Most of the calculators show that if I ran 10 S9's (or the equivalent) I'd be able to make a significant amount of money.
These calculators show I'd be in the green:
This one shows I'd be in the red:
All of the calculations have been using my current electric rate of $0.08/kWh and based off of an Antminer S9 (14TH and 1325W power consumption).
In case you care, here is my plan. After setting up this "farm" and running it for a few months I'd want to save enough money to replenish the machines as needed or to buy upgraded versions (like the rumored S11 or maybe the dragon) and keep this farm going long-term.
Another question - does anyone have access to a good and historically reliable difficulty estimator that I can try to estimate long term gains/losses (I know it would be hard based on the volatility of BTC and difficulty changes but I'd be silly if I didn't try).
Final Question- Does anyone have access to historical data representing daily or monthly returns to date using S9's or other hardware? I can't seem to find a chart online anywhere and it may be useful to determine the rate that which profits decline over time.
Final Final Question - I'm exploring the idea of starting a company/LLC for tax purposes and maybe a lower electricity rate. Is this a good/bad idea for this small kind of setup? Would the potential tax advantages be worth it? I would be running this out of my home in the western United States.
I know this is long so thanks for bearing with me.
