Ethereum is currently in a downtrend channel. Although it is now above an uptrend line, the rebound is weak and the current movement is very similar to the previous drop from 3300 to 3000. Only by breaking through this downtrend channel and not breaking below the trend line can we look up to the short positions above at 2160-2220, 2297-2314, and 2357-2388. You can adopt a strategy of adding positions in batches. For going long, you can focus on 1920 to bet on a rebound, but you must set a good stop loss. If it breaks below the last uptrend line and fails to retest above it, you must stop loss.
