Key TakeawaysETH/BTC ratio climbed to 0.0313, its highest level since January.Ether outperformed Bitcoin over the past week, rising 4% versus BTC’s 3.9%.Ethereum added 284,000 new users in Q1, up 82% quarter-over-quarter.Stablecoin supply on Ethereum reached a record $180 billion.Analysts say ETH/BTC must reclaim 0.035 to confirm a broader altcoin rotation.ETH/BTC Ratio Rebounds From 2026 LowsThe ETH/BTC ratio rose to around 0.0313 this week, marking its highest level in roughly three months after bottoming near 0.028 in February.The move suggests Ether is beginning to outperform Bitcoin again after months of weakness. While the ratio remains below its January high near 0.038, the recent rebound is being viewed as an early sign that capital may be rotating back into Ethereum and higher-risk crypto assets.Why the ETH/BTC Ratio MattersThe ETH/BTC ratio is one of the most closely watched indicators of market risk appetite in crypto.A rising ratio typically signals that investors are moving from Bitcoin into Ethereum and altcoins.A falling ratio suggests traders prefer Bitcoin’s relative safety.Historically, stronger ETH/BTC performance has often coincided with broader altcoin rallies and periods of improving market sentiment.Ethereum’s Fundamentals Are ImprovingEthereum’s rebound is being supported by stronger network activity rather than price action alone.In Q1:Ethereum added 284,000 new users, up 82% quarter-over-quarter.Total transactions reached a record 200.4 million.Stablecoin supply on the network climbed to an all-time high of $180 billion.Ethereum now accounts for roughly 60% of global stablecoin supply, reinforcing its role as the primary settlement layer for tokenized dollars, DeFi, and institutional blockchain activity.Stablecoin Growth Strengthens Ethereum’s Long-Term CaseThe growth in stablecoin supply is becoming one of Ethereum’s strongest structural tailwinds.Token Terminal estimates Ethereum’s stablecoin supply has increased 150% over the past three years, while the network could capture as much as $850 billion in additional stablecoin flows by 2030 if adoption continues. Major institutions including BlackRock, JPMorgan, and Amundi are already using Ethereum for tokenized financial products.Key Level to Watch: 0.035Despite the rebound, ETH is still more than 50% below its 52-week high.Analysts say the ETH/BTC ratio must reclaim the 0.035 level on a weekly closing basis to confirm that this is more than a short-term bounce. A move above that zone would provide stronger evidence that a broader rotation into Ethereum and altcoins is underway.
