Yesterday, the daily line closed negatively. The big cake performed relatively strongly in the rebound, but the process of stepping back was not large. Yesterday, the highest was close to 58,000 points, and the strength of the stepping back did not reach 10 percentage points. The lowest was only 54,600. It did not fall below the support position of 54,000 points. The market returned to the 56,000-58,000 range. The strength of the rebound was relatively weak yesterday. It fluctuated for more than 100 US dollars in the high range of 2420-2550. It fell below the 2400 point line at the lowest point of 2300 points in the early morning, and it still showed a weak performance. Just now, the big cake rebounded by more than 2,000 US dollars, which was also a matter of a moment. At the current stage, the volatility after the sharp drop in the market is still relatively large for the current price, especially the back-and-forth volatility. Be sure to control the risk and be careful of temptation. It is recommended to operate at high altitude.
