Altcoin Season Breakout? Index Signals Shift After Months of Bleeding

The Altcoin Season Index has just broken out of a multi-month downtrend, sparking hopes that a long-awaited altcoin rally could be on the horizon.
According to analyst Titan of Crypto, this marks a potential shift in market dynamics after a prolonged stretch dominated by Bitcoin.
Sitting at 29 at the time of writing, the index is still firmly in Bitcoin Season territory (anything under 25 is considered BTC-dominant), but the recent trendline break suggests momentum may be turning in favor of alts.
The breakout, clearly marked on the chart, ends a steep decline that began in late 2024, when altcoins consistently underperformed.
“Still deep in Bitcoin Season territory, but pressure is building… If momentum continues, #Alts might catch a bid soon,” Titan noted.
The Altcoin Season Index measures whether the majority of top 50 altcoins are outperforming Bitcoin over a 90-day period. For full-fledged altcoin season, that number must rise above 75 — a long way from here, but the breakout is a start.
