Altcoin season buzz on social media has surged to a three-month high, with Santiment data showing mentions of 'altcoinseason' reaching 544 on May 4, the highest since February 5, and 'altseason' mentions hitting their highest since March 18. This renewed retail interest follows notable rallies in several altcoins, fueling hopes of a broader rotation away from Bitcoin. However, analyst Altcoin Vector warns of a structural issue: the OTHERS/BTC ratio (total altcoin market cap excluding top 10 coins relative to Bitcoin) is recovering, but the ETH/BTC ratio remains weak. This breaks the typical rotation pattern where Ethereum leads altcoins higher before capital flows into smaller tokens. The divergence suggests altcoins may be front-running a potential rotation, skipping Ethereum's leadership phase. For the current altcoin push to become sustainable, Ethereum needs to reclaim relative strength against Bitcoin. If ETH/BTC stays compressed, gains in smaller altcoins could unwind quickly in the event of Bitcoin weakness.
