CryptoQuant’s data reveals a dramatic shift in the Ethereum-Bitcoin dynamic as ETH value relative to BTC has surged by 38% in just one week, indicating an altcoin rally might be underway. The ETH/BTC ratio, crucial for measuring these cryptocurrencies’ comparative strength, recently hit its lowest point since early 2020, a historical sign of potential market rebounds. CryptoQuant analysts highlight that this metric has entered a deep undervaluation zone not seen since 2019, preceded by notable Ethereum outperformance against Bitcoin in previous cycles. This resurgence is backed by an increase in ETH trading activity, with its spot volume reaching its highest ratio since August 2024 and a drop in sent to exchanges to a multi-year low, suggesting a lack of selling pressure, typically a bullish signal for investors. This trend is further amplified by accelerating inflows into Ethereum-focused exchange-traded funds (ETFs), indicating growing institutional confidence. Analysts attribute this renewed interest to Ethereum’s improved scalability and a favorable macroeconomic climate. If these trends continue, the current market structure could pave the way for Ethereum and other altcoins to regain momentum after months of lagging behind Bitcoin.
