ETH Dominance Stabilizes at Key Level with Positive Momentum Indicators
Ethereum's proportion of the total cryptocurrency market capitalization has maintained a crucial support zone, according to charting data shared by X user JamesEastonUK. TradingView data illustrated that ETH dominance stabilized near its mid-range following a significant rebound from early 2025 lows. The price structure remains positioned above a long-observed horizontal support level.
Concurrently, momentum indicators have shown a positive shift. The MACD on the ETH dominance chart has turned bullish, signaling an increase in trend strength after an extended period of negative readings. Additionally, the histogram bars have expanded, reflecting improving momentum rather than a stagnant or declining trend.
Furthermore, trading volume has increased in correlation with the recent upward price movement. This rise suggests broader market participation as ETH dominance has recovered from the lower band indicated on the chart. Consequently, Ethereum's market share was holding steady around 12.5% at the time of the analysis, successfully preserving the key support level while technical signals aligned favorably for an upward trajectory.
