The red circle is just around the 30% retracement from the highest point;

The median of the green circle is around 42,000. Many people see the number starting with 4, which is the support level (called the pressure level by some people at that time). The transactions here are very dense, belonging to the dense transaction area, and will also be the support range for some time in the future (bull market). But I think it is too pessimistic to see the decline here now.
