Social media excitement around altcoins is growing as major altcoin market indicators hit their highest levels since December.
Altcoin-related market indicators are flashing bullish signals as the crypto community ramps up discussions about a potential altseason. Analysts believe that if altcoins break into price discovery again, it could spark renewed investor interest.
Earlier today, CoinGlass’ altcoin season index surged to 78 out of 100, marking the highest point since last December. CoinMarketCap’s altseason indicator is also near its yearly peak at 67, confirming that altcoins are gaining momentum.
The total altcoin market cap, excluding Bitcoin BTC $92 511 24h volatility: 0.2% Market cap: $1.85 T Vol. 24h: $52.84 B and stablecoins, is currently at $1.63 trillion, just shy of the $1.64 trillion record reached in November 2024.
Ethereum’s recent breakout and its outperformance relative to Bitcoin point to the early stages of a fresh altcoin rally. Coins such as Hyperliquid (HYPE) have already hit new all-time highs. BTC’s market dominance has also declined, allowing altcoins to rotate higher.
Market watchers expect that the Fed’s potential interest rate cut next week could act as a catalyst for further altcoin growth.
