ROI Plot and Concerns for Future Price

[Smarter]

I have dabbled in Mining for around a year, here and there for use on a certain Tor Network Site . I currently have a automotive shop I rent, with unlimited power for Free included in the very small monthly fee, and I have 1200sqft of space. As well as 3G in the area. I would like to invest into a mining rig that will give me enough monthly income to pay the monthly fee for the unit ($275.00 USD / 61.6895 BTC - Monthly). Heat is also not an issue as the shop is in a valley and is dehumidified but not heated, and stays in the 60-70's during summer and is currently about 40's at best, so heat would be appreciated even.

Current Setup:
HD5770 OC 960/600 - 207.5MHash (Avg)


I would like to know if anyone could help me with a build that would produce 3075~ MHash/s for as CHEAP as possible, regardless of Power or Heat!


Thanks,
Smarter

The power you would need to use would get you evicted from said shop after the bill comes in. This isn't even a real currency and not protected by the government, do as you will but anything unprotected is not a good thing

how many apple 2's do you need to run that many accounts?

Actually, you'd be surprised, we get our power from Niagara Falls, power is stupid cheap here. I have a 120/220 Line, Unlimited Power . I'd think Welders and such would pull more power than a 3k Mhash rig?

How do u get so many each day? I get like 0.0400 a day with my 560 nvidia

Dual FPGA X6500 Mining Card but expenisve gets 300+ 600+ m/hash

Is there really cards for mining?

Really? What does mining actually do? What does it calculate.

You're doing mathmatically computations to either verify create a new block of 50 Bitcoins or computing if the signature on a transaction is valid. Basically each bitcoin has a unique ID and the transaction creates a hash that says you are allowed to transfer the value of the bitcoin to someone else. The rest of the community verifies the said signature to verify that its valid.

There are fixed number of bitcoins possible to be created and as time goes on the effort to produce additional bitcoins becomes more and more expensive. As you see the number of bitcoins produced going down you'll start to see the transaction fees and such go up.

I wouldn't invest anything that I wasn't willing to lose...At these difficulties you're going to need some pretty beefy rigs to produce enough to pay your rent.

Take a look at:

You're probably going to want to go with an MB with 4-6 PCI-e slots and then get adapters so you can fit the cards on the board. You don't need much for a processor so just go with a cheap dual core AMD board. You'll also need a big power supply probably 1000-1250W if you are running 4+ cards.

Not sure if buying mining rigs is even that economical with the lower price of bit coins...I haven't seen a break down lately.

With the existence of PPS (Pay Per Share) pool mining, I do believe that the return could be somewhat calculated. I have created a Spreadsheet with very extensive and detailed information. I would like to create a "minimum expectancy" Rig. In essence, if I invest the money into a Rig and calculate it at "near worst case scenario", I am giving my self an opportunity to profit off my shop. Simply put: By investing in a Rig that can produce at minimum the monthly cost of my shop, then anything over that minimum is profit. (As I would already be paying for the shop, with no return). The rig itself is also able to be liquidated in the event of issues.

I don't get how i get the bitcoins, and how do i see how many i have etc

How long do i need to run etc etc Can anyone explain
