The fan is 320W, but the chip is only 250W, or less (probably a lot less) If a chip uses 250w of electricity and gives 250w of heat, that means you have a chip with no hashing power. The cooling capacity of the fan (320w) is the amount of heat it can deal with. Not the amount of electricity consumed by the chip. Not sure if serious? All (or 99.9999999% so we can just say "all") electricity used by an electronic circuit is converted to heat. A chip does not real "work" (in the physics sense). Law of conservation of energy. If 100W (electricity) goes in then 100W (heat) comes out. |

what satoshi premined 4 million BTC? thats a joke right?
Yep He premined 5 million BTC, not 4 million  Learn the definition of premine.. He did not premine it. He was the sole miner for quite some time. He wasn't even the sole miner. Hal Finney reported mining one of the early blocks (IIRC it was in the first hundred or so). So the best one could say is Satoshi was one of the few early miners in the first year of Bitcoin. |

First glance, this looks like a reach from some bummy btc users. Problems with $30 worth of btc?
I'm not one for scams or losing money and all that, but BitInstant was having a lot of trouble and they were seeing an overwhelming rush in transactions and users. It's like jumping onto the highway during rush hour and wondering why you can't get to where you need to go in 10 minutes...What do you think is going to happen? These are new companies using new technology and running into new obstacles, they don't work magic. How can we move forward as a community when we need to constantly take two steps back due to impatient, incompetent users?
(I could have totally missed something with the whole BitInstant debacle so bear with me if so).
Many class action lawsuits are over relatively small transactions (though you chose to mention the lowest transaction amount shown in the complaint). It is a significant suit, however, because class action status means that every person that the court determines was damaged by their actions will be awarded money (the people that the court determines to be in the "class" of people that were damaged). The court will base this on Bitinstant's internal records, and would likely affect to a significant percentage of transactions that occurred in 2013, which is likely to be tens of thousands of transactions and millions of dollars in damages. Filing as a class action doesn't yet make it a class action. The courts need to certify the class and unless you see a public record that it has happened then that is the first line of defense. Companies will routinely bring out the bring guns to prevent certification as a class because while the lawsuit can go forward it will go forward as individual claims. |

Well why on earth would anyone new get into Bitcoin? The value prop is disappearing. The mining goldrush is ending. There is, however, still strong reasons to get involved in bitcoin as a value store, and method of value transfer. If mining disappears, so will the bitcoins...It will take forever to confirm even the smallest transaction. So if you plan to store value in bitcoins you better start mining. That's not how it works. The difficullty adjusts. It will always take an average of 10 minutes to confirm a transaction, as long as there is at least one CPU hashing somewhere. This. Within reason. As long as the decrease isn't something like a 99.999% drop overnight the network will adapt. |

Am I not the guy who invited an attack? Nobody cared enough to attack it. It was worthless from the day it was created and the few clueless "longshot" miners are finally just giving up. |

Just cause an idiot like you can use google and find one mistake per 100 posts, you're a big man, now? One mistake in a 100 posts? Please. Anyone can find 100 mistakes in 100 of your "posts" (if you want to call made up rambling nonsense "posts"). It doesn't make them a big man, it is pathetically easy. You know how someone knows Vlad is wrong ... he is talking/posting. |

FYI: the fed's 99 year contract to print dollars just expired so its pretty convenient that Bitcoin Just happened to be here and to go buck wild all of a sudden for no obvious reason. a) the federal reserve act has no expiration date. b) it isn't a contract. The federal reserve act grants the fed that authority until such time as it is revoked (like any other law) by Congress without any consideration in return. c) how about you actually read rather than continually make up shit: http://www.law.cornell.edu/uscode/text/12/chapter-3TL/DR: your an idiot. |

Bitcoin have almost constant 3600 coins generation per day, but the global gold production expanded a lot during recent years after the gold price rally. Although total amount of gold is limited on earth, the daily production is flexible, that's the reason gold price can not rise as fast as bitcoin, since when price rise too fast, the production will increase. Not really. While gold production is elastic (can increase in high prices and decline in low prices) there is a LOT of gold already out there. Gold production is about 2% of existing above ground supply. So even gold companies going crazy and doubling production only means a 4% year over year increase in the available supply. The good news is Bitcoin is seeing a similar effect. As the number of coins minted increase and the daily production decreases the effect of newly minted coins has less and less of an effect. Unlike gold new supply is still rather meaningful (supply is being expanded by ~10% annually right now) but over time that will only decrease. |

Where are you getting 600GH from??
From what I understand, the current board design does not lend itself to substantial overclocking. I would not bank on that
in your ROI evaluation.
Apart from the 600GH/s nonsense, this is one of the better ROI evaluations I have encountered recently.
If you can call it that, considering it was done based on 1.5X the expected hashrate
surprised so many people dont like the 600GH number, that was one of the easier assumptions. BuzzDave has said multiple times in this thread and even their website indicates the chip is capable of 2.5-3GH per, the $8000 kit has the per chip hashrate at only 1.5GH. At 600GH it's about a 50% increase from the kit description which rates the chip at 2.3GH per - i thought that was a very reasonable assumption. Or are you guys saying 600 GH is too low and i should increased the hash rate is even higher in the calculation? Not clear.. and just how are you going to overclock it with every piece of it at it's limit? liquid nitrogen? voodoo? Getting the heat out appears to be less of a problem then getting the power in. Even the S-HASH custom board runs without a heat sink despite a significant (but nowhere near close to 50%) increase in clock. The question is more like "how are you going to get 50 amps out of a 30 amp PSU". The short answer is you won' unless you want to see some sparks and a puff of smoke (one time only). |

At 600GH it's about a 50% increase from the kit description which rates the chip at 2.3GH per - i thought that was a very reasonable assumption. The CHIP may be capable however the BOARD is not. The board takes a 12VDC input however no chip runs at 12 volts, so the board has a regulator (DC to DC power supply) which steps down the 12VDC to the 0.8VDC used by the chip. Like all electrical components it has a limit on current which IIRC is ~30A. That component can't handle the amperage necessary for the overclock and overvolt you would need to gain a 50% boost in performance. It isn't ever going to happen. Even 10% overstock would be pushing the power handling capabilities of the board close to the limit. It might work, and you also might destroy it in a couple of weeks too, or maybe 10% is fine but 12% will kill it. Still 50% is in imaginary land where circuits can use unlimited amounts of power without issue. The board just wasn't designed for that kind of electrical/thermal load. Even a custom built board (S-HASH), designed from the ground up to get more performance out of each chip, which has a rather "beefy" 50 amp DC power supply still doesn't get a 50% gain over stock. To get that much performance out of the chip would require using larger DC power supply AND less chips per board and more boards. In other words buy a reel of chips and start designing something better. |

Wow nice. I doubt he will get the option to enter but nice to see some in the industry realizing Bitcoin isn't going away.

How many threads do you need? https://bitcointalk.org/index.php?topic=273804.0You should not be contacting IAFCU. It would be like I have an account at Wells Fargo and I owe you some money so you call Wells Fargo demanding they send you the money I owe you. How productive is that. Despite the fact that IAFCU is handling the actual payment processing they can't simply hand out money to anyone who asks for it. The payment list comes from bitfloor. bitfloor owes you funds, bitfloor needs to advise IAFCU to make a payment to your (correct) account. 1) Bitfloor owes you the money. You need to login to bitfloor and request a withdrawal. 2) Bitfloor needs to tell IAFCU to make a payment. IAFCU (like ANY OTHER BANK ON THE PLANET) isn't just going to send you moniez because you email them. 3) Unless you are opening an account w/ IAFCU there is absolutely no reason for you to contact them. Anymore than you would contact anyone else's bank directly. 4) You continually harassing the wrong person makes you an ass and probably is making IAFCU regret getting involved.

Exactly. The "prettiness" of the case has to be about the stupidest complaint for any industrial device. Personally I would be happy if any ASIC manufacturer just delivered boards. A board in a ghetto rack hashing today is worth a LOT more than a board is some pretty backordered case which will ship in "two weeks".

When I was looking at the block info for the very first block, the "Genesis Block", I check the address where those first BTC50 went. It obviously it belonged to Satoshi Nakamoto. Apparently that address is still in use. And according to a transaction, a person sent a fraction of a mBTC to that address under the bitcoin-otc name Konichua. Any thoughts? https://blockchain.info/address/12c6DSiU4Rq3P4ZxziKxzrL5LmMBrzjrJXPeople send coins there all the time. The address is public knowledge anyone can send coins to any known address trivially. This doesn't provide any indication the person sending the coins knows Satoshi or that he is even alive. Now someone SPENDING coins from some of the early blocks (genesis block is unspendable) that would be pretty interesting. Someone spending from an address known to be owned by Satoshi well that would be huge. |

You would need to contact Bitfloor not IAFCU. IAFCU is essentially just a "bank" (credit union) providing an alternative method to cash out. You can cashout to an existing bank or you can open a new bank account with IAFCU and cashout there. Regardless the cashing out is done by bitfloor via the bitfloor website. IAFCU is just a place to "send" your money.
If your bitfloor account shows $0 balance (because it incorrectly thinks you have already received the $300) there is nothing to "cash out" to IAFCU. Since you are under $3K limit and have a valid bank account there is no reason to even open an IAFCU account regardless. No part of the solution involves IAFCU so please don't keep bothering them, they are processing hundreds of real withdrawals.
1) Login to your bitfloor account.
2a) If the balance available is still $300 just make a withdraw request (this time w/ correct info).
2b) If the balance available is $0 then you will need bitfloor to fix that.
The bad news is if it shows $0, bitfloor has been essentially non-responsive to email so it may take a "while".

a plus is that confirmations will be in seconds now with miners running on asics
the whole point of the difficulty adjustments is to ensure that new blocks (confirmations) are generated at a rate of one every 10 minutes, no more, no less, regardless of total network hash rate. Was there not a point when the hashrate actually caused the block rewards to come quicker than was anticipated by the network? I had found an article a few days ago but cant relocate it. Must not have been signed into my google account at the time or they'd have archived my history. If hashing power rises rapidly within one adjustment period (2016 blocks ~14 days) then the time between blocks can temporarily be shorter however it is that shorter interval which causes the difficulty to rise. Yes for a short time the time between blocks can be <10 minutes (and in a falling hashpower environment it can be>10 minutes) however the network readjusts difficulty every 2016 blocks. Hashpower can't keep growing at 20%+ per adjustment forever and when it slows the time between blocks will normalize at ~10 minutes regardless of if we have 1 MH/s or 1,000,0000 PH/s. |

The small slot at the front is to accommodate one 5V and multiple 12V power connections from the external PSU as well as the RJ45 for Ethernet and a USB They changed it, apparently (didn't see the initial news). Thanks. I wonder what the 5VDC input is for? I would imagine the bulk of the load is going to be on the 12VDC rails (which make sense) so it is now just more of a curiosity. |

Anyone send an email for clarification instead of speculating on the speculation?
I'd do it myself but I'd prefer someone that is more knowledgeable about electrical engineering to write it up.
Not sure the best email but it is a relatively simple question. Just send this (or link to the thread): The news released today ( https://www.kncminer.com/news/news-28) provides some details on the case. Included in the update was the statement, " The small slot at the front is to accommodate the multiple 5V power connections from the external PSU". The use of 5VDC is unusual given the power requirements of the units. A PSU capable of high amperage at 5V is almost certainly going to be more expensive and/or less efficient than an ATX PSU capable of the same wattage at 12VDC. Can you confirm the input voltage is indeed 5VDC? If this is a typo can you provide a fix at the link above? |
