On August 3, Ethereum's price fluctuated between $3340 and $3450, with a daily low of $3350. The rebound is weak, and the technical outlook remains in a downtrend channel.

From a technical perspective: the price in the four-hour cycle is at the lower Bollinger Band, MACD bearish momentum is strengthening, RSI is below 40, and there is insufficient rebound momentum in the short term. The first resistance level above is at $3450-3480, with strong resistance at $3525. Short-term support is at $3320-3350, with key support at $3240. If it breaks below, it may drop to $3100.

Short position operation range suggestion: Short when rebounding to the $3440-3460 range, with a stop loss at $3500 and a target of $3,380-3350.

Long position operation range suggestion: If the price quickly drops and stabilizes around $3320, a light long position can be tried, with a stop loss at $3280 and a target of $3400-3450.

Market risks and key points: New tariffs effective on August 3 may trigger global market fluctuations, so attention should be paid to the safe-haven correlation between Bitcoin and gold. The July PCE price index will be announced on August 23; if inflation exceeds expectations, it may strengthen a hawkish stance, negatively impacting the crypto market.

Current operational advice is to focus on short positions, avoid blindly bottom-fishing, and strictly adhere to stop-loss discipline. Monitor macroeconomic data and on-chain whale movements, and adjust strategies flexibly.
