According to @EmberCN, a well-known Ethereum whale who previously shorted $4,000 ETH at $1,808.6 has reversed their position within the last 30 minutes. The trader closed the short at $1,821.7, incurring a $50,000 loss, and immediately went all-in long by converting $13.3 million USDC to purchase 7,289 ETH at an average entry of $1,825.8. This large-scale position switch signals a significant sentiment shift and could influence short-term ETH price volatility. Traders should monitor ETH price action closely for potential bullish momentum triggered by such whale activity. (Source: @EmberCN Twitter, April 28, 2025)
