August 20th, Wednesday afternoon ETH analysis:

From the one-hour level, the ETH moving averages show a bearish arrangement, forming a strong upper pressure zone, which significantly restricts the price upward. In terms of the MACD indicator, the current expansion of the red bars is limited, and this rebound is more of a weak adjustment during the downward process, rather than a signal of a trend reversal to the upside; subsequent upward momentum is expected to be insufficient.
The 4060 line below is the key support level in the recent period, and attention should be paid to its defense situation. If this position is effectively broken, the price may experience an accelerated downward trend.

Personal suggestion (strictly set stop loss):
You can place short positions in the range of 4200-4230.
The target first looks at 4100, further can look at 4030.
