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.
