I get exactly what you're saying. It seems that existing hashing did not get capped for a year, which I'm grateful for. However IMO after maintenance fees @ 240/yr for 1TH with expected difficulty increases; not even worth it. 120 even for a year will still net you more. Other hash rates are just crazy prices.
I find it funny this increase happened right after bitmain had put miners up for sale less then a day prior and sold out.
I'm not upset with the performance I'm getting from them, but I will not buy any additional hashing power at double what it was. Especially when BTC is MUCH higher now.
