Im not sure what Im missing. At $1 per GH, 40K chips x  650GH per chip = $26M, so that chip inventory alone is worth at least $20M (assuming they are chips, not dies).
Just as importantly, there is the maskset and IP that allows a nearly unlimited number of chips to be produced, almost certainly for a cost that is below $100 per chip in volume (my actual estimate is $35), and a market value that of course will drop, but is still >$500 today and will remain well above $100 for quite some time.

Im just a bystander, but chapter 11 makes most sense to me. Perhaps with a forced change of management, but clearly there is potential to turn this around.

no it is a good thing, calling it a myth doesn't make it a myth
what you describe, you can actually get from BFL if you wish
sensible miners reinvest, otherwise you fall behind and end up with almost valueless hardware (or shares in this case)

YOu clearly have not thought this through. Reinvestement is not different from a regular investment, the only difference is the source of the funds. If reinvesting makes sense than so does investing. But guess what, its not always smart to invest in mining, and certainly it will not always be, and most certainly not at price points and conditions you have no control over. What hardware will cryptx buy, at what price and when? You have no idea, you are just guessing he makes the smart move (and doesnt pocket the kickbacks).

its the number 1 mistake amateur miners make, they expect the returns to just make themselves by cashing out weekly and running their rig indefinitely or until the electricity costs become prohibitive.

If cashing out weekly does not recover your initial investment and running costs, plunging in more money will not make it better, it will make it worse. The only difference is that the "amateur" may be able to recoup at least a part of his original investment while the professional idiots who throw all their revenue back in to mining gear time and again, no matter what the market conditions are, may well ultimately be left with basically nothing from their original investment. You are making the gamble bigger, but you are not changing the odds. If you dont grasp this concept, try your reinvesment strategy on Satoshi Dice, let me know how it works out.

your forgetting how much reinvestment benefit shareholders

Time to bust a myth; reinvestment is not a good thing for investors, its a very bad thing. It does little more than locking in future revenue for additional purchases that may or may not make sense at that time. If you were paid out all profits in dividends, you would be free to determine at any future point if it makes financial sense to purchase more, newly issued shares and at what price. Being robbed of that choice is a liability, not an asset. You seem to assume that any expansion at any price and any point in the future is automatically a good investment.

. A post in a forum or verbal statements from a customer service rep does not equal a contract.  

IANAL, but the above Im pretty sure is completely incorrect. Even oral contracts are usually enforceable:
http://blogs.findlaw.com/law_and_life/2011/10/are-oral-contracts-enforceable.html

And in this case, its written down, and not by a random sales rep, but by one of the company's principle officers and cofounder.

It is not Spoondolies vs. AM.
It is Spondoolies against all AM partners out there inundating the market with AM hardware.

Actually, most asic vendor are also selling bare chips.
Cointerra, Spoonsomething, Bitfury, HF Bitmine, ..

They may not focus on it (yet) like AM does, but AM's business model is hardly unique.
1706  Bitcoin / Hardware / Re: HashFast announces specs for new ASIC: 400GH/s on: May 23, 2014, 03:23:38 PM
But the guy was in Canada until a few days ago (the dc should be there and he was meeting with Amy @ Hashfast) and is under investigation by some us federal agency about the unregulated security, so I don't think he will just say "sorry guys, my company is in the middle of the ocean (sorry, I'm not good with geography), you can't touch me". He can't hide for the rest of his long life either, so the law will eventually catch up with him.

Oh, Im pretty sure he already is in trouble over selling unregistered securities to unsophisticated buyers, if nothing else. But whatever deal he struck with HF, I dont quite see what would be illegal about that for him to do. ANd if you are hoping on clawback's from Belize, good luck.
1707  Bitcoin / Hardware / Re: HashFast announces specs for new ASIC: 400GH/s on: May 23, 2014, 03:13:34 PM
The really interesting question is this: Liquidbits made this deal for chips and 25% of revenue being kicked back to Hashfast on March 4th.  But Hashfast defaulted. So who made Hashfast a better offer?

VMC. They are selling both the old HF boards as "Fast-Hash One Prospector", rated at 512GH, and the new yoli evo whatever boards as "Fast-Hash One Gold Rush" rated at 750GH. Its not like they tried very hard to cover that up, just flipping the name lol. Both are reportedly in stock.

VMC is wholly owned by ActiveMining, registered in Belize and run by a very shady person. Their funding comes from  a bitcoin IPO.
1708  Bitcoin / Mining speculation / Re: Hash rate spikes and difficulty analysis on: May 23, 2014, 08:12:12 AM
Actually that spread is smaller than I would have expected intuitively. How did you calculate it? Did you base it on the assumption that on  average a block is found every x minutes (and then applying a poisson distribution), or did you use crunch the numbers calculating for every GH/s the chance of finding a block ? The result might (should?) be the same, but Im a little hesitant to accept that as fact.
1709  Bitcoin / Hardware / Re: CoinTerra announces its first ASIC - Hash-Rate greater than 500 GH/s on: May 14, 2014, 10:25:51 AM
Even with this assumption - $0 electricity/maintenance, 2TH, 24 months, and $12000 one time payment. The difficulty increase has to be at an average of 5% only just to breakeven. Anything higher you will lose money, if you believe going forward we will have average of 5% increase per, i have another bridge in my backyard for you...

Actually, an average of 5% per difficulty adjustment (assuming that is what you meant) for the next two years is extremely unlikely at todays price. That would mean difficulty in two years would be more than 100x higher than today rendering even the most power efficient machines operationally unprofitable for almost anyone. Of course the last ~18 months of that 24 month contract dont really matter, and during the first 6 months it will be well above 5%, so you wont hear me saying this is a sound investment, but on average difficulty adjustment over that period of time will be FAR below 5%, assuming constant BTC price. So how much do you want for that bridge?
1710  Alternate cryptocurrencies / Mining (Altcoins) / Re: Swedish ASIC miner company kncminer.com on: May 14, 2014, 07:08:22 AM
My sources tell me TSMCs 20nm finfet+ process is in such  terrible state that you should expect close to zero devices this year. Everyone and their dog is scrapping 20nm products and/or running from TSMC.

Now Ill grant that a bitcoin asic is by far simpler than a CPU/SoC/GPU,  so if anything can be made to work on their process, it may well be a bitcoin asic, but to say that things go worse than planned would be quite an understatement. So Im not holding my breath.

In other news, lead time for 28nm just increased to 16 weeks:
http://www.kitguru.net/components/anton-shilov/tsmc-extends-28nm-chip-lead-time-to-16-weeks-puts-chip-designers-at-risk/

Thats just TSMC, but Id expect spill over effects to the other fabs just as well.
1711  Bitcoin / Mining speculation / Re: 26 ph up the next 2 days someone testing? on: May 13, 2014, 09:36:13 PM
Tradeblock current hashrate shows 75phs and bitcoinwisdom says 67phs.

What do I miss here?

Their estimates are averaged over a different period. The latter averages over 504 blocks, the former Im guessing over 24 hours.
1712  Bitcoin / Mining speculation / Re: 26 ph up the next 2 days someone testing? on: May 13, 2014, 08:01:29 PM
What are the odds of 90 blocks in 9 hours, assuming 6.6 blocks per hour normally? That turns out to be 0.0000469 (once every 21.2k hours, or once every 887 days).

Using your calculator, its actually 0.013% since you should be looking at the cumulative probability, ie, the chance of hitting 90 blocks or more when 59.4 is expected.
So it would happen more than once per year on average.

But Id also like to see which blocks we are talking about, not sure anyone accounted for the fact that time stamps on these blocks can be wildly off, up to two hours IIRC.

Not a funny feeling no. But Id gladly bet all my coins its AMT posting yet again using alias accounts.

bitcoins dont need insurance if they can show and prove they hold matching bitcoins to cover customer balances.

SO how does that work? Because exchange XYZ can prove it holds all the bitcoins it owes today, that by itself to you is a guarantee they wont lose yours tomorrow? Sounds like you dont understand the difference between an audit and a deposit insurance.
1715  Bitcoin / Mining speculation / Re: 26 ph up the next 2 days someone testing? on: May 11, 2014, 07:52:33 AM
Statistical anomaly?

Obviously. Although I would call it a statistical normality. You are not measuring hashrate, you are measuring the rate at which blocks are found, and we all (should) know thats inherently variable.
1716  Bitcoin / Bitcoin Discussion / Re: Bitpay hyping something BIG on twitter... on: May 11, 2014, 07:46:53 AM
Amazon is already on record that they will not be implementing bitcoin for now:
http://recode.net/2014/04/14/amazon-says-no-to-accepting-bitcoin-maybe-to-building-an-amex-or-visa-competitor/

As for "to the moon"/"big things", Virgin Galactic already accepts bitcoin, so that would be old news.

Im guessing Bitpay is being taken over. Quite possibly by Paypal.
1717  Bitcoin / Mining speculation / Re: The Best Mining Rigs Are Now Barely Profitable -- Now What? on: May 06, 2014, 12:55:09 PM
After some of the earlier conversations in this thread I did a write-up to try to see if I could capture the essence of how this seems to play out: http://hashingit.com/14-prisoners-dilemmas.

Not a bad article, although I dont quite follow you on the conclusion: "Ultimately it is unclear how the mining dilemma can end up having a happy ending for anyone but the energy suppliers". Pretty much all asic suppliers (that dont get sued in to bankruptcy or worse) will have their founders enjoying a happy ending sipping pina colada's on an exotic beach. Thats a happy ending in my book Smiley.
1718  Bitcoin / Mining speculation / Re: The Best Mining Rigs Are Now Barely Profitable -- Now What? on: May 06, 2014, 05:26:00 AM
It's the Bitcoin mining market that is going to crash, not the Bitcoin economy.

How do you define a crash of the mining market? If you mean that hashrate will implode, fat chance Smiley. IF you mean that mining hardware sales will dry up, well, think about the consequence of that. If indeed hardly anyone were to buy miners anymore, the one thing that will surely happen is that prices will plummet, considering most mining asics are still sold at the very least 10x above marginal production cost Clearly vendors would prefer to sell at 5x, 3x, 2x marginal cost over barely selling anything at all.  And if prices plummet, miners will buy again. Its this very mechanism, a spiral of death of exploding difficulty and plummeting prices that caused this, what you call bubble (and what I warned you against if you remember). Its not stopping anytime soon.

"Again you need evidence that lowering voltage to increase efficiency is possible"

 Quod est demonstrandum. Back to ignore.
1720  Economy / Securities / Re: ASICMINER: Entering the Future of ASIC Mining by Inventing It on: May 04, 2014, 04:26:03 PM
Caveat Emptor!  Information asymmetry detected.

ITs not meant as promotion for BFL, Id be the last person to suggest you order anything from there. But the chart is interesting and relevant to earlier discussions about how you can scale power efficiency of every ASIC. Even if you take those numbers with a table spoon of salt, it nicely illustrates my point.  There is about a factor 3x difference in power efficiency depending what voltage/frequency point you pick. That spread is not going to be vastly different for any other bitcoin asic.

 I'm going to pretend it is relevant and probably valid for other ASICs but the fact of the matter is, the price of the devices are set many months before those cute little graphics come out.  Your money has been spent and if the device you spent it on wont make a positive return for you running at the right-hand side of the graph, it certainly wont make money running on the left-hand side.  Ergo,  the plot is meaningless to anyone but the salesman and the scientist.
 Maybe I am missing something.  What do you think your options are now that you have this information?

You're missing the fact there is/was a discussion going about scaling of power efficiency.  For every asic you could draw a similar plot, and power efficiency can be traded for performance per chip. Something obvious to anyone who knows anything thing about asics, but apparently impossible to grasp for jimmothy.  As for pricing, current market prices are so far detached from variable production cost, that for now, this is a moot point. Vendors will charge whatever fools are willing to pay, there is basically no correlation with production costs yet. That will only happen once price per GH has dropped another order of magnitude or so.

As for my "options". The only sensible option is the same one since the very first asic was announced: stay away from them, just invest in bitcoin. Doing that has yielded me 100% BTC denomnated ROI or ~10000% when expressed in dollar. How many miners can say that?
