Would it really be profitable to use the rockminer's T1? Consuming 1000 watts per unit, and add on that you need your own PSU, lets say with about $0.095 per kwh, It would consume $0.095 per hour, right? And makes about $0.21 (current market value) USD if turned from BTC.... I can make a $0.115 profit from using the miner. to find out days, let's multiply these factors by 24 (to find out 24 hours in a day)
$0.21*24 = $5.04 produced
$0.095*24 = $2.28 cost for power
and the total profit (produced - cost for power)
$0.115*24 = $2.765
Now the price of a rocketminer (going to use zoomhash for this if you would like to check) is about $350, plus a power supply unit, (
http://www.newegg.com/Product/Product.aspx?Item=N82E16817182188) would be $130, plus or minus $15 depending on the unit. So,
350 + 130 = $480.
To figure out how many hours you'd have to mine let's divide the hourly profit from the total price of hardware.
$480 / $0.115 = 4173.91304 hours.
So, 4173.913 hours to make an ROI at current market price. to find days,
4173.913/24 = 173.913042 days, or 174 days to make your Return of investment (how much you paid to begin with)
... Is this even viable.. making $2.765 dollars a day per miner...?
Then the question arises.. If it's so profitable to mine, why don't companies that make the ASICS use it themselves?
Anyone willing to answer, share thoughts or comments is truly welcome because I was looking into purchasing 3 Rockminer T1's.. But after the math...
Also - what about heat? How much heat is produced per unit? Even with fans, heat has to go somewhere.. That somewhere being the room the miners are in. So about how much is produced if anyone has had or has one I'd appreciate it.
*NOTE: THIS IS NOT IN ANYWAY 100% ACCURATE, PRICE OF BTC CHANGES CONSTANTLY AND IS SOMETIMES NOT PREDICTABLE.
**NOTE: I used Coinwarz.com to find out this information at an OVERCLOCKED miner which has a hash of 900gh/s MAX.. but the hourly mined would be $0.19, and the profit would be about $0.95 (US AVERAGE FOR SOUTHEAST RESIDENCE) if you had it at the stable clock of 800gh/s.
***NOTE: Price of powering the units may change according to your location.
I have 10 of these units, so:
10,000 watts @ $0.10 kWh leaves you with roughly 0.06 to 0.08 BTC per day after paying electricity (real world earnings not based on statistics). Regarding heat you can calculate the BTU's off the watts. Personally I use an insulated two car garage with industrial window fans pulling some 10,000 CFM of air in/out.
That's ~2.2 BTC a month profit if the difficulty never changes. When mining Bitcoins you should expect roughly a 25% return on you initial investment. I guess the question should be, is ~25% "so profitable"? I'm cool with it.
