however, we want to do another host model in this farm, eg cloud mining mode.
we want to sell hash rate directly, the price should be 369$ each Th/s @ 0.3watt/gh/s , so the daily host fee will be 0.3*24*0.07=0.504$ for each Th/s, we will calculate the mining earning according to 4%pps and pay the earning to customer each day after deduce daily host fee(we will transfer daily host fee to bitcoin according to exchange ratio from bitfinex at 9:00AM(UMT+8)each day).
that is a similar model like hashnest, the only difference is that our host fee is better, and i also will not charge for expensive off-shelf fee when the project is end. i will try to sell the miner on used miner market and pay the money directly to customer.
Great idea!
