Whay Bitamine turnoff their S3 at Hashnest ?
Jan 14th, 2014 - Umisoo, ANTS2, ANTS3 Hardware Powered Off
Today, at 08:05 Jan 14th GMT, all Hashnest Umisoo, ANTS2, & ANTS3 units were powered off, as their maintenance fee became higher than their payout. This procedure was previously outlined in this post
https://forum.bitmain.com/bbs/topics/969.
At the moment, we are examining the situation to determine what further action will be taken. We will be doing our best to keep you updated with the latest information. As long as the machines are switched off, there will be no new revenue payments from these machines. Further, we will collect no maintenance fee on the Umisoo, ANTS2, and ANTS3 during this time.
Note: GH/s trading for these units will continue as normal. Users may still buy or sell mining contracts for the Umisoo, ANTS2,
and ANTS3 during this time.

Because maintenance was higher then payout.
Why S1 are
selling at a price of garbage ? Because maintenance was much higher then payout.
And within 1-2 month S3 waiting for the same thing.
Even with free electricity there is no way to ROI at 0.65BTC.
If BTC prize will rise then diff will rise too and maintenance will cross 100%.
If BTC prize will go down maintenance will go up and cross 100%.
Things are worth as much as someone wants to pay for it.
