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 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 |

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:
