The optimism surrounding Ethereum in the cryptocurrency market, spurred by the introduction of Spot Ethereum ETF funds, has waned due to recent decisions by the SEC. Consequently, Ethereum's upward trajectory has been hindered, with the $4,000 resistance level proving to be a significant obstacle.

Analyzing Ethereum's chart, we observe a pattern of a rising channel that initially broke through the resistance line with the introduction of ETF activity in late February. However, recent events have caused Ethereum's price to lose steam, retracting it back into the formation zone. Currently, the EMA 9 (blue line) is acting as a barrier, indicating a negative outlook for Ethereum's short-term performance.

Key support levels to monitor for Ethereum on a daily basis include $3,274, $3,149, and $3,030, respectively. A daily close below the critical support level of $3,274 could signal a further loss of momentum for Ethereum's price. Conversely, important resistance levels to watch are $3,420, $3,664, and $3,931, with a daily close above $3,420 potentially reigniting positive momentum for Ethereum.

Turning to the ETH/BTC chart on a weekly basis, we observe a pattern of a falling channel formation, indicating Ethereum's depreciation against Bitcoin. Despite initial gains following ETF news, the ETH/BTC pair has remained within the formation zone, suggesting a continued decline in Ethereum's value relative to Bitcoin.

On the weekly ETH/BTC chart, significant support levels include 0.04806 BTC, 0.04598 BTC, and 0.04321 BTC, respectively. A weekly close below the crucial support level of 0.04806 BTC could signify further devaluation of Ethereum against Bitcoin. Conversely, notable resistance levels are 0.04981 BTC, 0.05178 BTC, and 0.05510 BTC, with a weekly close above 0.05510 BTC potentially indicating a reversal in Ethereum's value.

In conclusion, Ethereum's price momentum has slowed down in both the broader cryptocurrency market and in comparison to Bitcoin. Key support and resistance levels should be closely monitored to gauge Ethereum's future trajectory.
