CoinMeta data: According to Bloomberg, the privacy coin Zcash ( ZEC ) has risen by about 3000% since mid-2025. The Gemini founder, Winklevoss, and the DCG founder, Barry Silbert, are increasing their focus on mining and investment products related to Zcash. The Cypherpunk Technologies supported by Winklevoss has already secured approximately 20% of the total network computing power, while the Fortitude Mining supported by Silbert plans to increase its share of computing power to around 20%. The Grayscale under their umbrella launched Zcash ETF in August, and Winklevoss also applied to launch a similar product in October. Reports suggest that concerns regarding chain privacy brought about by AI technology have led to Zcash regaining market attention, but issues such as concentrated computing power, protocol security vulnerabilities, and regulatory risks remain potential challenges.
