At present, the Big Dipper is oscillating at a high level around 73K, and is at the end of the macro downward trend line and the convergence of the bottom box. The next one to two weeks will be the absolute turning point that determines the medium-term direction. From the perspective of weekly level structure, the chips in the bottom 60K to 75K range have undergone long-term turnover, and the current price is extremely close to the resonance resistance zone between the upper edge of the box and the long-term suppression. At this position, it is difficult to form an effective breakthrough solely based on the amount of field memory, and the key winning and losing hand lies in the overflow of US stock liquidity. 75K: Strong pressure breakthrough zone. If the weekly solid holds steady, it confirms a reversal. The first target above is directly at 85K. 73K: The current price is in the middle zone of extremely poor profit and loss ratio, and it is important to avoid playing games on the left side of heavy positions here. 65K: The first support axis for resistance and decline, with a maximum defense of 60K in case of panic and sell-off. Based on the recent trend of the US stock market, if the high sentiment of chasing risks is maintained, it will directly help BTC to break through the suppression by increasing volume; If there is profit taking or correction in the US stock market, it is easy to form a bearish trend or a long upward shadow false breakthrough, and follow to find bottom support. At this position, do not guess the size, only deal with it. The right-hand thinking is dominant: break through, reverse and follow the trend to buy more. If encountering obstacles, lightly test the short position and continue to oscillate back into the box.
