Your license allows you to generate unlimited builds and run them on unlimited computers. There are no restrictions about this so feel free to create all the test builds that you deem necessary to gain confidence about the miner before spreading it.
This miner supports proxies that you can add while creating your build. Using proxies allows you to point multiple builds to the same mining pool, increasing the income obtained from a single worker.
Rogue Miner will always use system CPU at your chosen %, unless you're running the miner on a system that has low specs. If that's the case the miner will use all available power to be able to produce an income.
