Are crypto assets fair value?

Could you elaborate on the concept of "fair value" when it comes to crypto assets? How do we determine if a cryptocurrency is fairly priced, given the high volatility and lack of fundamental metrics like earnings or dividends? What factors should investors consider when assessing the potential value of a crypto asset, and how do these factors differ from traditional asset classes? Is there a way to predict the future value of a crypto asset, or is it purely speculative?
