I am a bit confused with the word rig and workers. On the explanation, it was using rig and workers but after reading the example provided, I am still a little confuse.
I am mining on Conflux (Herominers, T-rex) with 1 rig consist of 2 GPUs. I understood that this setup should be Free.
If I am planning to increase the current 1 rig with a total of 6 GPUs, how much will I be charged? It is at a total of USD$3 per month because there is only 1 rig?
