Problem with hosted mining, which is basically what you want to try and offer, is simply that of transparency. Will you be able to share details such as:
1. Accounting for overhead and maintenance? Bills and the like?
2. Proof of revenue? Blocks found, etc.
3. Proof of operations? Video and Pics of the rigs etc.
I've no doubt Iran is a great place for mining now, but what happens when power spikes are noticed by the govt? Surely repercussions... 90 cents for 1 kwH a month, what does that mean? 24/7? How many units are actually being consumed? What's the actual cost per kwh? What's your bill say? All these questions you gotta be able to answer
