Proof of rigs and ownership will be via signed address on P2Pool where the rigs are mining now, and transfer of ownership via email to the user hosting the rigs.
So, you don't physically have the rigs. Are you selling them as a hosted package...is hosting paid for in the cost?
Is shipping not included in the price you ask?
In the event that I want to host them myself...would you accept escrow until the rigs arrive? If not, it's really too easy for you to scam people.
As I said, they are hosted remotely, so, no they are not in my physical possession. Hosting is paid for for this month only. It averages about $46-48/month for the 3.150GH.
Again, let me re-iterate... I will email a bill of sale to the buyer and make arrangements with the hoster to transfer ownership of the rigs. Period.
As far as scamming people, maybe you didn't read the post. My rigs are hashing on P2Pool. You will have the public address and I will sign with the private key to prove ownership as well as move them to a pool account under your control to further prove ownership. Before any transfer of funds, we will roll in the hoster to the email thread to confirm he is ready to transfer ownership and upon payment, I will notify him of change of ownership. The hoster will be the trusted third party. If you don't like the terms, you need not buy them.
BuckRogers (one of the people admining this section) will vouch for me. I've handled large BTC transactions for him and others as an escrow agent myself in other transactions.
This is the last response I'll make publicly in this thread. If you want to discuss terms or pricing or anything else PM me. I'm sick and tired of all the trolling from the tire-kickers.
