I explain my case, a friend offered me 2 D3 for 700 dollars with power sources included.
But I do not know almost about ASICs. I do not know how to refrigerate them.
But I would like to know how much it produces, I have 0 dollars of electric expenses.
Should I buy them?
dude dont listen to these guys... buy those 2 off from him for 500usd and then you will make 4,50usd per day per asic... so ROI 57 days... (based on that you dont pay electricity)
given your situation I would do it...
