1 unit for 100 BTC using escrow and I'll cover the overnight cost to ship the unit from the datacenter to my location once it arrives there.
If all goes well I will buy the remaining units within 3 business days of receiving my first one and I'll pay the same 6500 for each of them.
Your offer is below my opening price, plus I don't have any way to be sure that you will not claim to have received an empty box from me. Other than this, 10btc of difference for being in batch 2 instead of batch 3 is really ridiculous and I want a btc fixed price, not depending on usd. I was offering the same 5 units for the same 150btc each one month ago while the price was 30$/btc.
In other words, thank you, but no, thank you.
