Grayscale CEO Peter Mintzberg said on X that the Zcash ETF, ZCSH, has tripled its assets under management since its Aug. 25 launch, local time. He said rising investor interest in privacy-focused assets has also increased demand for ZEC-related investments. Mintzberg said ZCSH became the first altcoin exchange-traded product to exceed $1 billion in assets under management during its first month. Grayscale currently holds 550,000 ZEC.
