Bitcoin has entered a good short-selling window in mid to late January. Currently, the price is around 94,000, which can serve as an entry point for shorting. Based on technical analysis, within approximately a 10-day cycle, the price is likely to retrace to the 88,000-90,000 range, where the upward trend initially started. Calculated this way, a single trade could yield a profit of 5,000 points, which is quite substantial for medium-term trading. To seize such opportunities, the key is to accurately grasp the price levels and timing.
