On-chain data shows that a well-known swing trading whale, nemorino.eth, began gradually accumulating positions in mid-November last year. Over more than two months, they bought a total of 9,043 WETH, with an average price around $3,085. From the end of last year to mid-January this year, this position looked quite profitable—unrealized gains even reached $2.87 million, almost ready to be cashed out for a big profit. But what happened? During the recent market correction, the whale couldn't hold on and hurriedly sold 3,000 WETH 12 hours ago to cut losses, resulting in only $30,000 in profit. Currently, they still hold over 4,089 WETH, with unrealized losses expanding to $472,000. The reversal from paper gains to losses in this trade highlights the market's unpredictability—sometimes you get the direction right but choose the wrong timing, ultimately ending up with less than you started.
