So for one month of hosting you are asking for 140.00
If we do the maths, one s9 runs around 2k. Add the power supply and its 2100 approx.
If you charge 140.00 that equates to .15kwh. At that point the math looks like this
http://www.mycryptobuddy.com/BitcoinMiningCalculator/path?hashrate=13.5&powerCost=0.15&power=1300&hardwareCost=2100&sellingProfile=expensesWe are assuming at 8% difficulty increase(as par for the course over the last 10 years) and a 1% pool fee, as well as selling coins necessary for paying electricity.
So per month at the current pricing(not taking into account bitcoin may go down to 3k)
So based on these numbers the hosting company would be making 140.00 per miner per month, and the miner would be making 68.00.
Also we are needing to take into account while the hosting company would be putting out an initial investment of time and money to get the space up and running, you would also have the appreciation of business to resell the company for profit or if there is another spike new equipment could be installed.
So the numbers look like this. 1 year mining s9 at .15 cents turns a profit of
negative 1950.
So if you would tell me why anyone would use the service at this price? I would appreciate not speculating on the future cost of the coins, because we are mining for the present. If we were to speculate on the future costs, then we could also assume just investing money into the coin for a speculative future gain. And if thats considered it trumps mining
