Bitcoin vault offering insurance is 'world's first'

By Joe Miller
A bitcoinBitcoins stored online have been subject to several raids by hackers

Related Stories

A Bitcoin storage service that insures deposits of the digital currency against loss and theft has launched in London.
Elliptic Vault uses "deep cold storage", where private encrypted keys to bitcoins are stored on offline servers and in a secure location.
The facility's founders say they are the "first in the world" to offer insurance for Bitcoin owners.
Stolen bitcoins cannot be recovered as all transactions are irreversible.

Online wallets used to store bitcoins have been subject to a number of cyber-attacks and some users have also suffered from accidental loss.

James Howells lost about £4.6m when he threw away his hard drive, forgetting that he had bitcoins stored on it.
Unlike money stored in a conventional bank, bitcoins are not insured and there is no way of retrieving them once they are gone.
'Obvious step'
"One of the main concerns people have with Bitcoin is that it's quite difficult to store securely," Elliptic co-founder Tom Robinson told the BBC.
"Offering people insurance seemed an obvious step."
But convincing an insurance firm to trust the nascent currency was not an easy task.
"It was very difficult to find an insurer," said Mr Robinson, an Oxford graduate with a PhD in physics who started the company with two friends.
"The industry is very conservative and they did not understand Bitcoin.
"They were also influenced by the negative publicity Bitcoin received, although this has improved since Silk Road [an online marketplace] was taken down and stopped dominating the Bitcoin agenda."
Layers of security
The company is underwritten by Lloyd's of London, which will give people "more faith in the Bitcoin system", according to Emily Spaven, managing editor of CoinDesk, a digital currency news site.
Insurance payouts will be calculated using the Bitcoin to US dollar exchange rate at the time a claim is made.
Elliptic's focus is on storing bitcoins as securely as possible, using what Mr Robinson calls "deep cold storage" techniques.
Bitcoin keys are encrypted and stored offline. There are multiple copies, protected by layers of cryptographic and physical security.
The copies are accessible only via a quorum of Elliptic's directors.
Illicit financing
Elliptic's launch comes as Bitcoin has been making news around the world, with governments deciding how to legislate for the currency.
Singapore has become one of the first countries to issue guidance on taxation for Bitcoin businesses, although it also said it was monitoring transactions to detect illicit financing by criminals and terrorists.
Bitcoin was less fortunate in China, where the largest online marketplace, Alibaba Group's Taobao, said it would ban virtual currencies.
In December, the country's central bank ordered financial institutions to halt Bitcoin-related services and products.
There was a breakthrough for the currency in the US, however, where Overstock.com became one of the first major online retailers to accept Bitcoin on Thursday.

UnderMining a college campus…



The concept

Everyone has heard of Bitcoins. Whether or not they will grow (personally I hope they do) is irrelevant for this article, because I wanted to try my hand at mining. However, I don’t have a high GPU gaming system, and didn’t want to drop $2-10k on a dedicated GPU miner…. So I was looking in the CPU direction.
Of course, anyone who has done more than an hour of research knows that CPU mining is not profitable: the simple cost to own/run a machine would be more than what you could mine in Bitcoins. But what if you had 10 machines, or 100 and you didn’t have to worry about the cost of running them? The first idea that popped into my (and hopefully many other college students’) head was: I should try this on campus! … So I did. Specifically, at the University of Colorado at Boulder.
How to not be stupid: don’t do this if you are still a student or in any way dependant on the academic organization that you are mining at. Although I wouldn’t go so far to say that it is “stealing” (especially if they are like CU Boulder and leave all of their computers running 24/7 anyways) they definitely won’t like it. But my thought was: worst case-scenario I will have to give “back” the money made from the mining.
The first hurdle to get over was figuring out if the permissions/firewalls on campus computers would ever let me start mining… I got started with mining the same way any good hacker gets started with anything: Google. By far the best (fastest, most concise) article I found was How to Mine Bitcoins by John Biggs. From what he described, I needed a wallet (I used Coinbase) a pool (I decided on two: Slush’s pool andBitMinter) and a miner: I tried several different Miners that John Suggested (GUI Miner, CGMiner, etc…) but the one that finally worked was BFGMiner.
Once I had a single computer actually mining, it was time to optimize. Getting optimization config files for BFGMiner is a bit of a clumsy task when working on a single CPU machine: the hashrate is going to be low, very low… Once I had my config file up and running the most I could get out of a single machine was 30Mhps (AKA next to nothing). The good thing was, once I had my config file set up, all I needed to do was drop BFGMiner on three flash drives, log into every computer in the room, pop the drives in and doubleclick to get up and running!
I wanted to be thorough in my “experiment” so I went on a Friday night and started mining from almost every computer that I had access to in the Engineering Center/EC (about 100 total). If you are/have ever been an Engineering student, you know that it is more than a 5 day/week job: usually the EC is full on weekends as well. So how could I be relatively sure that no-one would touch the computers for a while? Well, I waited until the weekend before New Years, and all through the EC, not a keyboard was stirring, not even a mouse… *Mice FTW!* So this meant that I not only had the weekend, but potentially a couple weeks of open mining!
I watched my mining progress obsessively all weekend, and was pushing ~3,000Mhps most of the time (not too shabby for CPU)! But that Tuesday, everything stopped. No, certain miners didn’t drop out, I mean everything stopped within a 30 minute time period. Uh-oh O_o!
I figured that this meant the IT department had caught on (OK a single student is logged in to every computer in the EC how hard can it be to figure out that something is wrong?) and was a bit worried, but then I referred back to “how to not be stupid”, analyzed my situation again, and felt better.
In total, I was able to mine 0.00289624 BTC over the course of ~4 days from ~100  computers. If you do the math with bitcoin prices today ($811) that adds up to $2.35 (which isn’t even enough to go over the .01 transfer threshold, so I actually didn’t get a dime). WOW! … Not. If I hadn’t got shut down, I could have mined through break and got another 3 weeks (let’s say 20 days) which could have been as much as $15 total… Since I spent ~5 hours researching, setting up and monitoring my progress, this would come down to $3/hr. And even if I somehow ran the miners in the background throughout the year and neverhad to change update or work on any of the computers, I would still be making ~$240/year. That’s pretty shitty considering all of the “even if”s.
As it turns out, I won’t be quitting my day job anytime soon  to travel the country and mine bitcoins off university computers, regardless of my distaste for higher education, and you shouldn’t either.
Until next time…

An interesting bit *BTC pun FTW* of follow up
I received an email this morning from a nice man at UCB OIT (Office of Information Technology) reading the following:
The IT Security Office received a report of Bitcoin mining occurring on numerous computers in the Engineering labs during the period of December 27th through the 30th. Upon further investigation, it was determined that your account was logged into all of the lab computers. This behavior constitutes a violation of campus Acceptable Use of IT Resources policy which forbids the use of campus IT resources for commercial purposes. Future violations will be reported to campus police and treated as criminal trespass. If you feel that this report was in error please contact IT Security at security@colorado.edu.
 Definitely a good call on the “infraction” citing the “commercial purposes” clause which generally includes: monetary gain from the direct or indirect use of campus resources. However, not quite sure about the “criminal trespass” threat. Perhaps this is generally the case for anyone who is not a CU student being on campus, but I find that hard to believe as it is a public university. The appropriate course of action seems to be revoking my access to university computers (I am yet to find out if that has been done). This seems a bit analogous to the situation of bringing criminal justice into sporting events: at the end of the day it’s all just fun and games…
Slightly jaded by the threat, but at least it was a threat and not a course of action… I still have a few tricks up my sleeve that CU doesn’t want to deal with any time soon!

Zynga Links Up With BitPay For A Bitcoin Payment Test In FarmVille 2,CityVille And Other Web Games


Gaming giant Zynga has started to accept the cryptocurrency as a payment option for those buying tokens for virtual goods on the web versions of FarmVille 2, CastleVille, ChefVille, CoasterVille, Hidden Chronicles, Hidden Shadows and CityVille. It makes Zynga the first major gaming company to accept Bitcoin.
Zynga posted the news first on Redditrather than release an official announcement. It is calling this a “test” being run in partnership with BitPay — the startup backed by the likes of theFounders Fund and Li Ka-shing that is vying to be the “PayPal of the Bitcoin world.”
“We wanted to share with the r/bitcoin community that Zynga Inc. (NASDAQ: ZNGA) is now conducting a Bitcoin test with BitPay (https://bitpay.com/), a leading Bitcoin service provider, in select Zynga.com web games,” Zynga wrote in a post on Reddit.
“In response to Bitcoin’s rise in popularity around the world, Zynga, with help from BitPay, is testing expanded payment options for players to make in-game purchases using Bitcoin. The Bitcoin test is only available to Zynga.com players playing FarmVille 2, CastleVille, ChefVille, CoasterVille, Hidden Chronicles, Hidden Shadows and CityVille. The games can be accessed at http://zynga.com.
“Zynga is always working to improve our customer experience by incorporating player feedback into our games. We look forward to hearing from our players about the Bitcoin test so we can continue in our efforts to provide the best possible gaming experience.”
We have tried buying tokens for the games ourselves and confirm that Bitcoin is coming up as an option in the UK — meaning that it’s likely that this is a global rollout.
We have reached out to Zynga to ask whether it plans to extend this to other games — namely those on mobile and its real-money gambling effort, currently live in the UK.
On the mobile front, considering that Zynga has a huge business on iOS devices, extending Bitcoin acceptance there could prove problematic, considering that Apple has recentlyshown that it does not support Bitcoin transactions.
Up to now, Bitcoin has not made much headway in the world of gaming, although it is seeing some traction in online gambling, where one Bitcoin-wielding player netted a $1.3 million winon one Bitcoin-based gambling site.
One of the attractive points about Bitcoin compared to more established currencies and payment platforms is that transaction fees tend to be lower than those of platforms that transact in more established currencies like dollars.
The deal is a nice coup for BitPay, which in December said it had processed $100 million in transactions in 2013. The startup has largely grown on the back of partnerships with merchants to process payments for things like electronics, precious metals, “and other low-margin products.” These merchants, the company has said, see “a large increase in profitability by accepting Bitcoin payments.”
That should come as good news for Zynga, which is focused on cutting costs while it grows revenues. The company was once a rising star with big social gaming hits like Farmville that people played via Facebook.
More recently, it’s fallen on harder times with a massive drop in users — its last quarterly report noted that daily active users were halved to 30 millioncompared to a year ago, with falling sales alongside that — as consumers flock to newer casual games and newer experiences from other publishers like King.com and Supercell.
The company has been trying hard to shore up its business and recover,appointing Microsoft veteran Don Mattrick as its CEO to replace founder Mark Pincus, laying off staff, and shuttering unprofitable games. In that vein, adding Bitcoin acceptance may not translate into billions more in sales, but it could give the company a little burnish of good PR among investors for being an early mover and innovator, as well as a boost of credibility among Bitcoiners who might come to play on the platform as a result.

Bitcoin Big Hit with Developers: Predicting the future with Github

blog-chart-watermark-50
This chart describes the number of Github projects in existance (y axis) throughout the last couple of years (x-axis) that reference selected keywords. It gives us a pretty good idea of how big a hit bitcoin is with developers. But let’s back up a little bit.

Bitcoin Pulse

My friend Tony and I (Flavio) recently launched Bitcoin Pulse to monitor how bitcoin is growing as a technology. We built this because we wanted this for ourselves. Trying to understand how bitcoin is growing as a technology and as a way to exchange actual goods versus just being a store of value or even a way to get rich quick speculation.

What is Developer Mindshare?

To us, one of the most important ideas that can be indicators predicting the success of a new technology platform is what we call Developer Mindshare.
“The best way to predict the future is to invent it.” – Alan Kay, 1971
We believe that hackers are building the future. They are the ones that are building new technology everyday. By that virtue, they are the first ones to play around when new ideas come around and with their builder mindset, they are the first ones who can picture the myriad of ways a new technology can be used. So we believe that measuring Developer Mindshare is one of the best indicators of how successful technology platforms will be adopted in the market.
We define Developer Mindshare as the amount of attention and effort developers are devoting to using and improving certain technologies and platforms.

Now how can we measure Developer Mindshare?

We think that a good proxy for Developer Mindshare is developers’ activity on GitHub. These days, most developers (or at least the ones working with modern tools) have a GitHub account, with many publicly sharing their own projects or contributing to open source projects. GitHub is also the place where many startups host their own private source code.
GitHub then, can be a great place to start looking at what are the next big things. One way we can measure developer mindshare is to look at what languages, platforms and technologies devs are using for their open source projects.
For this specific case, we ran a simple query that tells us how many projects reference Bitcoin on GitHub. The growth chart is very interesting.

What are the limitations of this approach?

As with any approximation, analyzing GitHub data has its limits. An important one is that we only have access to the open source projects on GitHub. We don’t know what most developers are using in the close-source projects they have. But in a way, the open source contributions are even better: What technologies are they so excited about to use that they do it in their free time? Surely, those technologies must have some future promise?
It is worth noting that this simplistic approach does not gives us totally exact values due to the generic nature of the queries. As such, these values should be used as a rough way to see how things are moving.

Virality

The interesting thing about developer mindshare is that it is to some degree a viral phenomenon. When more developers start using a certain technology, they tend to build tools around that technology to make it easier to use – think of libraries to interface with more computer languages, UI/UX libraries, patches, integrations and so forth. And through that, they make the original technology even more useful, thus adding value to the entire ecosystem around that technology. This again makes it easier for new developers and entrepreneurs to get started using that technology.

Bitcoin vs Stripe vs Paypal

In order to be able to quantify the general level of interest around Bitcoin, we thought it would be interesting to compare Bitcoin with Stripe and Paypal. Obviously this is a bit of an apple to oranges comparison, since Stripe is a payment processor for credit cards, Paypal a wallet and a payment processor and Bitcoin a technology and a currency / value storage. But we think the relative growth of those platforms is something that can yield some insight into what is rising on mindshare.

So what have we found?

The chart above says it all, but here’s for people who want numbers:
In the 30 days from November 15th to December 15th, Paypal grew by 4.4%, Stripe by 6.3% and Bitcoin by 17.8%! In other words,
Bitcoin projects on Github are growing 4 times as fast as Paypal projects and almost 3 times as fast as Stripe projects.

Bitcoin is the Linux of payments. And its killer apps will be for US dollars.

bernanke-ronpaulI was scanning the news the other day, and someone on Hacker News mentioned that half the items above the fold on StreetEYE were about Bitcoin. And I said to myself, I haven’t seen the neckbeards this excited since the early days of Linux.
And it hit me, Bitcoin is the new Linux.
Go back to 1998, the days of The Cathedral and the Bazaar and the ‘Halloween Document’, and open source zealots were gleefully foreseeing the day when freedom-loving hackers would take down the evil Microsoft empire.
Linux was how virtuous hackers were going to end the hegemony of robber barons who stifled freedom and innovation and extracted monopoly rents.
And a glorified screwdriver shop called VA Linux went public at $30 and hit $320 on its opening day.
And 15 or so years later, what happened? Well, VA Linux is now pretty much forgotten1.
And yet, Linux won the Internet. Microsoft has lost relevance. Linux underpins the Web, sites like Google and Amazon, devices like Android and Kindle. Apple is still (even more) proprietary, but everything they do is built on Unix foundations.
Where is the promised utopia? Isn’t it just “new boss, same as the old boss?” Sure, the world is a better place because the OS and the Web are commoditized, not Bill Gates’s private playground. There is more innovation because people don’t fear everything they invent will become a bundled Windows OS feature.
Linux is the ubiquitous plumbing of the Internet, but does it drive the tech agenda? The tech game is basically the same, isn’t it?
Two killer apps built around Linux are Android and Amazon Web Services (which has many of the network and platform effects of an OS). How different are they from the old Microsoft platform? Like the old Microsoft ecosystem, Android and AWS are open enough that people can build great software and services on top of them, and yet closely directed by a benevolent (we hope) dictator for life with a strong financial interest in their success.
And very closed, proprietary ecosystems are still around: only Apple can make an IOS device, and only Apple can decide what software can run on those devices. Not to mention Linux powering numerous completely closed devices and mostly closed social platforms like Facebook.
Linux ‘won,’ and its killer apps are not-totally-open platforms not all that different from Microsoft’s.
And so I predict, the killer app for Bitcoin is the US dollar.
The open payment API and public blockchain are innovative and have applications for things like property records, stock transfer agents, etc.
The money unit, on the other hand, seems like the biggest step backwards in money since the Rai Stones of Yap (pictures). Like the Rai stones, much greater resources have to be spent to manufacture Bitcoin than the bits are actually worth. And moving them around securely and conveniently is not as easy as it should be.
There are a lot of currencies one can exchange for goods and services: dollars, yen, euros, rubles, subway tokens/stored value cards, Club Med beads, frequent flier miles. And yet, 81% of international trade is settled in dollars, and 62% of central bank reserves are in dollars, both numbers which do not appear to be falling rapidly. The market has sort of spoken.
Thought experiment: What if a comic book supervillain (or superhero) decided to build a replica Fed across from the Eccles building and offer its own currency, payment system, and proposed to supplant dollars. What do you think would happen… would no one adopt it, would it co-exist in some way with dollars, or would it take over, and what would it take for it to do that? A cheaper payment system? A more open API? A system designed to maintain the currency’s value? What kind of value proposition improvement does it normally take to overcome an entrenched competitor?
And Bitcoin doesn’t have The Joker going “Who do you trust! … I’m giving away free money.” Just the opposite! There’s an inherent conflict between managing a currency to be liquid and flexible and support a growing economy, and being an asset which is a long-term store of value. Some currencies, such as the old Deutschemark, the Swiss franc were managed with a sharp focus on being stable stores of value; others, such as the yen, with more focus on supporting export economies. Being an attractive store of value has a downside for real economies using the currency, and Bitcoin is to the Swiss franc like Mr. Potter is to George Bailey.
As a medium of exchange, a store of value, and a unit of account, Bitcoins are a giant fail. There is no case they can or every will hit kind of 10x improvement you look for in disrupting an entrenched incumbent. And what if that competitor writes and enforces the laws, and has an NSA and nuclear aircraft carriers?
And there is also no chance a Bitcoin ecosystem can be tolerated at scale without imposing the exact same terms and conditions as dollars. If our supervillain gets everyone to adopt his currency, the end game is imposing all the same taxes, reporting, anti-money-laundering regs on Bitcoins as on USD. Otherwise, you know the last act is the Navy SEALs clambering down ropes into his replica Fed and blowing the place up.
Please. If Bitcoin is the future Linux, and not the future Segway, it has to lose the Bitcoins.
Just as people are creating Bitcoin-like DogecoinPonzicoin2, etc., the future is Bitcoin-like blockchain APIs to transfer all manner of assets, stocks, real estate deeds, and above all, the most popular asset in the world, the US dollar.
Every super-amazing feat, new contracts, cheap international transfers, low transaction costs, etc. that can be accomplished with Bitcoin can also be accomplished with Bit-cents – dollars in an account at the Fed, or a bank, or in a vault, transferred using the Bitcoin API.
You want an international transfer, set up a pool of pesos tied to a Bitcoin API, and a pool of dollars, and an exchange where you offer to exchange one for the other, and any time someone buys pesos for dollars, they have to be paired with someone buying dollars for pesos at a market-clearing FX rate.
The only advantage of the Bitcoins themselves is that government is out of the loop, which is sort of a bug as far as the tax collector is concerned, never mind that seignorage goes toward burning electricity instead of building schools, roads, and the occasional aircraft carrier to keep that economy safe.
Like Linux, Bitcoin needs to become the plumbing, and start working within existing financial frameworks.
So, hackers, please. Stop designing mining ASICs, and burning up the planet. If it’s about better financial institutions, access to electronic payments for the unbanked, more efficient payments, financial services without too-big-to-fail financial institution rent-seeking, then start building the startups that will enable them. Show us how Bitcoin can make the world a better place. Stop trying to make fiat currency worthless, and unleash the kind of financial disruption and chaos Bitcoin is supposedly designed to prevent. Don’t try to ‘end the Fed’ Just build things people love, to do the things they need to do with the assets that already matter. Otherwise it’s just about disruption fetishism, geek privilege, and slightly harebrained ideology.
Bitcoins must die, in order that Bitcoin may live. RIP Bitcoins, long live Bitcoin.
Everything that disrupts at one level, must sustain at a different level.
And thus, the world must change, in order that it may remain the same.
1VA Linux is now Geeknet, with a market cap of $120 million or so. Their hardware is gone, GitHub has eclipsed VA Linux’s SourceForge, and Hacker News and TechMeme have displaced their SlashDot paleo-news-aggregator.

2Ponzicoin is not intended to be construed as an actual crytpocurrency.

First time in the country, ED raids a Bitcoin seller in Ahmedabad

A couple of days after the Reserve Bank of India issued an advisory to public not to indulge in buying-selling of Bitcoins, the first raid in India was undertaken in Ahmedabad by Enforcement Directorate (ED) on an entity that provide platform to trade in this illegal but virtual currency.

On Thursday, ED raided the premises of Mahim Gupta in Bopal area of the city who provides trading platform through his website -‑ buysellbit.co.in. During the preliminary investigation, the ED found that it is in clear violation of Foreign Exchange Management Act (FEMA) rules of the country as central bank does not provide permission to indulge in such transactions.

“We have found that through the website 400 persons have recorded 1,000 transactions that amount to a few crores of rupees. We are gathering the data of the transactions, name of the people who have transacted in the virtual currency from Gupta’s server that is hired in the US. At present, we believe that this is a violation of foreign exchange regulations of the country. If we are able to establish money laundering aspect then he can be arrested,” said a top ED official.

As per sources, a separate raid was also conducted in Satellite area of the city, however, the person the investigation agency was looking for could not be found. “When we reached his office, he was not there. We have sealed the premises,” the official added.

The value of transactions is not known as each transaction will be verified by the investigating agency. However, it is likely to be around Rs20-30 crore. “Value of transaction is one aspect. Being a virtual currency its transfer and settlement is done online. No country has legalised Bitcoin as of now because of its opaque nature. The biggest threat is that without recording your transaction in official foreign currency platform money can be transferred like hawala with the use of this transaction. We are examining such instances, if any, here,” the official said.

Sources also added that there are a handful of entities that provide trading in the virtual currency in India. “I think there are only five entities. Of these, we believe two are operating from Ahmedabad. We believe that they have channel of agents or people who promote the use of such currency but entities that provide online platform are few,” official said.

Because of complex nature of transaction and high level information technology security involved ED is taking help of company called ECS Corporation that specialises in forensic audit and IT technology.

Virtual currency trade is 3-year-old
Bitcoin came into existence just 3-year ago. It is a virtual currency that can be generated through complex computer software systems with solutions shared on a network. Despite new in existence, Bitcoin has already become the world’s most expensive currency and its per unit value soared past USD 1,000 level or about Rs 63,000 recently, although the prices have now slipped to Rs46,600.

21 Million Dogecoins Stolen



Take two of 2013's biggest Internet sensations -- bitcoins and the Shiba Inu puppy nicknamed "Doge" -- and smash them together. What you get is Dogecoin, a virtual currency that was hacked during the holidays.
Although 21 million dogecoins were lost in the heist, they only amounted to about $12,000 in value. In comparison, bitcoins are now valued at close to $750 a piece, and a bitcoin hack in Novemberlost 4,100 bitcoins, totaling $1.2 million.
The hack caught Jackson Palmer, a co-founder of the currency, by surprise. "It's interesting that there has been a focus [on dogecoins] in the short two or three weeks we've been up and running," he said. "I think it's crazy that it can happen, but maybe these hackers are trying to get in early."
He and the other co-founder of Dogecoin, Billy Markus, are looking to beef up security in the next month, Palmer added.
Even though the idea of dogecoins started as a joke, Palmer said, it has grown in popularity. "For the majority of their people, it's their first experience with cryptocurrency," he told ABC News. "It's a lot more accessible and the majority of people are having a lot of fun with it."
A single dogecoin might only be worth a fraction of a penny, but Palmer does see it being useful as a currency, though maybe not in the real world.
"People are trading coins for small purchases, like in an online game where you can purchase a different set of armor," he said. "I think that's a really good place [for Dogecoin]."

Overstock.com Reportedly Plans To Accept Bitcoin In 2014

Overstock.com is moving to accept Bitcoin as payment in 2014, the CEO told The Financial Times. Apparently the retailer has the ambition to become the first major online retailer to accept the digital currency. And it very well could be. No other major retailer has announced a similar plan yet. However, put away your digital wallet for the time being. The retailer doesn’t expect to start accepting Bitcoin until the second half of 2014, by which time, Dogecoin could eclipse its popularity.
This announcement comes just days aftera major shakeup in the Bitcoin ecosystem as China’s largest BTC exchange stopped accepting deposits in Chinese yuan, causing Bitcoin’s monetary value to drop 50% in a few hours.
Overstock saw just over $1 billion in revenue last year. The company trades on NASDAQ and its stock price is up 109.29% on the year. The news about accepting Bitcoin caused the shares to jump 7.77% on the day.
Overstock CEO Patrick Byrne stated that a healthy monetary system isn’t based off of an upside pyramid or the whim of a government official. Bitcoin fits that bill. Byrne stated that when Overstock starts accepting Bitcoin, the retailer would bank the digital currency in the event derivatives (such as Dogecoin) are increasing in popularity. If offshoots fail to gain steam, Overstock would transfer the Bitcoins into dollars on a daily basis, essentially day trading the Bitcoin income.
In the latter half of 2013, a number of retailers have moved to accept Bitcoin as payment with OkCupid, Namecheap and Humble Bundle among the list. Charities are also latching onto the digital currency since it lacks fees usually associated with monetary donations. If Overstock follows through with its plan, it would be come the largest U.S.-based retailer to accept Bitcoins. That is, of course, if Amazon or the like doesn’t beat them to the punch.

Bitcoin Is Evil



It’s always important, and always hard, to distinguish positive economics — how things work — from normative economics — how things should be. Indeed, on many of the macro issues I’ve written about it has been obvious that large numbers of economists can’t bring themselves to make that distinction; they dislike activist government on political grounds, and this leads them to make really bad arguments about why fiscal stimulus can’t work and monetary stimulus will be disastrous. I don’t, by the way, think that this effect is symmetric: although people like Robert Lucas were quick to accuse people like Christy Romer of fabricating macro arguments to support a big-government agenda, this didn’t actually happen.

But I come now to talk not about macro but about money — specifically, about Bitcoin and all that.
So far almost all of the Bitcoin discussion has been positive economics — can this actually work? And I have to say that I’m still deeply unconvinced. To be successful, money must be both a medium of exchange and a reasonably stable store of value. And it remains completely unclear why BitCoin should be a stable store of value. Brad DeLong puts it clearly:
Underpinning the value of gold is that if all else fails you can use it to make pretty things. Underpinning the value of the dollar is a combination of (a) the fact that you can use them to pay your taxes to the U.S. government, and (b) that the Federal Reserve is a potential dollar sink and has promised to buy them back and extinguish them if their real value starts to sink at (much) more than 2%/year (yes, I know).
Placing a ceiling on the value of gold is mining technology, and the prospect that if its price gets out of whack for long on the upside a great deal more of it will be created. Placing a ceiling on the value of the dollar is the Federal Reserve’s role as actual dollar source, and its commitment not to allow deflation to happen.
Placing a ceiling on the value of bitcoins is computer technology and the form of the hash function… until the limit of 21 million bitcoins is reached. Placing a floor on the value of bitcoins is… what, exactly?
I have had and am continuing to have a dialogue with smart technologists who are very high on BitCoin — but when I try to get them to explain to me why BitCoin is a reliable store of value, they always seem to come back with explanations about how it’s a terrific medium of exchange. Even if I buy this (which I don’t, entirely), it doesn’t solve my problem. And I haven’t been able to get my correspondents to recognize that these are different questions.
But as I said, this is a positive discussion. What about the normative economics? Well, you should read Charlie Stross:
BitCoin looks like it was designed as a weapon intended to damage central banking and money issuing banks, with a Libertarian political agenda in mind—to damage states ability to collect tax and monitor their citizens financial transactions.
Go read the whole thing.
Stross doesn’t like that agenda, and neither do I; but I am trying not to let that tilt my positive analysis of BitCoin one way or the other. One suspects, however, that many BitCoin enthusiasts are, in fact, enthusiastic because, as Stross says, “it pushes the same buttons as their gold fetish.”
So let’s talk both about whether BitCoin is a bubble and whether it’s a good thing — in part to make sure that we don’t confuse these questions with each other.

Into the Bitcoin Mines



Video | Mining for Bitcoins in Iceland At a secure facility that was once a NATO base, computer servers run around the clock mining bitcoins. The company behind the operation relies on cheap energy to turn processing power into cash.

On the flat lava plain of Reykjanesbaer, Iceland, near the Arctic Circle, you can find the mines of Bitcoin.
To get there, you pass through a fortified gate and enter a featureless yellow building. After checking in with a guard behind bulletproof glass, you face four more security checkpoints, including a so-called man trap that allows passage only after the door behind you has shut. This brings you to the center of the operation, a fluorescent-lit room with more than 100 whirring silver computers, each in a locked cabinet and each cooled by blasts of Arctic air shot up from vents in the floor.
These computers are the laborers of the virtual mines where Bitcoins are unearthed. Instead of swinging pickaxes, these custom-built machines, which are running an open-source Bitcoin program, perform complex algorithms 24 hours a day. If they come up with the right answers before competitors around the world do, they win a block of 25 new Bitcoins from the virtual currency’s decentralized network.
The network is programmed to release 21 million coins eventually. A little more than half are already out in the world, but because the system will release Bitcoins at a progressively slower rate, the work of mining could take more than 100 years.



The scarcity — along with a speculative mania that has grown up around digital money — has made each new Bitcoin worth as much as $1,100 in recent weeks.
Bitcoins are invisible money, backed by no government, useful only as a speculative investment or online currency, but creating them commands a surprisingly hefty real-world infrastructure.
“What we have here are money-printing machines,” said Emmanuel Abiodun, 31, founder of the company that built the Iceland installation, shouting above the din of the computers. “We cannot risk that anyone will get to them.”
Mr. Abiodun is one of a number of entrepreneurs who have rushed, gold-fever style, into large-scale Bitcoin mining operations in just the last few months. All of these people are making enormous bets that Bitcoin will not collapse, as it has threatened to do several times.



Just last week, moves by Chinese authorities caused the price of a Bitcoin to drop briefly below $500. If the system did crash, the new computers would be essentially useless because they are custom-built for Bitcoin mining.
Miners, though, are among the virtual-currency faithful, believing that Bitcoin will turn into a new, cheaper way of sending money around the world, leaving behind its current status as a largely speculative commodity.
Most of the new operations popping up guard their secrecy closely, but Mr. Abiodun agreed to show his installation for the first time. An earnest young Briton, with the casual fashion taste of the tech cognoscenti, he was a computer programmer at HSBC in London when he decided to invest in specialized computers that would carry out constant Bitcoin mining.
The computers that do the work eat up so much energy that electricity costs can be the deciding factor in profitability. There are Bitcoin mining installations in Hong Kong and Washington State, among other places, but Mr. Abiodun chose Iceland, where geothermal and hydroelectric energy are plentiful and cheap. And the arctic air is free and piped in to cool the machines, which often overheat when they are pushed to the outer limits of their computing capacity.



The operation can baffle even those entrusted with its care. Helgi Helgason, a burly, bald Icelandic man who oversees the data center that houses the machines, said that when he first heard that a Bitcoin mining operation was moving in he expected something very different. “I thought we’d bring in machines and put bags behind them and the coins would fall into them,” said Mr. Helgason, with a laugh.
Since then, the education he has received about Bitcoins has been enlightening, but only to a point.
“It’s a strange business,” he said, “and I can’t say that I understand it.”
Until just a few months ago, most Bitcoin mining was done on the home computers of digital-money fanatics. But as the value of a single Bitcoin skyrocketed over the last few months, the competition for new coins set off a race that quickly turned mining into an industrial enterprise.
“Even if you had hardware earlier this year, that is becoming obsolete,” said Greg Schvey, a co-founder of Genesis Block, a virtual-currency research firm. “You are talking about order-of-magnitude jumps.”
The work the computers do is akin to guessing at a lottery number. The faster the computers run, the better chance of guessing that right number and winning valuable coins. So mining entrepreneurs are buying chips and computers designed specifically — and only — for this work. The machines in Iceland are worth about $20,000 each on the open market.
The energy required to run these computers is huge, and has led to criticism that Bitcoin mining is wasteful, not to mention socially useless. But Mr. Abiodun prides himself on using renewable power, at least in Iceland.
When Mr. Abiodun first heard about Bitcoin mining in 2010, he thought it was a scam. Begun in 2009 as the imaginative creation of an anonymous programmer (or group of programmers) known as Satoshi Nakamoto, it was initially little more than a tech world curiosity. As early users connected their computers into the network, they became a part of the decentralized infrastructure that hosts Bitcoin’s open-source program. The computers joining the network immediately began capturing virtual coins. The network’s protocol was designed to release a new block of Bitcoins every 10 minutes until all 21 million were released, with the blocks getting smaller as time goes on. If the miners in the network take more than 10 minutes to guess the correct code, the Bitcoin program adapts to make the puzzle easier. If they solve the problems in less than 10 minutes, the code becomes harder.
Mr. Abiodun’s opinion of Bitcoin changed in January, when he saw the price rising. He installed a free application on his home computer that linked him into the Bitcoin network and set it to mining, harnessing the power of his graphics card, which is the part of a normal computer best suited to doing the code work.
Mr. Abiodun’s computer was in the guest room of his house in southeast London. Working at HSBC during the day and tinkering with his Bitcoin system at night, he realized if he wanted to make any money, his computer would have to run around the clock.
The constant computing, however, overheated the graphics card and pushed the computer’s exhaust fans into overdrive. When he added another graphics card, then a new computer, the room became too noisy for guests to sleep, and the windows had to be kept open to release the heat. That did not make his wife, Gloria, who was pregnant at the time, very happy.
“It just created a scenario where there was no way our parents would come over to stay,” he said. “I did offer to put her parents in a hotel, but that didn’t go down well.”
Mr. Abiodun’s wife finally gave him an ultimatum — either the computers had to go, or he did. At the same time, he was making money, and friends were asking if they could invest in his mining operation.
In February, Mr. Abiodun used the investors’ money to buy machines from a start-up dedicated solely to manufacturing specialized mining computers. The competition for those computers is so intense that he had to pay for them and wait for delivery.
When the delays became lengthy, however, he went on eBay and paid $130,000 for two high-powered machines, which he set up in June in a data center in Kansas City, Kan.
This was the beginning of Mr. Abiodun’s company, Cloud Hashing, which rents out computing power to people who want to mine without buying computers themselves. The term hashing refers to the repetitive code guessing that miners do.
Today, all of the machines dedicated to mining Bitcoin have a computing power about 4,500 times the capacity of the United States government’s mightiest supercomputer, the IBM Sequoia, according to calculations done by Michael B. Taylor, a professor at the University of California, San Diego. The computing capacity of the Bitcoin network has grown by around 30,000 percent since the beginning of the year.
“This whole new kind of machine has come into existence in the last 12 months,” said Professor Taylor, who is studying mining hardware. In the chase for the lucky code that will unlock new Bitcoins, mining computers are also verifying and assigning unique identifying tags to each Bitcoin transaction, acting as accountants for the virtual currency world.
“The network is providing the infrastructure for making sure the currency is being transferred between people according to the rules,” Professor Taylor said, “and making sure people aren’t creating currency illegally.”
Even before Mr. Abiodun’s machines in Kansas City were up and running, it was clear that they wouldn’t be enough. So he ordered about 100 machines from a start-up in Sweden and, in October, had them moved to the facility in Iceland. In just a few months, that installation has generated more than $4 million worth of Bitcoins, at the current value, according to the company’s account on the public Bitcoin network.
At the end of each day, the spoils are divided up and sent to Cloud Hashing’s customers. Last Wednesday, for example, the entire operation unlocked 225 Bitcoins, valued at around $160,000 at recent prices. Cloud Hashing keeps about 20 percent of the capacity for its own mining.
The unregulated Bitcoin-mining industry is ripe for abuse, and ventures that sound similar to Cloud Hashing have turned out to be scams. Mr. Abiodun’s company has proved itself real, but it is still unclear if it is a good deal for customers. Cloud Hashing charges $999 to rent a tiny portion of the company’s computing power for one year. That’s an expensive price for the computing capacity they are getting, but Mr. Abiodun argues that it’s a good value because individual miners would not be able to buy his modern machines outright. It’s a little like buying a fractional ownership in a private jet; you might not want responsibility for the jet itself, and it’s out of your price range anyway. He also says he provides the maintenance and keeps away thieves and hackers.
Some Cloud Hashing customers have also complained on Internet forums that it can be hard to get a response from the company when something goes wrong. But this has not stopped new contracts from pouring in. Cloud Hashing now has 4,500 customers, up from 1,000 in September.
Mr. Abiodun acknowledges that the company has not been prepared to deal with its rapid growth. He said he had used $4 million raised from two angel investors to add customer service representatives to offices in Austin, Tex., and London. Cloud Hashing is now preparing to open a mining facility in a data center near Dallas, which will hold more than $3 million worth of new machines being produced by CoinTerra, a Texas start-up run by a former Samsung chip designer.
The higher energy costs — and required air-conditioning — in Texas are worth it for Mr. Abiodun. He wants his operation to be widely distributed in case of power shortages or regulatory issues in one location. But he is also expanding his Icelandic operation, shipping in about 66 machines that have been running for the last few months near their manufacturer in Ukraine.
Mr. Abiodun said that by February, he hopes to have about 15 percent of the entire computing power of the Bitcoin network, significantly more than any other operation.
Inside the Iceland data center, which also hosts servers for large companies like BMW and is guarded and maintained by a company called Verne Global, strapping Icelandic men in black outfits were at work recently setting up the racks for the machines coming from Ukraine. Gazing over his creation, Mr. Abiodun had a look that was somewhere between pride and anxiety, and spoke about the virtues of this Icelandic facility where the power has not gone down once.
“We don’t want downtime — ever, never,” he said. “Not with what we paid. Not with Bitcoin.
