Bitcoin last night dipped to a low of 91200. The short positions laid out at 94000 yesterday successfully reached the first target around 91800. Subsequently, the price experienced a V-shaped reversal, surging again towards the 93500 range. This oscillating pattern reminds people of the 88000 wave, with various reverse breakouts, and market sentiment has indeed been somewhat volatile. However, the current rebound has gradually pushed prices higher, providing an opportunity to short at higher levels. If the upward movement continues, there is still a window to enter short positions at high levels, and close attention should be paid to the resistance around 93500-94000.
