Have you tried asking anyone in washington?
So all miners are from Washington now? Or all AM customers are from there? What about the rest of the miners?
I wouldn't recommend mining to anyone that pays more than $0.05/kwh.
It doesn't matter what variables I use because however you look at it, it beats everything else available.
Instead of arguing whether this will ROI or not (which is entirely pointless speculation) how about showing us a miner that has a better chance?
Well following your statement nobody should buy AM Prismas if they have an electricity cost of over 0.05/kWh so why bother showing you different miners?
How do you figure the SP35s are cheaper? The price on 10 Prismas is 14.9BTC or 5960. To that you need to add 5*($45+$60+$3.50*8 + $10) for a DPS-2000BB/breakout/cables/shipping = $665
That's $6625 for 10 Prismas, which unless the SP35's have had a large price drop recently is still cheaper than two of those.
I used the numbers AM shareholder Mabsark posted here:
SP35 costs 4,035 USD inc. PSU + shipping for 6 Th/s at 3.5kW, it would take 147 days to break even,
10 x AM Prisma costs 9,250 USD inc. PSUs + shipping for 14 Th/s at 10.5 kW, it would take 158 days to break even, and
S3+ B9 costs 320 USD inc. PSU + shipping for 453 Gh/s at 355W, it would take 173 days to break even.
