You are bidding on a used Bitmain Antminer R4. This unit is only partially hashing at aprox 3.9 TH of hashing power. See the attached screenshots showing the unit functioning. There are times where the unit will come on and has at a full 8 TH, but then it will drop back to basically 4 TH. One of the hashing boards was sent for repair some time ago, and is now functioning off and on. Because of this, the unit is being sold AS-IS. I will not accept a return on this unit for any reason. You may be able to send it out for additional repair, or find replacement boards here on eBay. We're moving away from the R4 units here, so we'd prefer to just clear the space for something newer.

You can rest assured we're a longtime, trusted eBay seller. Item will ship in original Bitmain packaging.

Unit mines Bitcoin, Bitcoin Cash, and any other SHA-256 coins.
