Fun with numbers:

1 GHs today = $0.1591 per day ( https://www.byteminr.com/stats )

CryptX at 0.017 today if hashing = $13.60 per GH/s, break even in about 85 days with no difficulty increase.

CEX.io at 0.041 today = $32.80 per GH/s (plus fees?), break even in 204.85 days with no difficulty increase.

Butterfly hosted hashing two months minimum from now (i.e. March 2014) = $10.83 per GH/s, would break even in 68 days if starting today and assuming no difficulty increase.

Byteminr.com about 1.5 months ago before running out of stock: $20 per GH/s/Y, break even etc. etc. in 125 days.

Bitcoin total network speed: about 18,000 THash/s, or the equivalent of 9,000 Cointerras. I wonder how many boxes the next gen miner manufacturers can produce in a month, combined? The equivalent of 36,000 Cointerras entering the network in two weeks would trigger the protocol's protection for sudden difficult increases, limiting it to a factor of 4X every two weeks.

In fact, if somebody could manage to inject insane hashrate into the network today, they could just eat the blocks away for several months and benefit from the 4X difficulty increase protection in the protocol; the network would produce blocks faster than once per 10 minutes for a while.
