According to @EmberCN on Twitter, Vitalik Buterin recently purchased 205.5 ETH using 317,000 DAI and 33,000 UNI, then transferred a total of 693.9 ETH (worth $1.83 million) and 340,000 USDC via the privacy protocol Railgun from address 0x1810. This notable on-chain activity suggests potential bullish sentiment from a key Ethereum founder and highlights increasing use of privacy tools by major crypto figures. Traders should closely monitor ETH price action and Railgun transaction volumes as these movements could impact short-term market liquidity and signal institutional-grade interest in privacy protocols (Source: @EmberCN, Twitter, June 4, 2025).
