Four elements to identify the bullish return:
1. Bull species: must have been a big bull coin, a leading coin, a dark horse coin, etc.
2. Full adjustment. After the first wave of the market ends, it must undergo full adjustment. This coin is divided into two layers: one is long enough, and the other is large enough
3. Stabilization: There must be a certain stabilization trend or obvious signal
4. Shrinkage: Whether the adjustment is in place, in addition to space, there is also volume. If the dealer washes the market until all retail investors leave, the volume will shrink
