bump it up cmon boys give me real offers.
Hard to go above 2 BTC when 1.8 BTC will buy 400 GH of Antminers that use 800W. Your unit uses 2100W yet is only 20% faster.
If you put in a mining calculator two antminers after 90 days after power you make $1022
If you put in the BFL 500 after 90 days you get $1044. Power cost is taking almost all of the extra speed advantage.
At the 90 day point the ANTminers are more profitable due to the lower power usage. This is at 10 cents a KWh. If your in NYC or CA, forget about it. If you are in a lower power place you might do OK with the BFL 500.
