The Ethereum (ETH) investment circle has been shaken once again as a large investor who has been active since 2018 recently completed a striking transaction. This investor purchased 1,550 Wrapped Ether (WETH) at a price of $2,285 each on June 23, and has now closed all positions, totaling a profit of up to $3.211 million.

The wallet address of this investor starts with 0xF89...8AEfe and is referred to by industry insiders as a 'swing whale'. According to statistics, over the past four years, this investor has conducted a total of four swing trades in Ethereum, with a cumulative profit of an astonishing $3.739 million.

This transaction has sparked speculation in the market about the short-term trend of Ethereum. Some analysts believe that when seasoned investors start to cash out on a large scale, it may signal the end of the current upward trend. However, there are also viewpoints that suggest the actions of a single investor are not enough to sway the direction of the entire market, and investors need to consider multiple factors comprehensively.

In any case, this transaction once again proves the high-risk, high-reward nature of the cryptocurrency market. For ordinary investors, this is both an opportunity and a warning: in this fast-changing market, professional knowledge, risk awareness, and timely market insights are all indispensable.
