The Altcoin season index has increased to 71, which increases optimism among analysts that the cryptography market can be in the transition from a season of Ethereum (ETH) to a full altcoin season.
Beyond the index, market observers also indicate additional signals that suggest that a broader Rally of Altcoin can be on the horizon.
From ETH to low layers: analysts discuss what is still in market rotation

According to the data of the Blockchain Center, the index of the Altcoin season has risen from 59 yesterday to 71 at the time of the publication. Usually, a reading above 75 indicates the beginning of an Altseation season, where 75% of the 50 best Altcoins exceed Bitcoin for a period of 90 days.
While the index has not yet crossed that threshold, its rapid ascent has already caught the attention of merchants.
“The Altcoin season is in full validity, and finally it seems that the change from ETH to all other coins is about to happen,” an analyst published.
In addition, Merlijn also highlighted another important sign. In an X publication (previously Twitter), he said that Bitcoin Dominance (BTC.D), which tracks Bitcoin’s participation in the total cryptography market cover, slid below a key support level. Merlijn emphasized that this fall is happening quickly, instead of gradually.
“Each cycle, this marks the same result: Bitcoin cools. The ALTS ignite. The rotation does not come. It is already here. This is how the Altseasas begin,” he added.

From a technical perspective, another analyst attracted parallel to historical patterns. He described that in 2017, Altcoins organized a break after consolidation, which caused one of the most dramatic manifestations in Crypto’s history.
In addition, he pointed out that the current configuration is very similar to that period. The structure shows family signs: a descending wedge, a confirmed break and a current accumulation phase where investors gradually position themselves. According to their analysis, these factors together suggest that the conditions for another significant increase in Altcoin can already be in place.
Meanwhile, the outstanding investor Lark Davis highlighted the recent outbreak in Altcoins, noting that they are leaving a rise triangle formation.
“The consolidation since mid -August now seems ready to solve more.

Therefore, all these signs point to a capital rotation to Altcoins in September. But what happens later? Well, according to Altcoin Vector, the market phase has changed Ethereum to Altcoins of low lid, a movement that, based on past patterns, points out the interest that fades in the broader Altcoin sector. This change has often preceded a restart to Bitcoin again.
“But this is not the complete image. The phase could return to ETH once its accumulation process is completed: compression is being built and ETH can be prepared for the next section,” said Altcoin Vector.
What is different in the September Altcoin season?
Amid the frenzy of the Altcoin season, analysts point out that the September rally comes with a different dynamic. Simon Ded, founder of Moonrock Capital, warned that together with legitimate manifestations, speculative tokens with inflated assessments and questionable volume are also pumping.

“We are entering the high season, but the scams will pump more difficult. Tokens such as MyX or IP are clearly only well executed of the Float/High FDV extraction game. And then there are coins like M or TDCCP that I had not even heard before, but exchanging ridiculous assessments with a lot of volume, which is clearly false,” he said.
He added that the next months could be highly profitable, but equally full of schemes, which makes the precautionary crucial.

In particular, market veterans also emphasize that the environment in 2025 is not the same as in the past cycles. Gareth Soloway noted that the ‘Altcoin Altcoin market’ has changed Altcoins to small capitalization shares.
“The recipe for a daily gain of more than 1000%is to buy an Altcoin and affirm that it will be a reserve currency or the leader of the use case. First was BMNR, yesterday Octo, today CWD. Insanity,” Solway said.
Therefore, the increase in the index of the Altcoin season, the fall of Bitcoin’s domain and technical configurations suggest that an Altcoin rally can be underway. But with speculation and scams also increase, this unique cycle demands both optimism and caution.
