The difficulty would need to double before I would have to start down clocking my miners at the present price. I want to scale up, though it is a strategic choice however, everything considered deciding to skip a generation of miners does not mean I have stopped scaling up. It does not always make sense to buy every new miner on the market. Much of the challenge of being a profitable miner is knowing when to buy equipment and when not to buy equipment. For a long time Antminer did not have any competition for their latest miner, this is why I suspect they are charging much more then it actually costs for them to make the unit, I was hoping that the increased price would bring about more competition in asic manufacturing and therefore bring about more favorable products. Saving my Bitcoins to buy into the next generation, still thinking it is a smart move, if price skyrockets then it was the wrong move but that can always be the case in retrospect, everything considered I think that I am doing the right thing. My mining operation is thriving and I expect it to continue to thrive, as long as Bitcoin does as well.
