no way that they will be giving out $100 coupons if profitability was good.

They are turning inventory and volume sales.  Bitmain is also clearing out the inventory that has already produced a profit for them.

Looking from our perspective: ROI in 2.5 months and 1 month profitability plus the sale of the S7 in future months.  

I don't necessarily disagree, but difficulty could go up 60% in one mo if 14-16nm machines will go on sale or THEY start mining with them.
What would be the price of such resale be in 2.5 mo, $200?
Money better spent just buying (or not buying) btc here, IMO.

You kinda hit one thing on the head this is killing resale value of S7's.  And the interesting thing is it likely will effect all other miner's prices to.... which becomes interesting. 

So really good for someone buying a bunch of new S7's (assuming difficulty does not shot up insane).  But difficulty has become hard to predict.  They will sell though inventory though I predict at this price with coupons.  I did not see this coming personally.

I ordered one S7 Batch 15, but the order shows Expired even though I paid it on time.
Shows Paid, and the Paid and Confirmed value are the same.
Opened a support ticket, but I still have one open from 2015, so I am assuming I need to do something else to get their help ?

email to info@, but typically this would be squared by tomorrow am US time, but since it is a weekend, by Monday am Beijing time.
They are 12 hr ahead vs the east coast, so if nothing happens by midnight tomorrow, i would email.

Looks like they fixed the order, didn't respond to ticket but it now shows properly paid.

That's awesome how they got 18 pool configs into there.

you mean like this ?
with API calls, bitmain leave full access from from any address

Looks nice. Which software is this?

[Subw]

that's work in progress (paused for now)

I am having an issue with 3 of my s7 batch 2. They are running but not mining and I am not sure what do there seems to be no CG Miner after my last reset.

That hardware version reporting as X.X.X.X with no hashing was discussed a page or two ago in this thread.  The person who reported it was able to fix it by reflashing the firmware.  I mentioned also that I had seen this behavior on previous antminer models (but not my S7's) and was able to fix it by doing the reset to default button.

Make sure you are careful when messing with firmware.  If you have anyway to have a battery back up or way to make sure it does not lose power, and also make sure not to close window till finished.

I hate doing firmware updates myself.  My miners normally stay on the firmware they were shipped with at this point.  Changing firmware is kinda the last fix I try.

I have (10) S7 coupons if anyone is interested in them.

ROI looks pretty good and with the $100 coupon and quick shipping even better.    

no way that they will be giving out $100 coupons if profitability was good.

They are turning inventory and volume sales.  Bitmain is also clearing out the inventory that has already produced a profit for them. In turn, they are incentivising their product to move it out the door quicker.  Check out their business model:  1) Their own mining operation 2) Their own pool and 3) product for sale.  All three working in concert.

Looking from our perspective: ROI in 2.5 months and 1 month profitability plus the sale of the S7 in future months.  

I don't necessarily disagree, but difficulty could go up 60% in one mo if 14-16nm machines will go on sale or THEY start mining with them.
What would be the price of such resale be in 2.5 mo, $200?
Money better spent just buying (or not buying) btc here, IMO.

You kinda hit one thing on the head this is killing resale value of S7's.  And the interesting thing is it likely will effect all other miner's prices to.... which becomes interesting. 

So really good for someone buying a bunch of new S7's (assuming difficulty does not shot up insane).  But difficulty has become hard to predict.  They will sell though inventory though I predict at this price with coupons.  I did not see this coming personally.

I ordered several S7 batch 12.  Some of them came in with firmware dated March 4, 2016 and some of them came in with firmware dated December 3, 2015.  I have more Batch 15 coming in this week and will be interested to see what date of firmware is on them.

That highly suggests used hardware.  It seems unlikely they would have installed Dec firmware on a miner built more recently.

All of Bitmain's hardware is used, they don't sell anything that hasn't mined for them in one of their farms for a while already (and probably already ROI'd their production cost prior to resale).

guys I have to sell 16 coupons valued at 100 usd,
I sell them at $ 30 per coupon

[Dr Charles]

What is your ID on Bitmaintech's website? I will send the coupons for free at 1 per person. If you want multiple, $15 per coupon. I have 9 left.
