While I agree with both of you, neither of you actually said anything about how, you just rephrased my question in answer form. How can that bridge be crossed? And what do retailers have to do in the meantime?
It would probably have to be (in this order of likelihood): 1. Be profitable in and of itself 2. Cost less than processing other payments 3. Customer demand |

I really like the idea but looks like M$ Windows only app.  Yeah, I realize that, but that's the stuff I know, I'm sorry. If I had more time I would have figured it out as a Java app and if I had even more time I would have made it into an iPad app. Imagine this on an iPad or any tablet device. "Mt. Gox Trader Tablet Edition - Trade any time, any place"... If only I had the time... Switching to Qt or something else multiplatform may be easier than switching languages. iPad is a whole different world. |

So, would it completely not be worth it to mine with only 300 mega hashes/s? I pretty much just want to be able to make my money back...
It might be worth it if you already have the hardware. Buying it for mining won't. |

The most perfect place in the world to mine for bitcoins might just be Antarctica. Why? Because it has 2 elements in abundance needed to mine for bitcoins - a never-ending supply of freezing cold air, and endless wind due to the vast expanses of land with no trees or anything to break up the wind.
You also get ~6 months of continuous daylight. To take advantage of the freezing cold outside, use liquid cooling throughout all your rigs and have it all funneled to radiators outside the building (or just build your rigs in a shed outside - probably an easier method, though it would suck to have to go out there all the time). The only problem I'd foresee would be if there was an interruption in your electricity supply from the wind turbines and you had your radiators for the cooling loops outside the water would freeze in the radiators - very very bad. So it would be best for those of your moving down south to mine for BTC to instead just place your PCs in a shed outside the outpost.
You would still need a lot of humidification and air conditioning. Antarctica is a desert, and you don't want to go around computers with that level of RH. Also, you would need a lot of batteries to maintain your environmental controls, unless you could somehow get permission to drill into the soil for use as a heat reservoir. Now if you were lucky enough to secure a spot in an outpost there AND had somewhat limitless funds you could theoretically ship all the hardware you'd need to the base, and assemble it all. For electricity you could build small wind turbines. For internet just use 2-way satellite! And every once-in-a-while just buy more stuff off Newegg and have it shipped to your location.
I think you'd have to go through Raytheon for all of that. Maybe not... Or you could just mine in space. Even in earth orbit it gets several hundred below zero.
You would have some serious problems with the feature sizes on the chips compared to the particles they're going to be getting hit with, unless you find a way to lift an enormous amount of shielding to your station/with your satellite. |

Hi does anyone know if quad 6870 running on 890FXA-GD70 mobo is a good idea?
Sure, depending upon your requirements. It's a bit expensive if you are starting out now. I see most miners go for the dual card option instead of quad. Why is that?
Cooling. Cheap mobos. By having 4x card dont you save more on other hardware cost (no need for another set of mobo/cpu/memory) as well as less electricity?
You sure do. Is there some hidden inefficiencies in the quad card setup that makes them less ideal?
There is almost no clearance between the dual-slot cards if you have adjacent ones. You should get some PCIe cables or extenders or wedge them apart and get some fans blowing on them. |

Hookers are tangible services (you don't get to keep them).
skadoosh00 I would think the showing off would be worth 5 minutes.
If infrastructure were in place such that bitcoins could be exchanged similar to a credit card transaction, or payable by phone, how long does it take for an exchange of BTC to clear?
The new Android client (and possibly others) allow for NFC style payments, so it may be close enough. The transaction will appear as soon as the next block or two are found, but may not be confirmed for many hours. A day is a safe bet, depending upon your appetite for risk. |

HOOKERS!
Mostly curious about tangible goods rather than services. EDIT: Also, preferably not illegal goods. Hookers are tangible. It's the strippers that you're not allowed to touch. |

it would take at least several months to get your investment back. Even longer.
It's closer to "never". |

Can you use it successfully for its primary purpose, as a video card, perhaps in a different machine?

And I still wouldn't be out of the hole to buy new mining equipment to stay on top of the difficulty curve. Bleh.
Personally, I think you're thinking about buying the wrong equipment.  Optimizing based on the best Mhash/s per W, the 5870, and discount retail prices on equipment, running at 200W before the GPU load, you will need 1975 5870s @ $190 ea. and 395 base systems @ ~$421.97. Your CapEx will be $541,926.18 and your OpEx will be $591,694.20, totaling $1,133,620.38, to *gross* $70k/year. Your profit ratio will be 6.18%, and the *only* ways to get that up are to reduce your CapEx or not pay for the 3.9GWh. This is if you start *today*. If you could even supply power to this cluster, you would also have the warmest house in the winter and procure bonus tinnitus! I can recalc for 5830s/6870s if you really want. |

This mostly seems to confirm the old addage that linux is only free if your time is worthless to be quite honest. How much performance do you tangibly lose if you just use a windows box that works to whatever extent it works, but reliably so?
However, that is untrue. For the slow kids who have trouble using Linux, or using it without a windowing system, the time they lose would surely be made up during CHKDSK, waiting for Windows to boot, reinstalling software, reinstalling the entire OS when the registry is trashed, or reinstalling from whatever else is certain to go wrong. Anyway, the amount of time it takes to install, update, and manage even a small cluster of Linux boxes is miniscule compared to the same task with Windows. You don't need some fancy ghost imaging software, sysprep, or waiting to do manual installs. You just PxE boot everyone off of a single image, or dd a single image onto each machine and you're running when you finish your beer. Sure, you can mostly do that with Windows, but it's not going to be free and neither is all of the time it will take.  Setting up a single machine takes the same things it takes on a Windows machine: drivers, ATI Stream SDK, and a miner. You don't even need AMDOverdriveCtrl or RadeonVolt. |

even if you did, the difficulty increases would kill your production... 300$ a day one week down to 150... 75... etc...
Recent difficulty increase was just 13%, not 50% (or even 100%). And the next one can be only 8-10%. And it is possible, that there will be even some difficulty decreases. Profitability depends on price, not just difficulty. Recalculating for a consistent 10% increase only puts him $19,269.27 in the hole after a year. The price is probably already inflated, but being a little positive and putting it at $20 in six months makes it $16,018.39 in the hole. Basically, in the hole. |

By my calculations, this will put you $49,097.04 in the hole after a year.

Also, I’m not exactly sure how the work gets allocated to the GPUs but it seems like copies of the same Bitcoin server running on each rig won’t be able to coordinate work division between all your GPUs so you could end up with wasted hashes.
If they are separate servers, each having a unique wallet, there would be no duplicate work as the block chains will be different on each server. |

Can bitcoin clients running on several home PCs get access to the same wallet and transaction database via a fileshare?
Bad idea. I want the same wallet on all my PCs and I do not want to re-download 135000 blocks on every single one of them...
Clients or servers? Clients can access your single server with JSON. If you want more servers, you can either copy the block chain database, the wallet (really not a good idea, either ), or point new installations to your existing local server. They will download locally from that one. |

I have a couple of scripts that I use to keep my workers on the BTC Guild server with the lowest load (available for all, see my sig), but they poll the JSON endpoint. Unfortunately, it returns a busted result (missing closing curly brace) for the workers if you haven't returned any shares in the current round. Maybe if I'm lucky, that missing brace could be put in there soon. I have a few other API improvement recommendations, as well, if suggestions are welcome. |

any suggestions or help would be much appreciated
Sounds like a Crossfire thing. Did you call Microsoft Support? Does it work under Linux? |

Sounds like fraud to me. Keep your business honest people, retailers have to make a living too.
I don't really support that method, but they did jack up the price. Also, "customer satisfaction" wasn't met since it turned out to be a card that did not meet his needs within in the allowed timeframe, so it's quite returnable under common considerations. |

Have you tried the Support link at the bottom of their page?
