Coins per 24h at these conditions 1.7460 BTC
Revenue per day more than 1700 $ (MtGox-price)
i dont believe that pyramining has electricy costs of 1700 $ /day
On the face, true, from a post by pyramining current gen asic runs 2.5w/1.6gh. I can't find a cost for pyramining kwh, but at .15c its about 30usd/day to run the asics, however he is likely still running the fpgas which are magnitudes less efficient.
When he brought on the current gen of asics they were earning us 35btc/day now its 1.7btc. We have also discussed to death the way the mining hardware/income is split between deposits.
EDIT: Another thought...
Its entirely possible that he hasn't split the entire 4.8ths with deposits. Only 2.2ths or so was actually queued up before installation. Its plausible to me that he has some if not all of that remaining hardware mining for reinvestment purposes, Minus of course the deposits that have come in since then.
