Considering they'll make over $100 each in the next seven days we will accept no bids under $700 each. Otherwise we're much better off running them into the ground. Yes difficulty rises are getting much larger but if you look at the last ninety days difficulty increase ratios are getting smaller. Just like 200% rise of 50 is 100 and a 100% rise of 100 is 200. So even the jump in the example was much bigger to 200 the rate of change is slowing. You should factor that into to your profit calculations on them. Plus bitcoin prices are rising and we accept USD and GBP bank transfers.
(just because I hate "rough estimates" without supporting math -- as of 10th Oct, 2013) 5.4 days till diff adjustment. Round down to 5 days since we've seen spikes well over 2PH numerous times in the last week/two. $167.71 USD according to "bitaverage" Daily production for a single 54-62GH single is approximately 0.1 btc a day, or 0.5 btc between now and then. Once diff adjustment hits, daily output drops to 0.08 btc day, so you'll rack up another .16 btc, for a total of about .66 btc over the next 7 days, or $110.69 assuming price stays static. Next diff jump will coming another 10 days later so you'll earn another 0.8 BTC, for a grand total of 1.46 BTC, or $244.86 over the next 17 days. The next diff jump beyond that one will likely drop your earnings into the 0.06 btc day / $11.26 day range. Quick math says that if you had the box, in your hands today, you'd make --about-- 1.46 + 0.72 btc, or 2.18 BTC over the next 30 days, or $365. The diff jumps AFTER those start getting into CRAZY Cointerra/BitFury/etc/etc shipping, and your single will make you less than $100 a month quite quickly. And your ROI's get MUCH worse if the price drops back down into the $120 range where it was a short time ago. My Point to all this? A BFL single @54-62GH isn't worth $700 today.. It's worth about $300, and $200 next week. Because VERY VERY soon, Cointerra/others hardware, shipping in the $3-5/GH range will be in peoples hands.. and that's what you're trying to compete with when you're selling yours. |

That's a good point, but bear in mind I'm being paid professional rates from the other manufacturers in the still-in-design phase who will then be supplying me with prototypes and finally real hardware which really puts to shame the "offer hardware and code after the fact" approach.
\em crossing fingers that's Cointerra. |

^^ perfect, thanks.. will go fix all my scripts.. Might want to update miner.php while you're at it to work with the API changes.

Luke-Jr:
Any reason why the extended-core information for BFL's (seeing all cores per Single, for example) went away from 3.2.90 to 3.3.0 via the API?
I used to get all 16 cores per single, now I see only summary information.

Just updated to windows 8.1 and my BFL SC Jalepeno would no longer work.
Heads up for anyone else having issues, the problem is not with cgminer but the USB driver. You just need to open zadig again and apply the WinUSB driver.

USB problems? Buy a $40 raspberry Pi, grab one of the mining-pre-loaded distros like MiningPeon -- http://minepeon.com/index.php/Main_Page PiMiner -- http://learn.adafruit.com/piminer-raspberry-pi-bitcoin-miner/And don't worry about windows broken-ness any more... totally worth it. |

2 @ 5btc each, shipped overnight to Portland, OR, USA .. insured, escrow
Strong offer.. last diff jump was brutal, next will be just as bad thanks to KNC.. I'd offer 3 each.. so 15 BTC for all 5, prefer using bitmit for escrow service. |

Yay windows. At this rate I'll ... completely deprecate windows support  ... actually expected that ages ago ... |

absolutely beautiful work.. well done.

Think about it. This shipment has been the most disruptive major volume of hashrate unleashed upon the network in a short period of time. You're seeing the effect of that. KnC aren't shipping for another month. Who else is going to have such a marked effect in that time? When they do ship on the following occasion it's unlikely to be equal to what's shipping now, and even if it was it wouldn't have the effect the current outlay will, because the current shipment will already be part of the total network hashrate at that point. They will not be shipping anything like what they are shipping now PLUS what already existed. Therefore the increase will not be as proportional and be more incremental. What you are seeing now will be the largest single increase - proportionately - for a given finite period.
This is nothing... wait till Cointerra start shipping... blooood everywhere... |

love the design, very clean, well thought out... /tip hat
doing quick math, that works out to about 4.5 btc + cooler for each 30GH board, right? Not counting cooler that's rougly a 4 month ROI, and that ROI is about to get much worse in Dec (8/mo) and Jan (11/mo).
I wish I'd had the option to buy this in August...

Anyone looking at ROI's shouldn't even go 5 btc after the massive diff increase today, and the recent price hike. Even turning down tgb's crazy diff estimates to 50% per diff period, 5 btc doesn't pay off itself... ever.. http://mining.thegenesisblock.com/a/31899df662I'll offer 3 BTC each, so 12 BTC total, for all 4, until the next diff jump. After that, bid is canceled. Truth is, with Cointerra taking January preorders for $3/GH, each BFL single is really only worth about $180.. I say this sadly, as an existing Single owner... |

pre-emptive donation sent.. looking forward to flashing my singles when the JTAG hardware shows up. Well done.. you've done a lot of the things I'd been thinking about, but aren't a good enough coder to actually DO.

Payment sent and confirmed, lock and load.
pleasure doing business. |
|
|

No worries, yes it has been a rather interesting day. Deal reached, payment terms pending. Standing by.
Your turn.  |
|
|

Sent you an updated offer, I guess you're away in someplace warm ATM. Sorry, swore I replied to you, but then BTCUSD went crazy, and I think I forgot to hit submit.. You do have PM now however. |
|
|
|
You willing to come down a bit if I purchase all of them?
Absolutely open to offers.. make me one either in PM or here. |
