With the cryptocurrency trading at $4,590, the price hovered near critical technical levels, including immediate resistance at $4,640 and support at $4,535.

Deribit data showed Ethereum’s price could consolidate near $4,500 as contracts expired at 8:00 UTC. However, analysts noted that Ethereum’s accumulation by large holders—approximately 820,000 ETH ($3.8 billion) purchased in three days—suggested institutional confidence.

Technical indicators pointed to a potential breakout if Ethereum cleared $4,765, the upper boundary of an ascending triangle pattern formed since July.

Meanwhile, the SEC’s ongoing regulatory overreach and the broader crypto market’s sensitivity to macroeconomic shifts underscored the sector’s volatility as it navigated a rapidly evolving landscape.
