The long lower shadow on the daily chart of Bitcoin indicates strong buying support below. In the short term, the 1120-1135 range has formed effective support, but overall it is still under pressure from the 5-day moving average, and the daily MACD bearish pattern remains unchanged. Although there are signs of partial stabilization on the 4-hour chart, the rebound strength is weak, and the MACD dual lines are flat below the zero axis, suggesting a possibility of maintaining low-level fluctuations in the short term. In terms of operations, it is advisable to primarily focus on short selling during rebounds. Bitcoin can be lightly shorted near 1145-1150, with a stop loss above 1160 and a target of 1130-1135. For Ethereum, pay attention to the pressure around 3640-3660; if it faces resistance and falls back, a short position can be attempted, with a stop loss at 3680 and a target of 3580-3600. Short-term trading requires caution against the risk of a rebound after excessive declines.
