Ethereum (Ether) has surpassed the $4,000 mark for the first time since December 2021.

The surge is partially attributed to the anticipation of the Dencun upgrade and the possible approval of an Ether ETF by the SEC.

Ethereum's ecosystem, which supports smart contracts and decentralized applications, is a key factor in its revolutionary impact on internet applications.

Technical analysis shows potential for continued growth according to daily chart indicators, while weekly charts advise caution due to potential volatility.

The approval of an Ether ETF could lead to significant capital inflows and bolster institutional interest in Ethereum.

Long-term expectations for Ethereum remain positive, with predictions of a continuing uptrend amidst increasing institutional engagement and a generally bullish cryptocurrency market.
