Why is the sharp decline in low-level shrinkage one of the signals of an upward turn in speed?

First of all, you must know that shrinkage not only means a decrease in transaction volume, but also represents consistency and unity.
The literal meaning of shrinkage and large decline is to use a smaller transaction volume to create a larger decline, which means that there is no difference in the transaction volume, and it is mostly selling orders or all selling orders, which can lead to a large decline.
Then when the currency price is already at a relative or absolute low, the phenomenon of unified selling occurs. In addition to the sudden strong bad news, it is very likely that the bankers will hold the retail investors hostage and release the last excess floating chips. Only after cleaning up can the bankers pick up again. Lower-priced chips enter the market.
