I just saw i could rent about 125ghs for around $54 for 4 months not a bad lotto ticket.
You could buy a used S1 for about that and have 200ghs for as long as you want. I'll sell you one + psu if interested.
The power cost is missing if he rents power is 0. If he mines power is ?
Power cost is the main reason for renting my electricity rate is .13 in nj
I'm double that in California, but I enjoy the hardware aspect of mining, too. (obviously I don't mine for profit)
