According to Ai 姨 (@ai_9684xtpa), a major Ethereum whale has shifted strategy by closing a 4,000 ETH short position and subsequently purchasing 7,289 ETH on the spot market for approximately $13.2 million at an average price of $1,826. This aggressive position reversal signals renewed bullish sentiment from large holders, and such whale accumulation often precedes increased volatility and potential price rallies in the short term. Traders should closely monitor on-chain whale activity and spot market flows for ETH price momentum cues (Source: Twitter/@ai_9684xtpa, April 28, 2025).
