That's my thoughts too, but that makes it $49/month for a TH which I find too cheap. for a 0.7W/GH that would mean 700W for a TH and a power cost of just 0.03$/kWh. It's either that cheap or something is fishy here. And if AM can get so cheap power why didn't they self mined faster or stronger? That power cost is a miner's wet dream.
Can you clarify how you get to $0.03/kWh?
I get the following:
For 0.7 kWh for a TH and 0.1$/kWh, we get (about) 0.7*24*30*0.1 = $50.4 per month in electricty costs.
So these maintenance fees indicate that AM gets electricity for less than $0.1/kWh. It does not indicate they get electricity for less than $0.03/kWh.
That's much more reasonable (and not even particularly cheap if they indeed pay $0.1/kWh, but I would assume they pay somewhat less).
). To cover
the cost of electricity with $1.6 per day per TH/s, they have to get it for less then $0.06/kWh. But I guess that maintenance cost also includes renting space, colling, support,... ?
