Okay there are 4 or five miners worth mining ltc/doge with

bitmain

l3+ =            480-550mh     800-900 watts

l7  =                 9500mh         3200-3400 watts


innosilicon A6+  2200mh.       2100-2150 watts


goldshell

L5 pro              2455mh.     3000-3100 watts

L5                    2050mh     2080-2150 watts  

if you take a good look

bitmain l7 is 19x the hash and 4x the power of the L3

So if you have 2000gh you have 210 l7 as 210 x 9500 = 1995 gh and burns  714kwatts.

you are also making very serious cash.

as 1995 x 0.022499 = 44 ltc a day.  10000 usd

and 44 x 2000 = 88000 doge a day 26400 usd

714 kwatts per hour = 17136 kwatts a day.  make it 18000 kwatts a day that is a 18 megawatt complex. or big real big.

so 36000 usd a day earned and at 5 cent power only 900 in power

net of 35000 usd a day.

if you got your l7 gear at 10000 each you are paying 3.5 off a day.

so make it 11700 each you pay off 3 l7's in a day so your 210/3 = 70 day payoff.

Must be nice for that farm.  Which if it is in one place is huge.
