This is my last 5 early batch antminer s9's that are 12.93 th/s. These are between 5 and 6 mos used. I have these in hand and will ship out by next day if not the same day as purchase. Shipped out priority mail. These miners have had no issues. Have been cleaned out twice suggesting a clean out every 3 mos. They will be cleaned out before leaving and rechecked to make sure they are running properly.
Price:4 btc including psus & shipping ( North America).
