"Our power price of $30/MWh gives us a meaningful cost advantage that could be important relative to many other miners post-halving. For our proprietary mining at Project Dorothy 1B, our average power efficiency is 28 J/TH (across our fleet it's approximately 25.7 J/TH)," said CEO John Belizaire, in the monthly AMA for April.

"Project Dorothy 1A and Project Sophie have similar efficiency levels. Our hosting customers are some of the industry's leading miners. We're implementing a number of optimization strategies at each site to ensure maximum profit."
