Thank you for this.
Im starting a GPU mining farm, just because i got really cheap power. I have nearly 50kw available for only 0.037 cents a kw/h.
First 10kw are in with 70x RX5700 gpus
Cheap power is the secret. You have very good rate to be here for long time.
I would mix it up with some aisic miners just to diversify. But your gpus seems one of the best for roi currently.
