.D would strengthen the case for a broader market recovery in October.

Ethereum’s Support Levels

Ethereum has shown a reversal on the daily chart. A dip into the $3,600–$3,400 area would match long-term Fibonacci support and set up bullish divergence. Resistance sits between $4,185 and $4,250, while the $4,400 zone remains a high-risk area.

Solana Near Key Zones

Solana bounced from $190 but may retest lower levels if weakness continues. The $176–$166 range combines the 200-day moving average and major retracement levels. A reaction here would likely confirm support and open the door for a rebound.

Immutable X as an Early Signal

Immutable X has often moved ahead of the wider market. Price action on IMX could provide early signs of whether altcoins are ready to gain strength.

Q4 Predictions

The coming weeks may bring more downside before a recovery. If both Bitcoin and Tether dominance confirm bearish patterns, conditions would favor altcoins. Ethereum, Solana, and Immutable X stand out as important projects to monitor as October trading begins.
