What is the maximum monthly generation of bitcoins with a Mining Operation using a series of Antiminer S9 worth of $100,000 today, the 13th of Decemebr 2017?
OK, so the next batch of S9s mines at 13.5 TH/s and costs $1415 – with PSUs at $105 let’s say each one costs $1520. So for $100k, you could buy 65 of them. That would give you 877.5 TH/s. At the current difficulty, this would mine 4.16 BTC per month. At the current price ($17,300), that would be worth $71,968. Of course, power and other operating costs will a large portion of that.
