Ethereum's Narrowing Narrative: Why BTC, SOL, and DeFi Risks Are Compressing ETH to Yield-Only

Ethereum's ETH/BTC ratio has fallen to 0.031—a multi-year low—as three simultaneous pressures compress its use cases. BTC absorbs geopolitical safe-haven demand, SOL's Alpenglow targets 100ms finality (8-128x faster than ETH), and DeFi ecosystem failures poison institutional sentiment. The ETHA-to-ETHB institutional rotation reveals that institutions want ETH only as a regulated yield product, not as a platform for DeFi composability.
