DEV Sell? Don't panic! Let me break it down for you; this is actually a clear separation of finances and responsibilities. I. The Overlooked Signal of "Budget Tightening" Vitalik had clearly foreshadowed several days ago that the Ethereum Foundation (EF) would enter a "budget tightening period." This doesn't mean Ethereum is running out of funds, but rather a strategic reallocation of resources. EF's strategy is clear: tighten its grip and concentrate limited resources on critical core areas, such as the implementation of zkEVM and research into quantum-resistant cryptography. II. The "Great Shift" of 16,384 ETH To achieve EF's "slimming down" without slowing it down, Vitalik adopted a rare "personal pressure" approach. He requested to withdraw 16,384 ETH as a separate budget—the source of the recent frequent on-chain fund changes. Conclusion: The current ETH sale is a necessary liquidity exchange to pay the salaries and R&D costs of relevant developers. From a financial auditing perspective, this is a pre-planned "scheduled expenditure" rather than a sudden "founder's share reduction".
