At $1,150.00 per set, you are far below any price Bitmain has ever sold directly to the public. So we can only surmise that you are losing money. So be it. I will buy 30 S9/PSU sets at $987.50 each. I will pick them up at your "Chicago Location". Please post that address. I will make plans to go there. I will NOT send you any funds until I arrive at the pickup location. Cash and carry.  I assume you're fine with that?
