There is evidence suggesting that the cryptocurrency market has price cycles. The cycle length is not fixed but is generally believed to be around 4 years, similar to Bitcoin's halving cycle. During the upward phase of the cycle, prices rise as more investors enter the market, driven by factors like technological innovation, increasing adoption, and positive regulatory news. In the downward phase, prices decline due to factors such as market corrections, regulatory crackdowns, and a decrease in market sentiment.
