Would it really be profitable to use the rockminer's T1?
. . . . . . . . .
***NOTE: Price of powering the units may change according to your location.
Good analysis and calculations. The ROI, however, changes when difficulty changes. Every 14 days (maybe less if difficulty increases).
If it's so profitable to mine, why don't companies that make the ASICS use it themselves?
They do. AM started off self mining in 2013. Rockminer also has a small farm as well.
If a company can sell a miner for S dollars/euro/bitcoin or they can make M dollars/euro/bitcoin for self mining.
Whichever is great M or S is what they do. Since companies are selling miners, the company believes that S>M in this case.
Thank you, I did what I could with what I had. I just did some quick mathematics to find out what it would be worth/like. But the case is, the Rockminer T1's give the highest Mh/s per USD than any other miner out there. But it's in great part due to its high-needed power requirements.
More math time.
For the total investment was stated earlier of $480, you can purchase 1. Right? So lets say we get 3 of these puppies and haul ~2.7Th/s (or 2,700Gh/s) Overclocked, at a price of about $1450. (Add shipping depending on your needs)
Now, we need to figure out how much ~2.7Th/s (using the ~ (about) sign because variables play a lot, so I'll use the max safe overclock)
With an hourly rate of $0.63. For daily mined it would be:
$0.63*24 = $+15.12
Now the power consumption also triples, because instead of 1000w, we'll need 3000w, and using the same rate of $0.095 per hour per unit. So:
$0.095 * 3 = $0.285 per HOUR that the miners run.
And to figure out the daily,
$0.285 * 24 = $-6.84 per day.
So adding them up, daily you'll get a profit of :
15.12-6.84 = +$8.28 daily.
As for paying off and getting your ROI, it would be about the same as if you had one because your total invested went up, but so did your mining power and they did so proportionally. but lets do the math for it using the profit.
$1450/$8.28 = 175.12 So about the same days, or a little over 6 months. Now the same notes apply as my first math post. But the questions arises.. Is it worth it?
as Chris_Sabian stated, the companies sell them or use them depending on the outlook of profits.. So, as he said if profits for Selling > Self-Mining, how is that supposed to make us costumers feel better about going about and purchasing such products if these companies felt it didn't provide as big a profit..
