How much are you earning a day and on what cards?
I am using RX 470 graphics cards. 6 in numbers with Nicehash enabled. Earning $250 to $300 per month with these six cards. The electricity expense in average comes aruond $15. Worth and standard income. Increasing capital would certainly bring more income. Planning to invest more and expand.
Jesus christ that is some low electricity cost!!!! If i had that low of a cost i would turn my entire apartment to a mininghouse. You could even use ACs to cool down your rigs without even moving your yearly electricity expenses
, would literally buy any available GPU there is
