The monthly net profit would be somewhere between $3500-4250/month based on 12.5 TH/s average per S9 and 504 MH/s per L3+. Thats assuming BTC exchange rates continues to fluctuate around $7k/BTC and network hash rate stays the same.

How do you figure? Just trying to work out your math.

Your numbers/assumptions:
* 105 12.5TH S9s gets you .00048BTC per day per unit = $10584, assuming $7k/BTC (105 x .00048 x 7500 x 30)
* 2 10.5TH T9s gets you .0004BTC per day per unit = $168, assuming $7k/BTC (105 x .0004 x 7500 x 30)
* 12 504Mh L3+s gets you .00025BTC per day per unit = $675, assuming $7k/BTC (105 x .00025 x 7500 x 30)

That gives you a total current revenue stream of $11427/mo.

In the initial post and the electric bill posted, the current cost is $12206/mo (11206 + 1000 rent).

Where are you getting $3500-4250 in profit/month?

FWIW, that's not at all the projections I used when I modeled this. I looked at 50 14TH S9s and 55 11.5TH S9s, looked at logarithmic growth of network difficulty - which matches the historical growth, and I used multiple pricing models to calculate the cost of BTC over time. That being said, its *still* moot because we don't know the actual models and number of each - which make a HUGE difference when calculating revs.
