Recently, the price of Ethereum ($ETH) has shown a significant rebound, and market sentiment is gradually warming up. This rebound is mainly driven by multiple positive factors. First, the Ethereum network is about to welcome the 'Merge' upgrade, a major technological transformation that will shift it from proof-of-work (PoW) to proof-of-stake (PoS), significantly reducing energy consumption and enhancing network efficiency. The market's expectation for this upgrade has restored investor confidence.

Secondly, the overall warming of the cryptocurrency market has also driven the rise of $ETH. The rebound of mainstream coins such as Bitcoin ($BTC) has provided support for Ethereum, and market risk appetite has increased. In addition, the continuous development of DeFi (decentralized finance) and NFT (non-fungible token) ecosystems has brought more application scenarios and demand for Ethereum.

On the technical front, after stabilizing near key support levels, $ETH has gradually broken through short-term resistance levels, showing strong upward momentum. Market analysis suggests that if $ETH can hold above key levels, it is expected to rise further. However, investors still need to be cautious of market volatility risks, especially in the context of ongoing macroeconomic uncertainty. Overall, Ethereum's rebound reflects the market's recognition of its long-term value, but short-term trends still require close attention to market dynamics and technical indicators.
