Social media buzz around crypto altseason is heating up again this week as altcoin market indicators reach their highest points of the year.
Both the Blockchain Center and CoinGlass altcoin season indexes report a score of 76 out of 100, while CoinMarketCap’s altseason indicator is slightly lower at 67. All three, however, mark their strongest readings since December.
According to the Blockchain Center, altseason is defined as the period when 75% of the top 50 cryptocurrencies outperform Bitcoin over the past 90 days.
Altseason typically represents a phase in each bull market when altcoins surge far ahead of Bitcoin, though pinpointing its exact timing this year has proven challenging.

What Altcoin Traders Expect Next
Altcoin market capitalization is approaching its 2021 all-time high, according to crypto trader “Daan Crypto Trades,” who shared his observation on Wednesday.
“Once the altcoin market as a whole enters price discovery, I expect it to spark broader excitement and a risk-on sentiment for alts,” he said, noting that this could also draw in new participants.
“With the altseason index hitting its strongest level in nine months, traders are starting to adopt a more risk-on approach,” added crypto educator Karan Singh Arora on Thursday.
The total altcoin market cap, excluding Bitcoin and stablecoins, currently stands at $1.63 trillion, nearing 2025 highs, according to TradingView. Its previous peak was $1.64 trillion in November 2024 and $1.7 trillion in November 2021.

“Altcoins are poised to go parabolic as phase 3 of altseason kicks in,” said crypto trader Ash Crypto.
