Blockchain Center Signals 3-Day Altcoin Season: Reality or Mirage?
The altcoin season continues to thrive, and cryptocurrency enthusiasts on social platforms are celebrating the surge in prices. Data from Grok indicates that X feeds are alive with activity, featuring numerous posts that support this trend. As per Grok's findings, the surge in social media discussions coincides perfectly with the Altcoin Season Index (ASI) surpassing the 75 out of 100 threshold on September 10.

At the same time, while the ASI indicates an altcoin season, many skeptics claim they just can’t perceive it. “Holy sh**, the Altcoin Season Index just reached 84 – the highest this year,” exclaimed influencer Lark Davis on X. However, not everyone is persuaded, as one user retorted: “Where is altcoin season? I can’t see it.”

Some believe this current altcoin season is merely a temporary phase, unlikely to last long. “This altcoin season is predicted to endure for 5 days,” cautioned one X user. “Take profits — something bad is on the horizon.” As of Sept. 13, 2025, at 4:23 p.m. Eastern, archived data reveals that blockchaincenter.net’s ASI is steady at 80.

It might be a month of altcoin season, but it’s certainly not an altcoin season year. The site’s monthly score stands at 88 out of 100, while the 12-month score lags behind at just 35. Since any score above 75 indicates an altcoin season, this suggests that three-quarters of the top 50 altcoins have outperformed bitcoin’s market performance over the past 90 days.

The recent surge in altcoin season has fans rejoicing, yet a sense of caution remains. The cycle of excitement followed by diminishing momentum has recurred since 2021, leaving traders cautious and yearning for a prolonged season. So far, this one has climbed nearly as high as it did in December 2024. Whether this moment marks a significant change or yet another brief surge, only time will reveal the true trajectory of the crypto market ahead.
