I actually have 2 running but I'm cautious to run the majority of the rest of mine primarily because it is the beginning of spring time here and I haven't found a viable solution to combat the massive pollen in the air right now. I understand that I'll obviously still make money if I continue to mine daily if BTC goes back up, its just I'd rather see where things go with the market before I put some time on the newer miners that I have.
How high is your electric rate? I'm at 9.6 cents/kw and I'm still making money. Can you not put in some Merv 3 filters to deal with the pollen without adding too much backpressure?
Doing the math here, I think I'll even be ok during summer pricing, which goes just over 12 cents/kWh.
Although, I have been wondering about the peak pricing option. Not worrying about it now, because I don't have enough machines yet, but if I had considerably more would it be beneficial to switch to the peak pricing and then shut down for five hours M - F. That's 25 hours of downtime out of 168 hours, skips 30+ cents/kWh and runs during off-peak for lower 7 cents/kWh.
If I ran straight through, the average would be about 12.05 cents/kWh. Less than the normal pricing by about .5 cents.
