Used miner purchases will receive coupons towards new miner purchases
Although this current batch of Antminer S5 listed for sale are used units, Bitmain performs quality control testing on every machine to ensure that it is in proper working order before shipping to consumers.
These machines have only been running for about 40 days in our farm, so there should not be a significant impact on the performance or the total life of the machines.
Bitmain would like to offer coupons to customers who bought S4+ or S5 recently to be used towards the future purchase of our next generation of mining machine.
At this time, we are unable to provide detailed information on the new machines or the size of the coupons, but please expect an official announcement in the near future.

Thanks for the update! And thanks for extending the 15-day warranty on these "second-hand" S5's to 30 days! It makes them a little easier to sell :-)
By the way, just a little English-language suggestion: PLEASE stop calling these "second hand" -- that term has very negative connotations in English that you would NOT want associated with your products: the term is usually used to describe worn, damaged and degraded items (usually clothing or furniture) that have been passed down person to person (or generations of a family). Second hand goods are typically given way for free to the poor or sold for a fraction of their original price.
The professional terms used in the electronics industry for used devices that are tested, maybe-repaired and resold by the original manufacturer are:
- "Factory Refurbished"
- "Factory Certified Returns"
- "Open Box Items"
and it's also standard in the industry to offer the same full warranty on such items as new good, to assure buyers they are just as good as new!
The second hand term I think is proper, as they have been running up to 40 days. I think they handled it well at this point though with that post. If they would have posted day one would have been better. I suggest next time launching a sale like this and info at same time.
Below is why I don't think other terms are proper
- "Factory Refurbished" - these are still working miners they were not refurbished, just checked for performance. I see refurbished going in re pasting, making it just like it was brand new.
- "Factory Certified Returns" this they are not returns it is from data center bitmain owns so again sounds good but not acccurate
- "Open Box Items" Open box goes to where it does not tell much and these did not set in a open box they were on a rack running.
I think second hand is very fair term, and they have now done a great job explaining it.
they would be stupid or something
. it works but when it wants to and only one blade the other blade is for sure dead, everything else works on it etc .
