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.
