What drives crypto prices up or down?

Could you elaborate on the key factors that typically drive the fluctuation in cryptocurrency prices? I'm curious to know if market sentiment, regulatory changes, or technological advancements play a significant role. Additionally, how do global economic conditions and geopolitical events influence these digital assets? Are there any specific indicators or metrics that investors should keep an eye on to gauge potential price movements? Understanding these dynamics would help me make more informed decisions in the crypto market.
