I'm at 1.5 THs and about 1 1/2 months ago, I was earning well over 0.1 everyday (Slush at 1800 THs). For granted, some days I wasn't making that much. Currently, with nearly 4000 THs, my earning has been cut by half. With today price ($610), I making about $30 a day. It's getting worse every day for avg. miner.
You could either keep up the hashing race or you could trade (other alt coins).
Actually, it's getting this much harder even for the industrial sized mining operations. Primary difference is, they have higher profit margins as a result of lower electricity costs (in most cases). Coupled with selling off the hardware as it approaches uselessness and a significant portion of mined BTC being directly reinvested into additional, more efficient hash. But even the larger operations are suffering. Bitcoin price is going to have to rise drastically here over the coming months or a whole lotta people are going to have a bunch of useless heat-generators sitting on their shelves at home. I know I do. My BFL gear (65nm) stuff is about to get shutdown and I'm only paying 0.07/kw/hYou could either keep up the hashing race or you could trade (other alt coins).
I had free electricity up to 20KW/h (heat limit) and I still stopped my BFL gear last month. I was making more per watt with my scrypt miners than I was with the BFL gear. Sadly it will be going to ewaste recycling shortly.
got it?
