Fully working antminer u1! These little powerhouses hash between 1-2ghs with very low electricity consumption. They are extremely beginner friendly and a great way to start home mining at a low cost. Perfect for solo mining and projects. If you are looking for more hashrate I have an antminer s9 listed in my other auctions! Miner shown in pictures is the exact miner you will recieve. I'm also throwing in a free flexible usb fan! Original box and packaging included.
