182  Bitcoin / Hardware / Re: Visit of ASICMINER's Immersion Cooling Mining Facility on: November 26, 2013, 01:29:07 AM
So much for being a "secret mining location" when you posted photos of easily identifiable buildings surrounding the area.

I identified the location: http://goo.gl/maps/85lpj

It wasn't very hard. It turns out the building with green/blue tiles is where Allied Control's offices are located (Global Trade Centre, Units 305-307, 3/F, 15 Wing Kin Road, Kwai Chung, N.T., Hong Kong). Which makes sense since Asicminer is likely one of their first and/or biggest customer using their latest immersion cooling platform.

Note that Asicminer owns and operates multiple locations, and this one probably represents a small portion of their mining operations.

184  Bitcoin / Press / 2013-11-21 The Atlantic: Bitcoin Is the Segway of Currency on: November 21, 2013, 09:22:47 PM
http://www.theatlantic.com/business/archive/2013/11/bitcoin-is-the-segway-of-currency/281625/

Generally a negative and misinformed article.
- author is unaware of rapid adoption of Bitcoin by merchants (BitPay's 10,000 merchants...)
- author incorrectly uses term "ponzi scheme" (applies it to gold as well)
- author doesn't realize irreversible transactions are something merchants *want*
- author is unaware of many practical benefits of bitcoin (people escaping their country's inflationary currencies, sending money abroad with lower fees, etc)

Quote
Now, for those of you who aren't techno-libertarians, Bitcoin is supposed to be a virtual currency you can use to buy things online. Except it's not really a currency, and you can't really buy that much with it. It's more like a dotcom stock—circa 1999. See, in just the last month, one bitcoin has gone from closing at a then-record $192 to reaching $788 on Monday. It then opened at $502 on Tuesday, before briefly rocketing up to $900, and ultimately falling to $646. Just your average 80 percent price swing. That's totally normal for currencies ... if you multiply their biggest swings by 80.

[...]

See, the idea behind Bitcoin is to create a decentralized currency that central banks can't inflate and governments can't tax. Basically, digital gold. And like actual gold, the only way to get new bitcoins is to "mine" for them. That involves running a computationally-taxing program on your computer that mostly generates gibberish, but maybe, just maybe, some bitcoins too. The key, though, is that mining for more of the virtual currency doesn't create more of it. That's because there's a predetermined number of bitcoins. Specifically, there are around 12 million today, and there will be 21 million in 2040—and no more after that. Of course, this limited supply means Bitcoin should tend to increase in value against the dollar. But only tend to. See, its deflationary bias means Bitcoin prices will go up and down quite violently. Think about it this way. The supply of bitcoins can't increase much to meet increased demand, so increased demand will make prices soar. And soaring prices will make early adopters try to cash out their winnings—which will send prices crashing back down.

In other words, Bitcoin is a Ponzi scheme libertarians use to make money off each other—because gold wasn't enough of one for them.

[...]

There are companies trying to expand Bitcoin beyond its core constituencies of libertarians, gamblers, and people buying drugs. The startup Bitpay, for one, lets merchants immediately convert any bitcoin payments into dollars. The idea is it can charge lower fees without making companies take on the risk that Bitcoin's value falls. It's a clever idea that should make merchants more willing to accept bitcoins ... but won't make people more willing to use them. The people who have bitcoins still have no reason to spend them, and the people who don't still have no reason to get them. They don't want a currency whose value you can't predict from one hour to the next. They don't want to buy things anonymously. And they don't want transactions to be irreversible (and certainly wouldn't want that if they got hacked).

Every big idea starts out sounding crazy. But not every crazy-sounding idea ends up being big. History is littered with Segways. But for all its majestic dweebiness, at least the Segway was kind of useful. You really could zoom across sidewalks without anything resembling effort. I don't know why you'd want to, but you could. But what can you do with Bitcoin? Well, it's good for real and fake gambling. Since it doesn't have any actual fundamentals, it can be worth anything: Bitcoin 36,000 and 36 are about equally plausible. That's good for making money at the expense of people who get in the game later, but little else.

So the biggest difference between Segway and Bitcoin might be that even mall cops won't use Bitcoin.

185  Bitcoin / Press / Re: 2013-11-15 - Make a Fortune with ASRock's Latest Mining Machines: H81 Pro BTC & on: November 16, 2013, 12:53:25 AM
BitcoinBlogger has written a nice technical analysis of why the product is a dead-end marketing gimmick not just for Monarchs but also GPU altcoins.

Quote
The danger to GPU miners comes from use of graphics cards that only require 2 x 6 pin PCI-e connectors from the power supply.  The 2 x 6 pin PCI-e connectors only provide a maximum of 200W from the PSU, leaving the rest to be provided by the motherboard.  Cards such as certain models of the HD 7950, only require 2 x 6 pin PCI-e connectors but could potentially pull up to 225W total, leaving 25W to be provided by the motherboard.  If the card is connected to a PCI-e 16x lane with 75W available throughput, then there is no problem; however, if the card is connected by an unpowered PCI-e x1 riser to a PCI-e 1x lane [max throughput of 10W] melting occurs.  ASRock has done a good job making sure that the damage won’t be at the 20+4 pin ATX connector, but the physical risers that must be used, and the soldered PCI-e 1x lanes would all be susceptible to damage.

ASRock has provided the changes to the motherboard hardware necessary to provide as much power to the motherboard as is needed to power 6 GPUs; however, the use of PCI-e 1x lanes again necessitates the use of powered PCI-e risers, which negates the ASRock H81 Pro BTC’s only advantage.  Given the fact that the H81 Pro BTC only has 1 PCI-e 16x lane and 5 PCI-e x1 lanes, users will still run into significant power issues the majority of the time if they try to take advantage of all the motherboard tries to offer for GPU mining.

The Butterfly Monarch (BFL) PCI-e card, scheduled for 2014 delivery, would also be a poor match for this motherboard.  Even assuming that BFL makes their target power consumption of 350W it would be impossible to get 6 Monarchs on one motherboard without having two prohibitively expensive power supplies as well as the necessity for powered risers.  There are dozens of better motherboards [better in this instance means PCI-e 16x lanes instead of PCI-e 1x lanes] for mining.

http://bitcoinblogger.com/asrock-releases-bitcoin-mining-motherboard-1-year-late/


This bitcoinblogger post is COMPLETELY wrong that "the use of PCI-e 1x lanes again necessitates the use of powered PCI-e risers". There is absolutely zero improvements to power supply that a PCIe x16 connector would bring to a PCIe x1 connector. Both have 5 lines providing +12V (B1-B3, A2-A3). Both PCIe x16 and x1 have the same current capacity. Both can melt if too much amps are drawn. I say this as the person who first documented to this community the ability to down-plug x16 cards into x1 slots.

I see avalon chips that are cheaper then 10$

Probably Avalon 110nm. We are talking about 55nm chips here.

12BTC for a reel of 500. At $350/BTC, that's $8.40 per chip.

My bad. I didn't see the recent price decrease for a reel (was selling for 30 BTC).

I guess some people prefer the fact they are self-contained, do not require teh paper-clip trick, etc.

Anyway, I sold them. Thanks all!

Create a blade which can be used to replace a current one in an avalon and sell it at a price which leaves a 20-30% earning margin to the buyer and you can probably sell six thousands of such blades in a few hours...

That's the impossible part. Everybody has a different idea of what the price should be to "leave 20-30% earning margin". And if you want to satisfy most potential buyers, the price has to be such that the vendor has to sell at loss.

Look: a Avalon 55nm chip at 1.5Gh/s delivered about 2 weeks from today would probably not mine more than 0.060-0.070 BTC during its entire lifetime (most people would agree). If you want to leave 20-30% earning margin, it means the vendor would have to sell at less than 0.046-0.058 BTC per chip. But the chip alone costs 0.060 BTC from Bitsyncom...

197  Bitcoin / Hardware / Re: Damaged 10 chip Avalon board need help making an interface to test the board on: November 02, 2013, 12:04:52 AM
I would connect this to a PIC16LF1459 using the open source circuit from BkkCoins  Klondike design.
This wound not be the easiest way but it would be fun especially if you had 2 modules to connect.

Yes. If you prefer the DIY route, this would be a fun project.
198  Bitcoin / Hardware / Re: Damaged 10 chip Avalon board need help making an interface to test the board on: November 01, 2013, 11:08:29 PM
I see you bought one of TAV's hash units —the red PCB is a giveaway Smiley

The easiest would be to buy a control unit, pdu (see these boards at https://en.bitcoin.it/wiki/Avalon), and a hash panel (those long PCBs with 8 headers to plug in up to 8 boards). TAV can sell you these boards, contact info@thinairventures.com
