Social media mentions of 'altcoinseason' have surged to a three-month high, according to BeInCrypto, with Santiment data showing a significant increase in early May. Despite the renewed interest and notable rallies in several altcoins, Altcoin Vector warns that weak Ethereum (ETH) leadership could undermine the move. The OTHERS/BTC ratio is recovering, but the ETH/BTC ratio remains weak, breaking the typical rotation pattern where Ethereum leads altcoins higher. This divergence suggests altcoins may be prematurely front-running a rotation, potentially risking gains if Bitcoin weakens.
