12.30 Tuesday noon, Bitcoin surged past 90,300 on the Silk Road chart and quickly fell back to around 86,800, once again playing out a double kill scenario. However, those who paid attention early should have smoothly navigated this wave of market movements. From the current market situation, after a period of sideways adjustment, all technical indicators have now recovered. The MACD indicator's red bars are shrinking, and the KDJ indicator has turned upward and formed a golden cross. The overall strategy today remains focused on buying dips. Personal advice, for reference only (strictly set stop-loss): Bitcoin can be bought around 86,800-96,000, with targets of 88,500-89,500.
