Sell several Bitmain Antminer A3. 650.00 Euro each. Payment BTC, BCH, RIB, ETH, LTC or Cash.
Pick up Cala Pi. I have several to hand in for moving and no more parking space for it. On purchase of all devices (10 pieces) I go down to 550,- Euro per piece. You need a 1600 Watt power supply (available at eBay or Amazon).
