$ETH Ether fell back after the top yesterday. This fall has temporarily evolved into a large-cycle oscillating downward trend. Whether this decline can return to 3449 in the past two days is critical. If it returns to 3449, the daily central axis will be out, and it will rise again at any time (as shown in the green line). If it does not return to 3449, the 26/52 moving average position on the 4-hour chart may become the position to stop the decline. This is a strong approach, and the rise will be advanced.
