Searching co-investors for mining cluster

[LiquidMiner]

I'm searching for co-investors for a mining cluster. Instead of investing in your own rigs which are noisy and needs a stable internet connection, invest in a cooperative project!

The cluster will be based on 2xHD6990 per rig and this can be expanded to as many rigs as possible. Income of the rigs will be divided between buying more mining rigs and paying out dividend for each of your shares.

Current spec for a rig, may be subject to changes:
FD R3 Chassi
Corsair HX950W
2*HD6990
Asus P8P67 Revo 4*PCI-E x16 (2 in x16 mode and 2 in x8)
Intel i3 CPU

Internet connection: 100Mbit with unlimited contract

This will give 1,5GHash per rig at a cost of ~4000BTC. At current difficulty it will mine 18.3 BTC per rig per day or 6679 per rig per year. This means that ROI (Return of investment) after fees will be as high as 75%/year.

I will also investigate in the possibility of adding two 6950 or 6970 to each rig, giving about 700 MHash/s more. (This will need a larger PSU)

I will take 10 BTC per day in fees for power and internet connection.

Minimum investment is 100BTC.

Contact me via pm if interested.

We will be launching a bitcoin stock exchange in less than 2 weeks, you can use this to get your capital if you can wait. It will seriously cut down on administration with investors and remove the need for a minimum investment.

I may be interested but this is your first post it would be foolish to send a non revocable payment.  What assurances could you provide?

Do you remember about difficulty adjustments ?

Hmm, may be I should offer such mining contracts too... :)))

Maybe I can migrate to the SE when it launches? Will there be any fees for getting the capital there?

I see that, I am a Swedish M.Sc. student and are not here to fool someone. It would be foolish of me to fool you, since the big money isn't the money you invest but the money the rigs will mine. I'll invest 500BTC in the project to get a share myself of this money.

Of course I do, that's why i wrote "at current difficulty". Either me nor anyone else knows what the difficulty in the future will be.

very good idea! especially when every cost will be in BTC  

my rig proposal (in general):
1200 w psu (a simple one with a big warranty)
3x6990 or 3x5970 (hard to find)
more gpu per rig = more rig efficiency 
cheapest dual core cpu and mobo with 3-4 pcix (x8,x4 or x1 don't make any difference)

does seem a mite high
can anyone spell SCAM

indeed. $10 a month sounds reasonable, but $10 a day is super expensive.

electricity costs (where i live) $0.10 /KW/h. so * 24 = $2.4 per day.
it's not necessary to have high speed internet, so a cheap DSL line (@$30 a month, $1 per day) will do. you can probably have multiple machines running on the same line, because bitcoin mining isn't bandwidth intensive, so it's probably less than $1 a day. that leaves ~$6 per day for managing the servers, which is pretty expensive considering setting up mining rigs isn't very hard.

[zoro]

this fee thing is not very clear and it caused misunderstandings!
i understand that it is 10btc from the total btcs from all the rigs/per day
but this should be changed every time a new rig is added or electricity goes up!

[travex]

Sorry for hijacking but if I'm offering free electricity cost for co-miner Liquidminer in case youre interested ^^

@zoro : how many btc per day you get at the pool mate ?

[zoro]

travex: 12-14 (current difficulty)

each hd69900   is 375W thats 750 for 2
how can you add TWO 6950 or 6970 (aprox 140W each) to a Corsair HX950W power supply

more sales hype

The cluster will be based on 2xHD6990 per rig and this can be expanded to as many rigs as possible. Income of the rigs will be divided between buying more mining rigs and paying out dividend for each of your shares.

If you're really serious about a cluster, you should use a PCIe expansion chassis designed for GPUs, which can hold 16 cards rather than a bunch of separate computers.  For example, the Dell PowerEdge C410x.  It works with ATI/AMD cards as well as NVIDIA cards, and can plug right into any computer to add 16 PCIe slots.  In a 42U rack you can easily fit three computers, nine of those, and a power distribution unit and you'll find yourself with 144 6990's--which is somewhere around 100 billion hashes per second.  All for a cost of under 140 000 BTC.

You guys calculate right, electricity costs are about 2.5$/rig and internet are about 1$ (Yep, 100Mbit is cheap in sweden). With 2 rigs this becomes 6$ which is obviously less than 10$. Why then charge 10BTC?

Neither my internet provider nor my electricity provider allows me to pay in BTC. Therefore I need to exchange those BTC to $ which with current rate will be 7$ - paypal fees = 6$. With one rig there will be some extra $, but the 10BTC was more like a guideline of the costs and not what I am taking as profit. I hope some of you one day see this good enough to donate to my personal bitcoin account instead.

It's 2 GPUs per rig. Adding 2 more GPUs would be adding one more rig, which would include a new PSU.

That's not how I read it
And WHY would you add lower capability gpu's

Sorry, no, you're right. I'd missed the part about the non-6990s. However, both you and I missed the part about the larger PSU for the 6950/6970s.
