I got them when buying Antminer S9. As you want to use them, I do not know. Screen video can send to someone who is interested
I do not answer the forum. Communication via telegram or skype
You can not use it when purchasing S9.
You have a coupon, why do not you try, which miners are suitable for?
And the telegram here is more for a Scummer , than honest sellers.
The question the same.
Can 500USD coupon be used, when purchasing the Antminer Z9 mini?I do not even offer a price before this answer, because I do not want to buy Antminer E3 or Antminer X3, which you can definitely buy with this coupon.
