Ethereum did not follow the major trend yesterday. Instead, it oscillated downward throughout the day. After dropping to the 2061 region last night, it found slight support and then oscillated up and down until this morning when it faced pressure again around 2100. On the 4-hour chart, it is oscillating in a narrow range above the midline as support. Although it has not broken the midline in the short term, the rebound momentum is clearly weakening. Pay attention to the 2100 level during the day. If it doesn't break, you can short near this region, with targets looking at the 2050-2000 zone.
