Vitalik Buterin, the co-founder of Ethereum, transferred 400 ETH to Coinbase on September 24, 2023. This is part of a larger trend of Buterin moving ETH to mainstream exchanges over the past 10 days, with a cumulative total of 2,421 ETH transferred. The reasons for Buterin's transfers are unknown, but some speculate that he may be selling ETH to fund other projects or to simply diversify his holdings. Others believe that he may be preparing for a major ETH price movement. Whatever the reason, Buterin's transfers are a sign of the growing popularity of ETH and the increasing institutional adoption of cryptocurrencies.
