The key drivers for Ethereum (ETH) breaking through 2500 USD include technical upgrades, market sentiment, and ecological development. The Pectra upgrade (completed in March 2025) significantly enhances network scalability and user experience by improving staking efficiency (increasing the validator cap from 32 ETH to 2048 ETH), optimizing Layer 2 performance (doubling blob capacity), and introducing multi-currency gas payments, attracting institutional funds. Technical analysis shows that after ETH stabilizes above 2500 USD, it forms an 'ascending triangle' pattern, with historical trends suggesting a potential increase of 30%-50%, targeting 3000 USD. On-chain data indicates that whales are accumulating and the staking rate is only 22%, suggesting future demand may double. Furthermore, the Bitcoin halving effect and expectations of Federal Reserve interest rate cuts provide liquidity support for the crypto market. In the short term, attention should be paid to whether 2500 USD can convert into a support level, while long-term prospects depend on ecological breakthroughs (such as DeFi 2.0 and ETF expectations).
