When will ETH break through $4000? This question reflects the development potential of the Ethereum ecosystem and market expectations. From on-chain data, ETH's activity level and ecosystem applications are continuously expanding, with DeFi, NFT, and Layer 2 solutions all contributing to ecosystem value. Technically, the $4000 level corresponds to a pressure point near historical highs, and breaking through requires sufficient momentum. Market participants are generally focused on the progress of Ethereum upgrades, Federal Reserve policy trends, and institutional entry. In the short term, attention is mainly on macro liquidity and Bitcoin's driving effect; in the medium term, the core factors driving long-term growth are Ethereum's own technical improvements and application innovations. The current price level is relatively reasonable, and patiently waiting for the market to give an answer may be a wiser approach.
