In the cryptocurrency market, there are two highly representative price trend characteristics: the first is characterized by a rapid rise followed by a gentle retreat, then a strong rebound, forming a cyclical price upward movement. This type of trend is often a significant signal that the market is in an upward trend; the second presents a cliff-like sharp drop followed by a brief technical recovery, and then another significant decline. This repeated oscillating downward pattern is typically a sign of major funding selling off and conducting panic selling operations.
