Bitcoin is currently in a resistance zone in the daily time frame(30183.33~29967.48), which has caused a sharp drop in the past, and can cause a price drop again. But you should look for confirmation before thinking about the sell position in smaller time frames And in the time frame of 15 minutes, it is in a triangle, if it breaks the support area of 29,800 downwards, a sell position can be taken, and if it breaks the triangle upwards, it can take a risky buying position.
