When the crypto market was feeling the pain again and ETH prices experienced a significant correction in February, a familiar but always arousing news hit the screen: Vitalik Buterin was selling ETH again.In the past four days, the wallet of the father of Ethereum sold 4,326 ETH in batches through decentralized trading protocols such as CoW Swap, equivalent to US$8.12 million.Combined with previous data, more than 11,000 coins have been sold since the beginning of February, amounting to US$22.78 million.Many trading enthusiasts suddenly felt FOMO - "The founders are selling, is it time to run away?" But looking at it calmly, this is by no means an "exit signal".Every public action taken by Vitalik is highly transparent and forward-looking.As early as January 30, he made it clear in a post that the Ethereum Foundation will enter a period of "mild austerity" (mild austerity) to free up resources for the next five years to sprint towards the core roadmap. He himself will personally undertake some of the "special projects" that were originally responsible for the foundation. For this purpose, he will withdraw 16,384 ETH from the wallet and gradually deploy it to key areas such as open source software, security privacy projects, and full-stack verifiability.The sales of the past four weeks are the orderly execution of this long-term plan.In the Web3 world, Vitalik has never been a simple "big player in the currency circle", but a thought leader who has led the narrative since the 2014 white paper era.His currency selling behavior has always served ecological construction, from funding Gitcoin public products in the early days to supporting privacy and scalability research and development today.Today, let’s break down the ins and outs of this sale and see how it intersects with Ethereum’s major upgrades such as Glamsterdam and Hegotá in 2026, and what it means for ordinary traders, DeFi enthusiasts and meme currency players.
