Recent market data suggests the cryptocurrency sector may be entering the early stages of altseason, with Ethereum leading the charge against Bitcoin.
Ethereum (ETH) is trading at $4,502.81, up 4.6% in the past 24 hours and more than 40% over the last month. The ETH/BTC ratio has climbed for five consecutive days to 0.037, marking its strongest run since early 2024. Technical indicators show momentum building, with ETH’s MACD firmly bullish and its RSI nearing overbought levels.
Analysts point to a confirmed breakdown in the BTC/ETH technical setup — a pattern that in past cycles has preceded capital rotation from Bitcoin into Ethereum, and subsequently into other large- and mid-cap altcoins. Bitcoin dominance is slipping, and Ethereum’s bullish crossover on the MACD aligns with historical triggers for broad altcoin rallies.
Altseason is knocking, but the door isn’t wide open yet. ETH leading the charge with a strong ETH/BTC breakout, bullish MACD, and rising institutional flows hints at the early stages, but the classic confirmation needs BTC dominance <60% and broader alt surge.

Institutional demand is adding fuel to the trend, with recent Ethereum purchases totaling around $19 million. Social sentiment is also turning sharply positive, with discussions on X (formerly Twitter) centred on Ethereum’s role in decentralized finance and expectations of a larger market move.
The Altcoin Season Index still shows Bitcoin in control, but analysts say sentiment is shifting. Key confirmation signals would include ETH/BTC holding above 0.035–0.036 and Bitcoin dominance dropping below 60%.
While Bitcoin remains near record highs at $119,831.96, its slower growth rate compared to Ethereum is prompting some traders to rotate into higher-beta altcoins. Rising market cap and open interest for ETH indicate growing investor conviction.
Market strategists describe the current environment as a prelude to altseason — with Ethereum’s surge setting the stage for potential large-scale altcoin gains if liquidity and technical conditions continue to align.
CoinGecko’s data confirms ETH is currently outperforming BTC by 4.4%. Peter Thoc, founder of House of Crypto, describes the current setup as a “perfect asymmetry window,” where small, high-risk allocations could produce outsized returns. Market strategists see Ethereum’s surge as the likely precursor to wider altcoin gains if liquidity and technical conditions continue to align.
