Key takeaways
Altcoins have a history of dipping in August before rallying hard, and 2025 may be no different. With Ethereum gaining traction, Bitcoin dominance slipping, altseason may not be far.
August has a reputation for shaking up the altcoin market, often dipping before coming back stronger. This year, altcoins are once again in decline, so it is natural to wonder if we’re on the verge of another major breakout.
With bold predictions around Ethereum’s [ETH] rise and its usual role in leading altcoin rallies, we may be about to watch history repeat itself.
August pain, September gains?
Altcoins seem to follow a familiar script every August — sharp corrections followed by explosive comebacks.
As AshCrypto pointed out on X, 2023 and 2024 saw altcoin market caps plunge 28% and 40% respectively, only to rally by over 140% in the months that followed.

In 2025, altcoins are already down 13% from their peak, and another 8-10% drop could be on the cards before a potential bottom.
If past patterns hold, this dip might just be the setup for yet another altseason breakout… one that investors will be watching closely.
Ethereum flashes potential altseason
Just days after projecting Ethereum to hit $8K, Eric Trump returned to X with a bold “buy the dip” sign; this time tagging both Bitcoin [BTC] and ETH.

While endorsements aren’t uncommon, Ethereum’s role as a harbinger for altseason makes this more than just noise.

The Altcoin Season Index has climbed to 45, moving steadily toward the 75+ mark that typically defines a full-fledged altseason.
Simultaneously, Bitcoin dominance [BTC.D] has dropped from above 65% in July to around 62%; a sign that capital is slowly rotating out of BTC and into altcoins.

If BTC dominance continues to slide while ETH holds strong or rallies, it could trigger a broader altcoin surge.
Eric Trump’s call is part of a sentiment already building in the charts: that altcoins may be coiling for their next breakout.
