50 T/H worth of mining power will get you about 3 bitcoins per month in January 2015. Think about that. We're talking at least tens of T/H early next year and hundreds of T/H later on in 2015. This should not be too much of a surprise since just last year a 5 G/H Jalapeno was actually worth something in the beginning of 2013.
By the way, a 5.4 T/H miner delivered in August will only get you back about 6 btcs.
...and 50T/H will need about 50KW of electric power ...at current efficiency of 1W/1GH...and will cost you ...@$0.10/KWh * 720 * 50 = #3600 ...

BTC @ $1200 is about breakeven ...Overhead...hosting etc...is extra...

Hard to believe that mining will be the same by the end of 2014...
