I am interested in buying a dropbox coupon code for 25 or 50GB.

Payment via bitcoin or paypal with escrow unless you have a reputation here or ebay.

I am looking to buy Ztex 1.15y boards and possibly other dual/quad FPGA boards.

Let me know what you have and your asking price. Please note that I have a rather limited budget, since this is not for a cryptocurrency ROI-ing project.

I can pay in BTC or via paypal. Shipping would be to the EU.

[$14,500]

I would like to sell my KNCMiner Neptune preorder from batch 2. Order number is 139xx paid by wire transfer on Dec 3rd. My guess is that this is in the first 25% of batch 2 orders.

Starting price is $14,500 in increments of $500.
Auction end time: Dec 23rd 23:59:59 UTC

Accepted payment methods are: bitcoin & wire transfer.
No escrow is available for the order value of $13,200 due to the extended wait period, however I should be able to provide enough information to prove my credibility. Escrow is available for the amount above what I payed to KNC.
Payment deadline: Jan 3rd 2014 (taking into account holidays. extendable if deposit is provided)

I am not sure if KNC can transfer orders or change shipping address to a different country. I am assuming that I will need to reship, so buyer pays for shipping from Poland, EU. I should also be able to provide hosting for the miner.

Good luck bidding and may Santa Clause reward the winner appropriately afterwards.

I'd like to check with someone more experienced if my thinging is correct.

Let's say Alice paid Bob for a GPU via BTC. I would like to repurchase the GPU from Alice, but I need to be sure that she bought it Bob.

That said, is it technically and otherwise possible that I request Alice to sign a message that would prove that her wallet address sent funds to Bob's wallet?
