At efficiencies like Valery is touting for his new 16nm process chips, things are going to be turmoil for quite some time on the mining front. Of course, they may never appear, but we can't really say BitFury hasn't got the technical capabilities to produce this kind of tech, in volume. If you think diffs are bad now... well, we ain't seen nothing yet it seems.
I bought three Avalon 6's not too long ago, and after having trouble keeping them cool enough to run at full speed, sold them off... and looking at the landscape now, it looks like the 'wait and see' game might be the best thing going right now, unless you are a whiz at turning equipment around quickly.
I swear if there was any PoS coin that didn't lose value as fast or faster than it spit out coins, I'd be doing that right now and waiting to see how the ASIC landscape plays out in the next few months.
My guesses are that the halving will be a huge boost in BTC value making all of you guys mining right now for those .01 payouts everyday very happy you kept at it.
