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
Month | BTC | USD |
1 | 30.6 | $520.2 |
2 | 10.04 | $170.68 |
3 | 3.29 | $55.93 |
Total | 42.93 | $746.81 |
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
-$1017.24I decided to look at it with a mining pool and this is what I found.
Current RoundTotal 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 |
1 | $520,216.10 | $545.83 |
2 | $170,639.54 | $179.04 |
3 | $55,972.67 | $58.73 |
Total | $746,828.31 | $783.60 |
Given this minuscule $36.79 increase, I'd still be
-$980.45Having 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:
