Altcoin Season Index Rises to 51 as Solana Meme-Coin Activity Cools

Altcoin season is warming with the Altcoin Season Index climbing to 51, but the most speculative assets are lagging and the Solana network is showing early risk-off signals. According to BeInCrypto, a 30-day basket of meme coins fell 19.1% versus a 9.8% drop for mid-cap altcoins, leaving meme outperformance at negative 9.3 percentage points even as the two baskets remain highly correlated at 0.90. Solana led networks with more than $471 million in meme-coin volume over seven days, versus Ethereum near $50 million, but its weekly DEX volume slid from roughly $5.2 billion in the week of June 5 to about $1.1 billion by June 14.
