If you're legitimate then how about this, give me access to your Bitmain account - I will then pay for the full order and we can escrow the amount of BTC you're asking for control of the account. Once I confirm the order is paid and will be shipped to me through the account (which I will retain access to until the units arrive) the escrow will then release the BTC you're asking for to you.
Sound fair?
Sounds great. I am confused on one part, Escrow has to release the payment as soon as Bitmain changes the address to your shipping address, not until they are really shipped. I can't wait until November. You pay the amount to bitmain , raise an address change request and then after the address is changed, the deal is complete.
