okay simple math I buy 5 s-3's cost = 3.3 btc or 1930 usd I buy 2 evga 1300 psu cost = 340 usd
I am at 2270 usd for 5 x 440 = 2200 gh I burn 5 x 340 watts = 1700 watts
So 2270 usd 2200 gh 1700 watts = s-3
or 2399 usd 2000 gh 2000 watts = you
the power difference of 300 watts is about 21 usd a month if your power is 10 cents a k-watt.
So lets make your gear perfect. Lets make you honest. Lets make it ship fast and not broken.
you need to lower the price to compete with bitmaintech.
Your gear should be 1899 to 1999. That makes it priced about the exact same as bitmains s-3 once you figure the power in.
