Sorry I made a newb mistake (AT&T made the same mistake on MB usage on phone contracts if I remember correctly, although that doesn't excuse my brain fart.)

1.7 cents per KWH - this is the number I wanted. I also feel its accurate because LabRatMining is also getting the same leccy rate (yes leccy is the sparky zappy stuff) - https://bitcointalk.org/index.php?topic=251423.msg4699831#msg4699831

So with a full custom 28nm chip they are going to be one of the most, if not _the_ most, efficient chip on the market. And with such cheap leccy..... even if a number of competitors all:

1. manufacture their own full custom 28nm chips
2. sell their own chips as per 1
3. mine with their own chips as per 1
4. can also secure 1.7c/kwh leccy

ActM will still be equally profitable and therefore, unless people start mining at a loss (um no), will be profitable indefinitely.

It will take a number of manufacturer/retailer/miners with a chip much smaller than 28nm (20nm isn't a big enough difference) and leccy at-least half the price (not gonna happen) in order to make ActM unprofitable... this is a LONG LONG LONG way off, and would give ActM plenty of time to produce a more competitive chip and find cheaper leccy (although I doubt that's really going to happen)

Vince out.
