According to on-chain analyst Ai Yi, Ethereum co-founder Jeffrey Wilcke deposited another 9,840.36 ETH, worth approximately $41.33 million, to Kraken after a three-month hiatus. In May of this year, he deposited 105,700 ETH to Kraken and distributed it to eight new addresses. In the past hour, one of these addresses began transferring ETH back to an exchange, presumably in preparation for a sell-off. The current value of this batch of ETH has increased from $262 million to $442 million.
