Currently, the monthly support level is around 57,000. This month, there was a bottoming out and a rebound, with the range between 71,000 and 73,000. If it approaches 57,000, you can allocate 50% of your spot holdings. If it continues to decline, leaving room for additional purchases, you can add in two stages, each 25%. The specific interval could be 5,000 or 10,000 points; observe as it moves. The key is that you are buying near the almost lowest point, not the highest. The estimated bottoming out time is around March 15. Even if you reduce your holdings near 71,000-73,000, there will be a retracement, but it won't break the previous low. This is the investment logic for the upcoming cycle, which could be 3-5 years. My personal reference is to even allocate 10% of the principal to spot holdings, because their profitability exceeds expectations!!!
