What DeepSea's data shows
DeepSea tags large, active traders as sharks and gives some an automatic name. It calls this address Hold1f17. Its realized profit table counts closed trades only, matched first in, first out, with one row per chain.
Built at 6:33 a.m. ET, the 7-day rows were: BNB Chain minus $702,732 (7 of 32 trades won), Ethereum minus $423,737 (3 of 33), Optimism minus $57,899 (1 of 4) and Base minus $20,938 (3 of 7). Over 30 days the four rows total minus $2,350,163 on 233 trades, 80 of them winners.
DeepSea's 24-hour flow view lists the address on Optimism with $0 bought and $1,360,091 sold in 2 trades. The view does not name the token for that wallet.

The Optimism sale
Two trades worth $1.36 million average about $680,000 each. Among sharks that only sold in the last 24 hours, the next biggest was about $125,000. The sale has not yet shown up as a closed result in the 7-day Optimism row, which still reads minus $57,899 on 4 trades.
Sharks were net sellers of OP, Optimism's own token, in the same window: $4.61 million sold against $2.39 million bought. DeepSea does not tie the 1f17 sale to a specific token, so we cannot say it was OP. At 7:00 a.m. ET CoinGecko showed OP at $0.0949, down 5.4% in 24 hours and 14.6% in 7 days.
Market backdrop and limits
This analysis uses data from DeepSea and CoinGecko. Ether was at $2,020.24 on CoinGecko at 7:00 a.m. ET, down 16.4% in 7 days. Who controls the 1f17 address is unknown. Realized profit ignores tokens still held, so the wallet's full result may be better or worse.
LC Insight analysis
This section is our reading of the facts above, not a statement of fact.
- We think the spread of the losses is the point: the address shows realized losses on every chain it trades this week, and its latest move was a sale with no buy.
- The BNB Chain loss grew by almost $280,000 in six hours, so the 7-day figure can change fast for this wallet.
- Without the token name, the Optimism sale is a size signal only. It should not be read as a vote on OP.
What's next
- Whether the $1.36 million Optimism sale turns into a closed loss or profit in DeepSea's table
- Whether the BNB Chain loss keeps growing
- Where the sale proceeds move next
