Altseason Momentum Peaks: Altcoins Surge to Highest Levels Since December

Altcoin markets are showing renewed strength as the altseason index climbs to its highest reading of 2025. Indicators from the Blockchain Center and CoinGlass hit a score of 76, while CoinMarketCap’s altseason gauge measures slightly lower at 67 — all signaling that altcoins are currently outpacing Bitcoin more than at any time since December.

Blockchain Center defines an altseason phase as when 75% of the top 50 cryptocurrencies outperform Bitcoin over the past 90 days. Traders are watching closely as this could signal the start of a broader market rally for alternative coins.

Total altcoin market capitalization is nearing historic levels, currently at $1.63 trillion, just shy of its November 2024 peak of $1.64 trillion. Observers note that renewed investor interest could push prices into price discovery, attracting fresh capital and increasing market participation.

Individual altcoins are seeing notable gains over the past 24 hours. Dogecoin has crossed $0.25, while Avalanche surged almost 11% to reach $28.70, its highest since January. Other strong performers include Hyperliquid, Stellar, Litecoin, and Toncoin, all climbing more than 3% in the same period.

As altcoins regain momentum, traders are positioning for a possible parabolic phase in the ongoing bull cycle, marking a return of risk-on sentiment in crypto markets.
