On June 4th, according to EmberCN monitoring, out of 693.9 ETH transferred by Ethereum co-founder Vitalik to Railgun in the past half hour, 205.5 ETH were purchased by Vitalik using 317000 stablecoins DAI and 33000 UNI. Vitalik, as a co-founder, obtained a large amount of ETH in the early stages of Ethereum, and many of its donations came from these holdings rather than market purchases. This transfer is a rare occurrence for Vitalik to use USDC and UNI to purchase ETH.
