最新报道:Ethereum spot ETFs launched in July 2024 have attracted billions in institutional inflows by Q3 2025, with CoinShares reporting $646 million inflows in one week alone. While ETFs provide passive exposure, Layer-2 networks like Arbitrum ($19.1B TVS), Base ($14.5B), and Optimism ($3.1B) now handle over 70% of Ethereum's DeFi activity. Protocol upgrades including EIP-4844 have reduced transaction costs, with VanEck projecting L2 networks could reach $1 trillion valuation by 2030 as institutions shift from passive holding to active ecosystem participation.
