wow 0.15 BTC/month?? woow
i read it was 1BTC per 3 months... this 0.15 makes 1 BTC every 6 and a half months.
I'm evaluating to start a Mining Biz here in Chile but according to the new difficulty factor you can get 0.15 BTC per month.
With that and the high cost of electricity here 0.18kW i was estimating arround usd$300 in electricity per unit (Antminer S9) per month... and with 0.15 BTC a month you get arround usd$350...if everyting works perfect......
something wrong in your math, if an antminer s9 consume 1.4 kw/h for 24 and for 30 days, running this thing, you will end with 1000 kw/h per month
1000 kw/h at 0.18 cent each, is only $180, the miner make $400, so you have $200 net of profit, which is 6-7 months for roi
