If you:
A) own a spare atx psu that will run 2 s-3's
B) already are paying for the internet
C) have a few cat 5 cables and a spare gigbyte switch.
you need only buy a pair of s-3's and pay for power .
2 s-3's are .128btc
if diff = 11% over the next 6 months they do btc roi
So where do you get 2 S-3's for .128 BTC (i.e less than $100)?
That sounds like the steal of the century, or is the price wrong?
Two go for 1.17btc with coupons....
that was a missed decimal point. and 2 miners for 1.28 was a good deal for me. they have earned more then .4 btc back against that price.
you need to look at it from watts per gh.
300 for 1gh was a money making gpu in april 2013
10 for 1 gh was a money making AM cube in July of 2013
2 for 1 gh was a money making bitfury chip and still can make money
many pieces of gear were 2watt gear.
1 for 1 gh was and still is money making gear
.75 for 1gh is the current common money maker the s-3
.64 for 1gh is the sp30
the improvements in watts are ending so diff slows.
june 2013 to dec 2013 = 25%
DEC 2013 to july 2014 = 18%
July 2014 to Jan 2015 = ? my guess is 12% at worse 15%
