Wallet 0x69A8 received about $13.62 million from a sale of 6,532 Ether (ETH); the $3.1 million loss estimate covers only an earlier 5,105-ETH purchase.
The sale price averaged $2,085 per ETH. Roughly one month earlier, the wallet acquired 5,105 ETH at an average price of $2,691 each.
Comparing the $2,691 purchase average with the $2,085 sale average gives a $606 gap per ETH, or about $3.09 million across 5,105 ETH, rounded to $3.1 million. The wallet sold 1,427 more ETH than it had bought in that earlier transaction; those additional coins are outside the loss estimate.
