Even in the event that an attacker gains more than 50% of the network's
computational power, only transactions sent by the attacker could be
reversed or double-spent. The network would not be destroyed.

Flipped Jally back to shipping.. it really looks like they are trying. I hope they keep it up.

Can you explain how your hash rate estimation differs from the Coinish.com calculator? I punched in some numbers for the KnC Jupiter and depending on delivery date and scarily enough, didn't even break even. I threw in the 10% fee to approximate hosting + pool fee: http://imgur.com/p5YrFkYI suspect the 1.3% difficulty increase per day may not be sustainable? |

Something is wrong with coinish.com calculator. My spreadsheet shows 180BTC in 6 months, if delivered in october, with 1.3 incrase per day. After that 6 months it will earn only 15BTC more. Try https://bitclockers.com/calc. It's using monthy increse, so instead 1.3% you put in 47%. Have to do two calculations: first to find out what's the difficulty going to be in october, then another using just calculated difficulty as starting point. |

I think ujka is right, other people on reddit and such have been mentioning this too. It's possible that the people at coinish are estimating their numbers on data given by chip manufacturers. Often these estimates are extremely high compared to what realistically will occur. If KnCMiner delivers on time it'll be a first in the ASIC game  It is possible that they will be right, I used to have up to 26% on the table. Not because I think it could reasonably stay that high for a year, but because it looks like we could have a huge surge in the beginning of the year, which could make 13% come out looking about like 26% would. What is really not sustainable is a huge increase in difficulty over an extended period. Difficulty tends to surge and plateau. |

I followed your suggestion and ran the 47% per month scenario based on the current end of June difficulty... http://imgur.com/isSFMUhThat results in BTC188 at the end of 13 months if you start mining in October of this year, if my numbers are right. This makes me feel better about the investment. Hopefully KnC will continue to under-promise and over-deliver : ) |

I increased the spread back up to 25% to show what happens if the difficulty does go higher.

You should ony lists the Actual Manufacturer of the Asic Chips, and they are only a few, Bfly, Avalon, Asic Miner, KNCMiner and Bitfury, all the rests are only buying the chips from these guys and assemble.

But the costs differ by assembler and you have to factor that in for ROI, right?

Shipping, customs tariffs, PSU size and efficiency, overclocking, cooling / heat sinks, electricity costs, downtime, etc etc etc...
Lots more that is not in the table but at least it shows you that Klondikes, although using 110nm, are one the better options if you can get a sufficient number of them, and what is not on there are cooperatives building at COST for members. I suspect any other open source Gen2 chip will also be a great value if it is sub 55nm. One should carefully measure which option is best for you but given the flexibility of the DIY products that is where I would be going. Burin, Alten, BKKCoins, mrb, bitmine.ch etc.

Yes, it's unfortunate that the table can't encompass every bit of info. I am working on making multiple tables, though, that give a more full impression. Doing things like having 3 different ways of calculating difficulty and comparing them, adding likely costs of the DIY manufacturers that they haven't.. a lot of information like that. Also I can make custom tables to take a person's electricity cost and shipping into account.

I'd be very interested to see those charts! Thanks for the effort you put toward making and maintaining them! |

Updated a couple numbers. I thought it would make the table look better, but unfortunately there is more red and yellow, with ever shrinking green.
I thought by now Avalon would have gotten chips out. Maybe I'll split the chart, like has been talked about in this thread.

Is it possible to put a dropdown select-menu on the month field?

That's a good idea. I'm about to rework the page, was actually thinking about doing that.
I'm going to give each manufacturer their own page and each machine it's own table showing the effect of different time periods. So we don't really need the drop down menu, but I still think it would be great to have on the main page. That, or fields you can type your own information into.

Oh strange, guess they didn't do an email alert? Thanks for letting me know, I'll put this in right away. [done] |
