Bitcoin can reach 83300. If it breaks this resistance and rebounds, we will then look at the area around 84000. If it can rebound to around 84000, pay attention to the four-hour closing situation. If the four-hour closing breaks 84000, the market has a chance to rush towards 85000 and 85500 in this range. For a steady approach, try short orders in this range, while aggressive shorts should be placed near 84000. If the four-hour closing needs to break 84000, this short order should be exited manually. If the night rebound can't even push past 83300, the market will continue to dip.
