Brief opinion: The aggressive short action of whales on ETH with 25x leverage indicates strong confidence in a short-term price decline, but also highlights the high volatility risk that could trigger a domino effect in the crypto market. Although the temporary profit reached $638K (total $804K including SOL and ENA), retail investors should hold while monitoring key support levels, avoid FOMO, and apply strict risk management to anticipate sudden reversals. This is not a mass sell signal, but a reminder that the market is dominated by big players.
