As already said in the OP:
- Please don't bother to send offers below 55 BTC
- Send serious offers via PM, so I can discuss details
Thanks.

BTC25 if you will escrow

many stores sell products that are exceeded then not even manufacture and not delivery at a gold price

and alot of people buy products that are exceeded before delivery start

You realize that at 56 BTC anyone can just get a Hashfast unit and be done with it.

sorry but 128GH/s is only worth about 25BTC at most... considering KNC's 100GH/s is 2k, 20 BTC... and uses 1/6 the energy your equipment does.

So I'll meet that in the middle...

23 BTC offer.

By the same token, is it realistic to assume you will see a 130% increase every two weeks? I just don't think so.

54.86 if you mine 24/7 and in reality it s not possible.

20 weeks for win nothing and directly to trash

i dont understand why buy this

I'm going to chime in because I don't understand your math. If lived near and had 55 BTC to my name, I think that would be a fair price for this miner.
Say you paid 55 BTC and started mining at the beginning of the assumed 30% higher difficulty than today's 50810339.0483, which is 66053440.76279:
(Each two weeks I'm assuming 30% higher difficulty, which I think is an extreme prediction to make over a long period of time)
Week 1&2 generated: 13.64
Week 3&4 generated: 10.5
Week 5&6 generated: 8.08
Week 7&8 generated: 6.22
Week 9&10 generated: 4.78
Week 11&12 generated: 3.68
Week 13&14 generated: 2.82
Week 15&16 generated: 2.18
Week 17&18 generated: 1.68
Week 19&20 generated: 1.28
Add that up, total = 54.86 under the extreme assumption that there will be a consistent 30% rise every two weeks.

Assuming a 30% difficulty increase per two weeks average in 500 days.
Though Hashfast, Kncminers, BFL 600 GH cards all coming out.

ASICminer putting in much more power. The network is going to go up really fast,
and very quickly. ROI will never happen with an offer of 55 BTC.

The thing is if I were to give you 55 BTC right now you have it in YOUR HANDS now.
But for me I would have to wait years to get anywhere near.



No one cares about what you payed for, if you payed $1000 for something and its worth $100 now, your can't put your personal
loss upon others.


Assuming 30% - Per two weeks.

[This was also x-posted to the German board.]

I'm selling my BitBurner Miner with 16 boards, one of the first miners from burnin.

Please note:
- This is not a public auction. I reserve the right to not sell the miner if I don't find a suitable buyer.
- I'm taking offers via PM. I'm only selling for bitcoins and only to trustworthy persons.
- This offer might be interesting for professional miners who want to add another miner to their existing cluster. Mining newbies should definitely think about the problems I'm describing below.
- The miner is located in Europe, Austria. Local pickup at my place would be preferred, but shipping is possible if required.
- Your questions are welcome, but please read the whole post before asking an already answered question.



The miner

Here's a video of the BitBurner in action: http://www.youtube.com/watch?v=3CRz5AC3cZM
Currently boards are running overclocked at 8 GH/s (430MHz, 1.3V), this is a total hashrate of 128 GH/s. Total power consumption (miner, 2 PSUs, Raspberry Pi) is at 1550 Watts.
This video shows cgminer running for an hour: http://www.youtube.com/watch?v=ZQIEhzIRzgg

According to burnin, you could run each board at 9 GH/s (source), which would be a total of 144 GH/s. To stay on the safe side I did not try that though.

Why are you selling?

In mid April I ordered 320 Avalon Chips at Zefirs Groupbuy. I did not think much about the implications of running a mining device. Now that I have the BitBurner for over a week I ran into these problems:

1. Required space, heat and noise
Currently the device is in my apartment. That's ok for a couple of days, but (as I had to learn) definitely no long-term solution: the miner is generating heat and the fans are kind of noisy. So I think this device would be great for someone who already has a dedicated room for miners.

2. Time expenditure
I received the miner one week ago and since then I spent my nights configuring cgminer, testing different pools, measuring temperatures etc. etc. Also, the miner should run 24/7 so it needs to be constantly monitored. All this just takes up too much time for me.

What is included?

The complete setup as seen in the picture above (exluding the extension lead and the ethernet cable):
- 16 BitBurner XX Boards (20 chips per board)
- 8 fans
- 2 x USB cable
- 2 x CAN cable
- 1 x PSU EVGA Supernova 1000 G2
- 1 x PSU Cougar GX 1050
- various screws and bolts
- 1 x Raspberry Pi (Model B), 8GB Micro SD, case and power supply

Installed on the Raspberry Pi is cgminer 3.3.4, you just need to plug everything in and you can start mining immediately.

Shipping / Pickup

Local pickup definitely would preferred by me. Shipping is possible, but you would have to pay shipping costs. Also, I'm not sure how to do proper escrow when shipping a miner like this. If there's a suitable solution let me know, I'm open to your ideas.

Price

You definitely should do your own research to get an idea of how much income this miner can generate over the next couple of months.
If you're interested, send me a PM including the maximum price you would pay and I'll put your offer on my internal list. Please don't bother to send any offers below 55 BTC (this were my initial costs).

Are you selling single boards?

No, I don't sell single boards. However, the miner consists of 2 separate 8-board towers, so I might sell these 2 towers separately (including one PSU each). But I'd prefer to sell the complete miner at once.

Any other questions?

Let me know if there are any other questions, I'll try to answer them in the comments or via PM.
