Thanks for the article. I was hoping it would at least compare regular mining to cloud mining to assist with making an informed unbiased decision, but instead it was just a math formula comparing apples to nothing.

Your statement "The wisest choice would be not to cloud mine at all," eludes that the positive horizontal asymptote is something unique to cloud mining. Can you demonstrate how regular mining compares? With rising cost of power, or even with just the cost of power, regular mining you actually start to lose money at some point, which isn't something that happens with all cloud mining contracts, not including the initial cost of the mining contract or the cost of the ASIC for simplicity sake.

I am neither pro nor con cloud mining, excluding centralisation concerns. I am currently doing both as an experiment, and appreciate the work you have done, and wouldn't mine adding what you did to my research as I think it adds value, but the conclusion just doesn't make sense without comparing it to something, or at least the statement I mentioned doesn't make sense. Once you compared the two, your conclusion would need to be (based on your view above) that the wisest choice would not to mine at all. Bitcoin uses PoW and mining is essential regardless of how it is done.
