According to Lookonchain, a trader known for making impulsive decisions recently bought 1,805 ETH for $6.42 million at a price of $3,559 each. However, two weeks ago, he panic sold at a significant loss of $3.6 million. With the ETH price rising, he repurchased 1,734 ETH for $3.11 million at $1,792 per coin. This highlights the risks of emotional trading and the classic buy high, sell low pattern.
