0.2 J/GH was what Gen 3 asicminer chips were simulated to achieve at 40nm but unforeseen heat problems in the design were encountered in actual chip testing. Friedcat stated that these heat problems were solved going into Gen4 so I guess we will have to wait and see in both cases. Whatever happens, we'll have interesting stories to tell the great grand kids while rocking on the back porch. 0.2 J/GH would be amazing. 0.2 J/GH + liquid cooling from DataTank = huge hashrate |

The Bitcoin network protocol was designed to be extremely flexible. It can be used to create timed transactions, escrow transactions, multi-signature transactions, etc. The current features of the client only hint at what will be possible in the future.

Doesn't matter what the J/GH is if you can never recover the capital cost of miners even with free electricity, which is where bitcoin mining stands right now.
nah, 350$/btc is still much better than last year. ... and difficulty is MUCH MUCH better than last year. Nothing to compare... |
Under development Modular UPGRADEABLE Miner (MUM). Looking for investors.
Changing one PCB with screwdriver and you have brand new miner in hand... Plug&Play, scalable from one module to thousands.

You couldnt be more wrong. Here is a chart for you:  It shows the network speed where miners would break even after 2 years using the listed assumed variables. Even in the current climate and with current efficiency, we are no were near where (industrial) mining would not be profitable. And the effect of power efficiency is quite dramatic if you consider reasonable electricity cost price ranges (~0.06 / KWh) |

Spondoolies is advertising $650/TH ... for a pre-order. And my understanding is that other producers are even more expensive? At which price per TH does it not become profitable to mine anymore, even if you get free electricity? |

Its not because they are asking that much to individual miners and their costs are anything like that. Even so, if we were to calculate with $700/TH, we get this:  |

ASICMiner isn't selling at $330/TH/s. Their product is $330/TH/s, but that's not an installed and hashing price. That's a little pessimistic in some ways, and optimistic in others. First, I'd set the break even period to ~650 days, which is about 93 weeks. That's about the time the block reward is going to drop to 12.5BTC, which baring a major shift in the price or hashrate will make everything unprofitable. If price doesn't move, I would suspect we would see all the hardware in the pipe get flushed, but not a lot of new wafer starts after that. It's already incredibly tough to move hardware, and without pre-orders investing the money in 500PH/s worth of wafers is quite risky if you're looking to sell them at close to marginal cost. My gut is that baring price movement we see another doubling to ~500PH/s in the next few months, and then maybe some slow movement from there. Going much beyond 600PH/s or so is going to take someone producing an awesome new ASIC that can get decently better than 0.5J/GH and $250/TH/s though, IMO. |
