We had 19 THash at the begin of the year. Now we have 2200 THash (so 19 THash is old HW and 2180 is new one .. asics)
Edit: and at the end of year we will have 10,000 - 20,000 THash ... new 28 nm asics
yeah , but those are running at 6-10W/GH , which is 10 times more at best.
Well it still leaves room against the current electric bill but I doubt that will see any mining equipment bought before August still running in January.
My point was that miners who haven't changed their equipment are having a hard time right now.
