Bitcoin dipped to around 65,600 in the early hours yesterday and then rebounded strongly. The market continued to rise during the daytime, reaching a high of around 69,500 before encountering resistance and pulling back. Currently, it is consolidating around 68,500; the four-hour rebound momentum has weakened. The 69,500-71,000 zone forms a strong resistance area, indicating a short-term correction may be needed. Key support levels to watch are between 66,500 and 67,000. If these can be held effectively, there is still potential for the market to continue rebounding and test higher levels again. However, if support is broken, beware of a second bottom risk. Trading should be approached within a range, with strict risk management.
