Recently, a large-scale trader (commonly referred to as a 'whale') deposited 25,800 Ethereum (ETH) into the world's leading digital currency trading platform, Binance, with a total value of approximately $87 million. This move has drawn significant attention from the market. The whale's operations over the past two months have demonstrated their sensitivity and influence on market trends. Between May 31 and July 25, this whale withdrew 26,721 ETH from the Binance platform when each ETH was priced around $3,457. This suggests that during this period, the whale may have conducted large-scale cashing out or adjusted its asset allocation. However, on July 17 and 29, the whale deposited 26,660 ETH into other exchanges (CEXs), at which time the price of each ETH had fallen to $3,376. These series of operations suggest that the total loss for the whale during the period of Ethereum price fluctuations is estimated to be about $2.16 million, or approximately -2.34%. These data and events remind investors that the behavior of large traders has a significant impact on market volatility and is worth close monitoring.
