Behind today's sharp decline, the main reason is to liquidate the long positions of two whales, with liquidation points concentrated around 4220. As the whales are forced to reduce their positions and close their trades, the market releases short-term risks, and the price has temporarily stabilized around this level. I opened a short-term position and gained more than double the floating profit. Now the key is whether it can maintain the range; if it can hold, there may still be upward opportunities. Don't forget, the early morning Tep meeting may add more sparks, and the volatility risk cannot be ignored. $ETH
