Ether's rebound after Monday's opening was somewhat beyond expectations, reaching a peak above 4200 during trading hours before oscillating back. Currently, a continuous bearish trend has emerged on the four-hour chart. This evening, attention should be paid to the support strength around 4100; if it is successfully broken, Monday's rebound will essentially conclude. There has not been much long positions with higher trade volumes during the day, so we'll continue to observe a wave of four-hour pullback this evening.
