3361  Bitcoin / Hardware / Re: CoinTerra announces <$3/GH January pricing and new product availability on: September 13, 2013, 04:07:32 PM
WTF...the price is less than half the December batch?  You guys had better ship all those December orders on December 1st or there are going to be some seriously pissed off people. 

+1!
I have ordered 5x2TH/s for $70.000
And now I get get 10x2TH/s for the same, but I must
need to wait one month more?

Thats really not fair! I will try to upgrade my order to 10x2TH/s

How can you spend $70K on something you dont even seem to grasp the basics off?
Here is a hint:
https://bitcointalk.org/index.php?topic=283820.0

Now put in 8PH/s (10+ PH if you actually believe CT will ship in december) in your calculator and see what happens.
Hint: not much good, and it will only get worse. If you think current ~80%+ network growth per month is terrifying, you havent seen anything yet.

Nothing weird about that old domain name being unused now, is it?
BTW, Id change my company name too if it was called CeBaTech.

So I just ordered a BCC via bitmit, but its useless because the site doesnt have the bcc function anymore?

I opened a ticket for that too, and they blamed a website mistake thats supposedly fixed. Dont know if it is, but you can do what I did; look up the SEPA address that corresponds to that card. Use that as withdraw address, see the documentation of the card.
Mine starts with PL20. Works fine that way, and the visa card is credited instantly when the withdrawl is processed (once per day), so they use the same bank I guess.

This is the crypto standard that the NSA sabotaged: http://boingboing.net/2013/09/11/this-the-the-crypto-standard-t.html

Or that's the one they dont care about if you know it, since apparently its used pretty much nowhere.
I also dont see how that would fit in to this quote from the guardian article:
Quote

An internal agency memo noted that among British analysts shown a presentation on the NSA's progress: "Those not already briefed were gobsmacked!"

The breakthrough, which was not described in detail in the documents, meant the intelligence agencies were able to monitor "large amounts" of data flowing through the world's fibre-optic cables and break its encryption, despite assurances from internet company executives that this data was beyond the reach of government.
http://www.theguardian.com/world/2013/sep/05/nsa-gchq-encryption-codes-security

I dont think anyone would be gobsmacked if they found out an obscure, slow, suspect, almost never used psuedo random generator was hacked.

I dont know what to trust anymore right now, but on the top of things I no longer trust, is Tor;
http://news.softpedia.com/news/The-US-Government-Funds-60-Percent-of-the-Tor-Project-381195.shtml

Is that what they cracked in 2010? Who knows.But I doubt they would fund 60% of a project which sole goal is precisely to make it virtually impossible for NSA and others to snoop on its users, unless there was a tangible benefit to it.

Anandtech did.
But seriously, check the VPs linkedin page. He is also founder of a company called solid oak technologies, and referenced by that companies linkedin page:

And their website links to that same linkedin page.
Solid Oak is not a huge multinational, but it does exist has been around for a few years, even made it to eda digests's "top 20 companies to watch" last year:

3369  Bitcoin / Mining speculation / Re: Bitcoin: On our way to a Petahash on: September 13, 2013, 12:08:21 PM
Actually we're heading towards a exahash.

Reasoning: those upcoming  28nm chips produce ~500GH and my guess is ~$30 is roughly the price at which they can still be sold profitably (that includes basic PCB,  housing, minimal markup; variable cost of the chip alone is probably closer to $10 in large volume). So as long as there is demand at or above that price point, it makes sense for asic vendors to sell (or produce and mine themselves). If you do the math at what point most miners would no longer be interested in buying 500GH (250W) for ~$30, depending on electricity cost and BTC exchange rate, I get at a difficulty on the order of ~100 - 200,000,000,000. Which means a network speed of roughly a exahash. Thats where we are headed IMO, though Im not taking any bets how long it will take. Could be as little as 2 years from now  to get close to that.


Excellent reasoning. I think you are on target. It would be very interesting to get a leak on how much chips actually cost at manufacturing (28nm for example) to get a base seed value for your estimate.



Im basing my guestimate on the embedded SoC market. A typical highend phone SoC sells for about $15 in large volumes. That is when you buy them from nVidia (qualcomm, samsung etc)., so these companies already have a margin on that, fabbing cost will be lower. OTOH  28nm mining chips may be a fair bit larger than mobile phone SoCs, I dont have any size data (does anyone?), but they should also be a lot more simple to produce and validate, contain less layers, far less IO pins, etc.

My guesstimate may well be off by a factor 2 or 3, but not likely more than that, and so should still give you a ballpark idea.

3371  Bitcoin / Mining speculation / Re: Difficulty curve on: September 13, 2013, 10:19:57 AM
It's an exponential right now, but in a few months this curve will look much more like an 'S' curve.

The question is when will it start to tail off?

My guess is December, what does everyone else think?

Most certainly not december, December and January are the months you will probably see the biggest difficulty explosion ever, assuming at least some of the promised 28nm products make it to the market roughly on time.

When is it going to taper off? When marginal production cost meets mining profitability. Until then, ASIC manufacturers will just drop prices to maintain sales (causing difficulty to increase further, and requiring further price drops).
Cointerra is now on preorder for ~$2800 per chip. Im guessing variable production cost of the chip alone is closer to $10 per chip. Do the math were difficulty would need to be for 500GH at ~$10 (+PCB+ case+margin, say $25-$30 ) to be only marginally profitable. That gives you an idea. Then double it when 20nm becomes affordable.  The short answer is: not anytime soon.

edit; pallpark figure, when difficulty reaches ~100,000,000,000 is where 500GH for $30 is only marginally profitable, depending on electricity cost, BTC rate etc,  Take that figure with a grain of salt, but it gives you an idea. It may also taper off sooner, but OTOH I also expect we will overshoot this value due to inertia, free electricity and miner myopia.  Also, this is a race, until we get close to this point, the only brake on network growth will be the ability of the various vendors to produce and ship. Unless they are all as inept as BFL and avalon in getting their goods out of the door, that may go incredibly fast. If you thought 2013 was crazy, you havent seen anything yet.
3372  Bitcoin / Mining speculation / Re: Estimate of ASIC pre-orders (6,000 to 8,000 TH/s by end of 2013) on: September 13, 2013, 09:20:14 AM
these seem to be missing:

http://virtualminingcorp.com/
No idea of volume, but they sell seriously large machines (up to 25TH) and  they claim "Shipping Starts October/November 2013"
If they can get even close to that, its probably reasonable to assume they will have ordered a significant number of wafers (they would be crazy not to) and they may even challenge Cointerra for volume.

Note fast-hash=!hashfast

Also missing afaict:
https://www.xcrowd.co.uk/
again, no idea of volume, Im guessing no where near the other big players, as it seems too little too late, but shipping supposedly starts this year
"Bulk shipping start date - 20-12-2013 200 or 20% of total orders to be shipped per week"

One last remark; the exact timing of the global hashrate increase is of little importance for those not mining yet or not mining very soon. If all those 28nm asics end up being a few months later than projected, it means customers (on average) will receive them that much later, but also that the associated difficulty increase will be delayed. In the end its a wash on average. Obviously what does matter greatly is difference in shipping dates and execution between companies, but its pretty much impossible to guess who will meet their goals and who wont (and by how much they miss it). May as well assume promised delivery date, or apply the same delay to everyone.

Yeah, sounds fishy to me too. No mention of the bug either though I clearly witnessed it and I had a few 1000 euro extra balance that I shouldnt have had. Which means someone else or btc-24 is missing that. Last time I checked they werent a central bank.

NOt only is it down, they had a huge problem with their trading engine. I was playing with a handful of BTC and somehow making crazy profits. Turned out several orders were executed multiple times and before I knew it I had thousands of euro in trading profit.  I dont know if others managed to withdraw their coins (or money) but if they did, I fear bitcoin-24 may be bankrupt.

This needs to be dealt with by going to the police - not by share-holder motions on a company that has no legal existence.

Of the two Avalons, one was paid for by a loan to the company - which still hasn't been discharged in full.  So from ANY perspective the shareholders do not have clear title to that even if it were accepted that the "company" was a legal person.

There's 0% chance Yifu will intervene.  He'd expose himself and his company to risk for no benefit and set a precedent whereby he'd end up inundated with people claiming Avalon X was paid for with their money so should be sent to them.  He refused to intervene in one such dispute over a loan before.

But if you DO go ahead with this, you could also consider sending a letter to BFL (no translation neeed) and see if they'll do anything about the preordered hardware for usagi's company BMF which has still not accounted for for all the hardware it claimed to have before GLBSE closed.  That company also deleted all posts, won't respond (thread is locked), won't provide updated information, refuses to pay out funds to shareholders and has made promises (repaying all NYAN.A investors in full) that the rise in BTC price has made unlikely ever to be fulfilled.

Rather than attemtion-whoring here with dodgy proposals (you're asking Yifu to break a contract made with Ian Bakewell - without a court order he CAN'T legally confiscate the Avalons), usagi would be better served spending the time finally sorting out the finances of his own companies which have languished without attention since January.  Yes - we GET that you want to list them so you can buy the shares back for cheap by forcing investors into submission by never doing anything, failing to update accounts and withholding their money.  Whining about Bakewell not paying his investors/honouring his promises is the ultimate in hypocrisy as you're doing precisely the same to your own ones.  Or is there somewhere a schedule of how/when you'll meet your promise to refund NYAN.A investors in full?

The voice of reason. +10.
