You will never get your bitcoin back if you buy one of these at this price. It isn't even close. This is for suckers or those with stolen electricity.
I would say the PACMiC and S5+ was the sucker's call. This thing is like the HA-HA afterward. I mean they, Bitmain, knew they had that S7 right around the corner. Yet they throw up the S5+ at a ~$2300 premium and at .444 j/GH. Then boom what not but a week or two later drop the S7? Dirty pool.
