So as an example:
You buy a Babyjet for 50 BTC, 90 days after delivery the theoretical mining revenue based on difficulty over the prior 90 days and 400 GH/s hashrate rate:
10.0 to 12.4 BTC = you would receive 4 MPP boards as compensation. If 1 board produces 10 BTC then 5 boards (4+1) would produce >=50 BTC.
12.5 to 16.5 BTC = you would receive 3 MPP boards as compensation. IF 1 board produces 12.5 BTC then 4 boards (3+1) would produce >= 50 BTC.
16.6 to 24.9 BTC = you would receive 2 MPP boards as compensation. IF 1 board produces 12.5 BTC then 3 boards (2+1) would produce >= 50 BTC.
25.0 to 49.9 BTC = you would receive 1 MPP boards as compensation. IF 1 board produces 25.0 BTC then 2 boards (1+1) would produce >= 50 BTC.
But the key point is the MPP delivers the goods 3-4 months after the miner. A reasonable assumption will be the 400 GH/s will reach at least 50% output, with the MPP providing 1 board 3-4 months later. Since difficulty is skyrocketing, that 400 GH/s MPP board is actually only worth about 50 GH/s. MPP will not provide positive ROI because it provides the hashrate too late. MPP is nothing more than roi theater. |

Several of you have asked this, or suggested that it is not my business. My answer is that the size of the money supply is everyones business.
Do you own my bitcoins or do I? What I do with my bitcoins is none of your business. If I want to have them sit untouched in a cold wallet for 40 years until my grandkids are old enough to manage them theirselves, then that's what I'll do and I'll fight you trying to steal them from me till the day I die. |

The only cost might be UPS were already paid and you'd lose $120 on throwing that label in the dustbin.
A label is fully refundable up until the time the UPS driver scans the package. There is no excuse for not offering full refunds as promised up until the time the package is picked up. |

8. The power consumption of the device.
Anyone know why the power consumption is so much higher than other BitFury-based miners? |

I think it could be helpful to remove some of the uncertainty around old coins, to see if they are truly lost or not.

11 days and counting on an 8.5K USD withdrawl
USD withdraws aren't going out right now. Can anyone confirm a regular USD withdrawl to the US in the past 4 months (that wasn't using the 5% special fee)? |

1) There are no more refunds.
Not necessarily: Refunds are offered up to the day of shipment of your order.

How much is a 50 GH/s BFL Bitcoin miner worth if it starts mining
at the 20. of October 2013.
Normally the difficulty is increased every 2016 blocks. Which is
about 14 days.
Szenaria with Current Difficulty Increase
The difficulty increase is calculated with 30% over each time
frame. This is the current increase per time frame.
The difficulty always adjusts at exactly 2016 blocks. If you are estimating 30% difficulty increases, then those 2016 blocks will take about 11 days, not 14. |

The chip is specified as 1 GH/s @ 2.05 W with 128 Hash units on the chip.
This chip is DOA. There are already better chips available today. Why wait months for an inferior chip from a supplier with a horrible track record? |

Wouldn't it be more likely that the owner made a human mistake and got caught somehow?
From reddit: It looks like they sniffed him out by looking back at old Internet records (forum posts, IPs etc) from around the time of SRs appearance. The first person to ever advertise SR was DPR himself, and he used an email account attached to his natural born identity. No NSA or technical hack.
Ouch. What a way to trip up. Next up, finding Satoshi.  |

I still prefer TURDHASH becuse they never produced SH*T.
Now you're insulting turds. At least turds can be used for fertilizer. |

Mining testnet is a very similar workload to mining shares on a pool. If you were saying you wanted to see a solved high difficulty block— that would be another matter. A technically superior test would be to mine recently completed mainnet blocks to verify that the device would actually submit solutions. As it'll be quite awesome when, intentionally or otherwise, some mining asic has a "bug" that causes it to lose some percentage of its full solutions but not its shares... widespread deployment of such a device would probably put every pool out of business in a few days.  [Aside: I'm only bothering to reply to this thread because it's currently on top] Then let's keep it on top! "very similar". See, "very similar" isn't good enough for me. I have a lot of money invested in my miners. Do you ship new versions of Bitcoin without running them on the live network? Until there is a test suite that verifies the protocol completely, there are all sorts of issues that could crop up on main net that don't show up on test net. Test net is a good starting place, but it doesn't offer everything that main net does. |

I would not buy a miner that hadn't proven itself mining on the real net. Testnet is not the same.

While I was perusing the site looking at different models, the "Can we help you?" chat window popped up and I had a good discussion with Jim. The conversation was enough to diminish some of my fear, and Paypal buyer protection gives me some other measure of hope, so I placed the order.
As long as you stay inside the 45 day window you'll be fine. |

This is from their twitter 4 hrs ago:
KNC Miner @kncminer 4h
Jupiter speed now at 596
And this is from the actual mining: 3 hours 474.37 Gh/s

I invest in things based on as many factors as I can put in, for the express purpose of making a profit. That's like saying that a stock dividend in Euros is invalid because it's not in dollars. Money is what again?
A medium of exchange.
His math was fine. It was his axiom I was questioning.
Bitcoin mining hardware creates bitcoins. Bitcoins-in vs. bitcoins-out is the most logical way to evaluate an investment in mining hardware. |

Kudos to KnC for building the first 28nm Bitcoin ASIC! |
