BFL ASICs ROI gets shaky with a $60 bitcoin at 1,500,000,000 difficulty ... but I guess there's Europeans with 50c per kilowatt/hour power bills.
I think you added a few too many zeros. http://www.coinish.com/calc/#BFL 50GH/s @ $2499 (straight from their product page) will never generate a return @ 80,000,000 difficulty, $94/BTC and 1.2788% growth rate. ASICMiner is looking at this same curve. Very soon it will not make sense for ASICMiner to deploy their own hardware. ACTUALLY: At 640,000,000 difficulty a BFL SC SINGLE will still be making ~ 1.32 btc per month. You're numbers are just plain wrong and ASICMINER about twice as power hungry as bfl gear (and 2/3 as avalon). ~ If you had a SC SINGLE in hand right now - you'd roi in under 2 weeks. @ 80,000,000 difficulty it's still under 3 weeks. Given a device that hashes at 50GH/s for $2499 ( https://products.butterflylabs.com/) The first day at 80,000,000 difficulty, the device generates 0.314321 BTC. Here is the series for bitcoins generated per week for 28 weeks with a 9.4% difficulty adjustment per week starting at 80,000,000 difficulty. 2.2 + 1.99 + 1.81 + 1.64 + 1.48 + 1.34 + 1.22 + 1.10 + 1.00 + .90 + 0.82 + 0.74 + 0.67 + 0.61 + 0.55 + 0.50 + 0.45 + 0.41 + 0.37 + 0.28 + 0.23 + 0.21 + 0.19 + 0.17 + 0.15 = 21.92 ($2126) On the first day of the 28th week the device generates 0.0218 BTC I checked that series with the following calculators and using a spreadsheet. http://www.bitcoinx.com/profit/http://tpbitcalc.appspot.com/http://www.coinish.com/calc/#https://bitclockers.com/calc |

If ASICMiner gains too large a share, they will kill the golden goose. They have no plans to do so. The current ASICMiner equipment is first generation bitcoin ASICs. KNCMiner will be far more efficient and much cheaper. Follow on offerings of third and fourth generation ASICs will be even more efficient and cheaper. ASICMiners current hardware will eventually be as outdated as GPUs are today.  The transition to ASICs is a bumpy one, but so was the transition to GPU mining. |

So they shipped June 2012 orders in April 2013 and they are shipping Sept 2012 orders at end of June early July 2013.
BFL was making up a little ground, but now it seems they are slipping behind again.
How hard is it to call Foxconn or Quanta and say "Make me 50,000 of these"?

Only if you buy 100 and get them tomorrow.
How does the amount purchased affect profitability at all. Makes no sense. D Well it affects the absolute value Losing money on each one but you will make up the profit in volume! A loss is a loss, in this case the magnitude of one is greater than the other... sometimes humor is lost on the internet... kind of like bitcoin dust. Making the Sarcasm font is on my list of things to do. |

Basically the dollar is such a good investment that people are all jumping on board. I cashed out all of my stocks and bought dollars.
I have also taken out a huge loan in the hopes that the dollar goes up a lot.
We are all going to be rich!
that's what they said during the roaring twenties  If they had bought dollars in 1920 it would have been a good investment for 12 years. |

I don't even see the problem. They changed the TOS and people approved it at purchase. Anyone dumb enough to order in the last few weeks without doing their own due diligence deserves whatever happens. Unless they read one of Inaba's quotes that said that people with BFL orders can always get a refund. Also, BFL cannot force Paypal to withhold a refund. |

One of the few BFL threads with actual value.  |

What an incredibly stupid thread!
The OP probably made a fortune off of BFL investors. Now he is quiet while the BFL orders roll in for 10 cents on the dollar. If you are going to scam folks, go after BFL investors. They are pre-screened for you.  And the OP was right about one thing: There is very little chance of BFL being honest enough to refund everybody's orders...

If BFL changed their refund policy, they must have done it within the past week.
They did, that is why it is news. Pretty sure all you have to do is talk negatively about BFL in public and they force you to take a refund.
I don't see what the big deal is. If you want a refund just start a thread and talk some shit.
Genius. |

The 1000 BTC bet was dealt with. Get over it.
Which bet? The one where they did not pay. Or the one where they donated the money to themselves? Don't worry, if you don't like BFL just ask for a refund! |

2000 BTC invested in a BFL pre-order 1 year ago now generates 13 BTC a day! Wow!!! This *might* break even someday.
100 BTC invested in an Avalon pre-order 9 months ago has already made back its investment several times over.
30k USD invested earning 1k per day seems to be an ok deal. Please don't start with but 2000btc is worth so much more now. Everyone can hold as much or as little btc for long term speculation as they like. Having said that no preorder should take a year to ship that's just silly. 1 BTC is worth 1 BTC. Paying 2000 BTC to get less than 2000 BTC is a bad deal. It is amazing that we have to explain to people that having 2000 BTC is better than having less than 2000 BTC. But there are some seriously math challenged folks here. |

"Came through"?! It was supposed to be 1500 GH/s @ 1500 watts in October '12. Now it's 500 GH/s at 2400 watts in June '13. They didn't "come through". They blew it.
A) They will be compensating customers with 3x the number of units, so you will be getting the same hashrate as what you paid for. B) Lets see you do any better. 2000 BTC invested in a BFL pre-order 1 year ago now generates 13 BTC a day! Wow!!! This *might* break even someday. 100 BTC invested in an Avalon pre-order 9 months ago has already made back its investment several times over. 30k USD invested earning 1k per day seems to be an ok deal.

Having said that no preorder should take a year to ship that's just silly. You should never judge the return on capital of a piece of mining equipment by the USD exchange rate. You should just use BTC in vs BTC out. Don't buy equipment that is going to give you less BTC than you can get just buying BTC instead of the equipment. Operating costs of course need to do the conversion to local currency for USD, but those are a very small component at the moment. |

You guys know you can't just use a 6 hour windows to estimate hashrate, right? Right?!
Of course you can. You can use a 6 second window to estimate hash rate. It just won't be very accurate. |

Hiya all, I am hosting 10 of these little things for a friend, Problem is he bought when at 2 coins a piece, Using Fiat for the trade and wanted in on the BTC way of life, Now comes the price drop, Meaning he has lost half his investment in a few days  So he asked me weather he should cash out and get 10 coins and sit on them or keep mining? I was a little stumped so I thought I would throw it out there for you guys, I said if you cash out you have paid double price for your coins, If you mine a few coins over the coming weeks and BTC shoots up, You will have made back the investment, Also If you sell for 10 coins and price rises you would have made. Can anyone advise or have a different way of looking at this? The best chance he has to recoup some of his losses is to take delivery and try to sell them on Ebay. |
