Zcash (ZEC) has experienced a remarkable 600% increase in value over the past 30 days, climbing from $54 to approximately $372. This surge is attributed to growing interest in privacy-centric cryptocurrencies and the upcoming halving event on November 18. The price rally has pushed ZEC beyond its 2021 high, although it remains below its 2016 peak. The rally is driven by several factors, including heightened privacy concerns and endorsements from prominent investors. Additionally, Grayscale's move to allow qualified investors access to ZEC tokens has contributed to the momentum. Despite the impressive gains, experts warn that the surge is speculative, with limited growth in shielded transactions, and its sustainability will hinge on post-halving market sentiment and actual user adoption.
