According to @BitMEXResearch, more than 82,300 ETH from The DAO refunds remain unclaimed (about $375 million) plus over 70,000 ETH in the Extra Balance contract (about $322 million), based on the Etherscan contract data referenced in the post (source: @BitMEXResearch; Etherscan). @BitMEXResearch also reports roughly 1.3 million Ethereum Classic (ETC) from the same legacy claims remain unclaimed (source: @BitMEXResearch). The concentration of these dormant balances is material for on-chain monitoring, and traders can track the DAO refund and Extra Balance contract addresses highlighted in the post for any large movements (source: @BitMEXResearch; Etherscan).

According to @ai_9684xtpa, an ancient Ethereum whale who participated in the Ethereum ICO by acquiring 310,000 ETH has transferred 4000 ETH, worth $9.33 million, to Kraken seven hours ago, suggesting a potential sell-off. This whale was also involved in the 2016 DAO refund event, receiving 100,000 ETH from the refund contract, worth only $1.28 million at that time. The address still holds 19,679 ETH, approximately worth $45.12 million.
