Have you worked out the very ~ lifetime ROI on this?
I ask this question as I am currently under the impression you will only get back a fraction of its costs (and would like to be convinced otherwise as I have cancelled a dedicated machine I had on order)
My previous calculations weren't correct. I hadn't realized the extent that the difficulty increase would cut into profits. I am canceling my order now
But to answer your question, at 2 Ghash/s at $17
And with the $91.59/month in electricity costs, I'd be left with about $472.04. So finally after 3 months I'd still be -$1965.57.
This would be only marginally worse if I resold all of the hardware for 40% of their original value, $948.33. Then I'd be -$1017.24
I decided to look at it with a mining pool and this is what I found.Current Round
Total Pool Ghash/s 1906.47
My Ghash/s 2
Pool Shares 201,669
My Share of Shares 211.6
Estimated Growth 45%
USD Rate $17
|Month||Pool $||My Share|
Given this minuscule $36.79 increase, I'd still be -$980.45
Having seen these numbers, at this point in the mining game you'd be better off starting a mining pool to compete with the big ones. This particular pool, if charging a 2% use fee, would generate +$14,936.57
in 3 months!!!!
Now that's where the real money is at.
To make these calculations I used this calculator: http://striketeam.ath.cx/btccalc/btccalc.php
And I used the numbers from this mining pool: http://mining.bitcoin.cz/stats/
Check em' out!!!! They're both pretty cool
