They are trying to sell their Giant+ at $4000 at the moment. Considering that all their other miners were sold out instantly and they are now actively emailing people trying to sell the Giant+ I think it's safe to say that the Giant+ hasn't sold as much as they expected.
If they really have another miner almost ready I would expect a price drop for the Giant+ very soon, so we'll see...
their 2 Gh/s miner was sold in China only, and to "friends" or busines partners there, while being kept a secret.
They played the game and they overplayed their hand. Now They're paying the price for it. One of those things isnt worth much over $1000, maybe $1200, at todays and especially October's hash rates.
Kept the miner from the public eye for too long, no one knew about it, and only a few select guys in China had units.
Then they saw the Ibelinks starting to ship out, the difficulty increasing, and they tried to dump their 2gh/s miners for $7000 a piece....a price based on the April 2017 hash rates. Cue Innosilicon announcement, cue Bitmain announcement, and their 2gh/s machines are all of a sudden not worth much more than the price of manufacturing.
Also agreed, once Bitmain comes in, its game over for the little guys.
