Social media buzz over crypto altseason is surging again this week as altcoin market indicators jump to their strongest levels in 2025.

Altseason Index at a 9-Month High

Blockchain Center Altseason Index: 76/100

CoinGlass Altseason Index: 76/100

CoinMarketCap Altseason Indicator: 67/100

For context, Blockchain Center defines altseason as the period when 75% of the top 50 crypto assets outperform Bitcoin over the past 90 days.

All three metrics are now at their highest levels since December 2024, signaling that altcoins are outpacing BTC in a major way.

Market Signals From Pro Traders

“Once we see altcoin market as a whole back in price discovery, expect wider excitement and new participants,” he says.

Karan Singh Arora: Highlights that a 9-month high in the altseason index has traders leaning risk-on again.
