This idea will be invalid if Bitcoin break support around 35k zone. But as long as Bitcoin doesnt break the support, most likely one more last dump may happen.
Beside if we are looking to the volume, most likely bottom its near. Possible if the bottom already in at 29k zone or like I said one more dump to 23k zone. If we arrive later at 23k zone we may have v-shape recovery, due to a lot of short need to be close.
