According to @ai_9684xtpa, an ancient whale deposited 4,000 ETH worth $9.33 million to Kraken 7 hours ago, which was suspected to be sold. The whale participated in the DAO refund event eight years ago and received 100,000 ETH distributed by the refund contract on July 24, 2016, which was only worth $1.28 million at the time. The current operating address still holds 19,679 ETH, about $45.12 million.
