Grayscale says ZEC mining rewards top BTC by 2x per machine, 4x per MWh

Grayscale said a recent rise in Zcash (ZEC) prices has sharply improved mining profitability, driving up mining activity and strengthening network security, Wu Blockchain reported. Grayscale said a single ZEC mining machine now generates about twice the daily mining reward of a Bitcoin mining machine, while revenue per megawatt-hour is about four times higher than Bitcoin on a power-efficiency basis. The firm added that Zcash and Bitcoin mining hardware are not interchangeable, so the comparison does not reflect the same machine model. Based on standardized hashpower, Grayscale estimated total Zcash mining activity has increased by more than 2.5 times this year, adding the trend could create a virtuous cycle.
