Yesterday, Bitcoin faced resistance around 91,900 and managed to break through. From the high to the low, the entire decline was well-controlled, with the lowest point touching the 90,000 level, capturing an almost 1,900 to 2,000 point range before and after. This analytical approach has been validated continuously for a week, with very accurate timing. Interested friends can compare it with recent market records; data doesn't lie. Currently, this precise ability to identify resistance levels is still meaningful for short-term trading.
