My power consumption is becoming insane ( nearing 3kwh ) so I'll gladly do the math for me to see if it's beneficial.
For me 1kw electricity 24/7 31days is 178euro.
My 4* 280x rig uses ~1.110kwh and delivers 2.88MH ( including setup )
41* Dual miners would use ~ 103kwh and devilers 2.87MH (excl setup , anker usb hub + fan uses ~3.5w )
So my electricity cost just went from ~200e to ~19e , let's say I am saving 180e a month
Cost :
full 280x setup ~1600e
full dual miner setup : ~4000euro excl shipping+taxes
so a ROI of over a year.
You should be able to build cheaper high hashing rate LTC only miner with DualMiner USB. Please remember, DualMiner USB are priced with volume discount;
* Price (per unit)
1~9 $98 ea. Full Price (FP)
10~49 $92.12 ea. 94%FP
50~99 $88.20 ea. 90%FP
100~299 $83.30 ea. 85%FP
>=300 $79.38 ea. 81%FP
Try your best to take the advantage of our volume discount program. Our Chinese partner uses lots of Orico P10-U2 USB2.0 hub, which you could get it for low $20s/unit, for its production testing purposes. Each Orico P10-U2 could host 10 DualMiner USB devices for mining. So, you could build your own 4.2Mh/s miner with 60 DualMiner USB devices + 6 P10-U2 hubs with the cost of $4762.8 (60x79.38, assuming you could get the unit price $79.38 for each DualMiner USB) + $175($25x7) = $4937.8.
imho it's too expensive but the advantage is power saving n less hassle & noise !
i paid approx usd 5000 to get 7 r9 290's 2 axi corsair psu 1 mobo , ram, cpu & i'm hashing away @ 6mhs+ (i have mobo n extra psu @ home)
well just my opinion.
computer parts can sell ! usb sticks hmmm well u tell me & it's too light to be paperweight
these sticks only make sense to some one that will sell some on ebay. and keep some to mine.
The price is too high. especially for a winter roll out.
I am in New Jersey I am burning 1600 watts for mining and what do I get for 1600 watts 4 pc's pushing 2600kh for lite coin and 100 usb sticks pushing 210 gh for btc. All my gear is paid for /roi'd.
so If I want to sell some of the usb sticks and swap this in does It makes some sense? Not really.
If I want to kill off a gpu and put some of these sticks in does it pay to do so? yes , but since I am getting free heat I will wait until April or May.
I know there are miners that would want these more then I do as they live in warmer areas or have really high power costs.
My 4 gpu pcs. burn 1140 watts to get the 2600kh for lite coin. I burn 460 watts to get the 210 gh for btc.
The lite coin is clearing more then 400usd a month,but I think I will buy a few of these just to say I have some.
If I compare one of these at 92 usd vs 1 ant miner at 46 usd. what is the better value?
I can get an antminer for 46 usd sent to my home in 3 days. Then mine it for 10 days and sell it on ebay for 59 dollars or
better yet 3 x antminers = 138 usd. Use them to mine for 10 days and sell on ebay as a set of 3 for 177 usd.
If I do this 20 or 30 times and eventually I have a lot of no cost antminers.
I am not sure I can do the same idea with these sticks ,but I will give it a shot . I think I will wait until after Chinese new years ends.
BTW
Just a suggestion 01-09 = 98.00
10 -49 = 92.12
50-99 = 88.20
this pricing setup may work better for you.
a level of 1-9 = 98.00
a level of 10-24 = 92.75
a level at 25-49 = 89.10
a level at 50 -100 = 87.70
many resellers can't push to 50 x 88.20 = 4410 usd
but they can do 25 x 89.10 = 2227.50 usd
you would be more likely to get a decent amount of orders from a seller that wants to run 10 and sell 15 on ebay.
