Ethereum is steadily gaining ground as Bitcoin’s dominance continues to decline, signaling a quiet shift in market power. As ETH captures a larger share of the crypto landscape, key support and resistance levels are now in focus, pointing to potential for further upside.Ethereum Captures Larger Market Slice as BTC WeakensIn a recent update on X, The Boss pointed out that Ethereum’s dominance in the crypto market is steadily increasing, aligning with previous expectations. As Bitcoin dominance begins to slip, Ethereum is gaining momentum, gradually capturing a larger share of the total market capitalization. This shift highlights the growing confidence in Ethereum’s relative strength compared to Bitcoin under current market conditions.The Boss also emphasized the technical significance of a green line marked on the dominance chart, identifying it as a key support zone. As long as Ethereum dominance remains above this level, the bullish outlook remains intact. This support has previously acted as a reliable floor during past consolidations, and holding above it could provide the foundation for further gains in dominance.Attention is now turning to potential resistance zones, which The Boss illustrated using yellow lines derived from Fibonacci retracement levels. These levels represent likely areas where ETH dominance could face selling pressure or hesitation. However, surpassing them could indicate further strengthening of Ethereum’s position in the market.Overall, The Boss’s analysis suggests that the decline in Bitcoin dominance may be fueling Ethereum’s rise, and the technical setup remains favorable for ETH as long as it stays above the highlighted support. ETH Eyes Key Resistance Zone At $3,900 Within Rising ChannelThomas Anderson recently shared his analysis of the ETHUSD H1 chart, observing that Ethereum was trading at $3,851.25 and approaching a key resistance zone between $3,876 and $3,900. Price action is unfolding within an ascending channel, with the upper yellow line marking a critical resistance area. He further noted that the 200-day moving average, represented by the red line on the chart, is offering dynamic support around the $2,900 level. This moving average has played a crucial role in sustaining the uptrend and remains an important level to monitor in case of a retracement. The analyst highlighted that Ethereum is now testing the upper boundary of a larger ascending channel, with the $3,287.74 level acting as a solid support zone in the 4H context. Anderson emphasized that this level has served as a major floor during recent consolidations, indicating that any near-term pullback may stabilize there. While the trend remains bullish, ETH could face a temporary dip at current levels before a sustained breakout above the $3,900 area.
