The office buildings we are in have pooled utility expense, so our increase in cost is barely perceptible.
Welp, there's the sleaziness every bitcoin operation has to have. Most miners have 50-75% of their revenue eaten up by their power bills, but you've managed to negate this problem by spreading the cost to others without their consent. I'm sure the other businesses in your building(s) would love to know you're running a dozen computers at full power drain 24 hours a day.
Have you projected how long it will take you to get solvent? (remember, revenue =/= profit, common bitcoin mistake) How will you handle the price of bitcoins going down, and the difficulty going up?
How is it sleazy at all? I have a 5 year lease agreement that very clearly lays out what is allowed. We are absolutely in compliance with that agreement.
I love how people just assume to know everything.
We are already solvent, so I am not sure what your question is. Are you asking how long it will take us to pay off our capital investment?
Like we have said a few times already, the price of BTC/USD is not a primary focus for us. We seek to mine BTC, take investment in BTC, and pay dividends in BTC. The obsession with the exchange rate by some people is completely missing the point of what we are trying to accomplish here.
Finally, last time I checked the difficulty has dropped 3 or 4 times in a row. It is our belief that we have hit a ceiling in terms of difficulty increases.
