tip: doesn't Bitmain usually advertise them self , when they do world wide sales ? .... or they have in the past even for used junk . just saying  nothing more I'm sure bitmain is selling these 5k plus units  but id hold off ...


an what ever happen to the faster they got the Less Electricity they used by that I mean miners doing lets says 15 th using below 1 k watts or 900 watts ...... or 15 th with 900 watts @ the wall .... well anyway i knew that was a pipe dream, right now.  they do indeed use less now but I expected better power usage by now . but then again they also don't make home miners either like they did once upon a time or when they first started  out . just my 2 cents worth .
