For sale: Bitmain Antminer S1 Dual-Blade Bitcoin Miners

Used with care and in perfect working condition

These units were operated by us for the past 8-10 months. They are extremely stable rigs, with zero issues, able to mine any SHA256 coin (including Bitcoin, Namecoin, PeerCoin, CureCoin, DigiByte, Deutsche eMarks and hundreds of others). They are standalone, which means they do not need a computer or Raspberry Pi to control them and they can mine non-stop 24/7. They even restart on their own in case of a power failure. You only need to provide a suitable power supply (minimum requirements are 500W / 80+ Bronze rated or better power supply for best performance) and an internet connection via ethernet cable or WiFi. They are configured easily via any web browser and each one can have a unique IP address (so you can run multiple rigs).

This is the world's most stable Bitcoin miner!
