Bitcoin in 2012: By the Numbers

Our humble digital currency continued to show resilience in 2012, growing in all respects and steadily building its user base. The expression "slow and steady" is a fitting descriptor; let's take a look at the stats:



The rate of downloads of the main client increased slightly toward the latter half of the year, with approximately 70,000 per month. 




The number of users of the popular "My Wallet" service provided by blockchain.info has grown nearly exponentially, especially over the last month. Blockchain.info arguably has the most user-friendly mobile app for Bitcoin, which has likely contributed to the success shown in this chart.

Another popular client, MultiBit, receives approximately 200 downloads per day (6000 per month), which is quite respectable.



Always a favourite statistic is the exchange rate. Over the past year Bitcoin's value when compared to the US Dollar, and most other currencies, increased steadily, though there was a large spike and subsequent dip in August.


Interestingly, the current market cap is actually at a peak for 2012, exceeding the spike in August. This can be attributed to the fact that tens of thousands of Bitcoins have been introduced into the economy since August, though now at the slower rate of 25 per block.

Bitcoindata.net has been tracking several other statistics, including the number of items listed at Bitmit (an auction site that operates in Bitcoin), the number of users at Ogrr (an MMORPG marketplace), and the number of views of the "What is Bitcoin" YouTube video. All three of these have shown steady growth over the past year.




Bitcointalk forum membership growth and subscribers to the Bitcoin sub-reddit are also increasing steadily (charts again courtesy of Bitcoindata.net):



In the online gambling scene, things appear to be looking up as well. Bitcoin's top poker site, SealswithClubs, is gaining new users on a daily basis, with attendance at the tables on the rise:


Even the Bitcoin discussion on the TwoPlusTwo forums, the most popular poker discussion forum on the 'net, has 3,000 posts and 165,000 views!

Other notable stats:

Bets made at SatoshiDice.com: 2,354,830
Merchants using Bit-Pay: 1000+ in 98 countries (as of Sept 2012)

All-in-all, a very impressive year for Bitcoin. Here's to an even stronger performance in 2013!

Happy Holidays to all the Bitcoiners out there, and may your 2013 be full of independent financial awesomeness!

Got the Smarts? Put your Bitcoins on the Line at BitTrivia.com

So, there I was, sitting at BitTrivia.com thinking to myself, "more people need to know about this site!"

Opened just two days ago, BitTrivia is exactly what it sounds like, a site where you can put your Bitcoins on the line against others in a no-holds-barred trivia competition. Got the smarts but never had an opportunity to cash-in on your talent? Now you can!



BitTrivia's design is intuitive and enjoyable, giving competitors a satisfying multiplayer experience. I've attended a few trivia nights at the local bar, and I would say that BitTrivia's bank of questions is a little easier than what you would find in a real life trivia competition, with the occasional stumper mixed in with the usual trivia fare.

The site takes a 10% cut of the prize-money, which can be as much as you're willing to bet, multiplied by the number of players who match your bet. If you're not feeling overly brainy, you can bet as little as you wish, but your winnings will never be more than you're willing to risk. Deposits are instant and withdrawals are as well, as long as your deposit has a single confirmation against it.

Update: the site now lets you play on your own!  If you get a question right, you automatically win 0.001 BTC - a great way to earn Bitcoins if you don't already have some.

I suspect the Bitcoin-backed online gaming scene has a lot of room to grow; BitTrivia is definitely a good example of its potential.

Set up your own electronic bitcoin exchange using localbitcoins.com!

Today we have added a new escrow feature to localbitcoins.com. This differs from the previous transaction feature by being completely designed only for electronic money transfers and not for physical cash trades.

The service requires that you have bitcoins in your localbitcoins.com wallet before you can start using it. The escrow service is disabled by default, and currently enabled only for selling advertisements.

The service generates reference messages automatically for the buyer, so that doing the trade is very easy for both the seller and buyer. The buyer has just to pay the invoice automatically generated by localbitcoins.com, and the seller must watch his bank/payment service account and release the funds when they are spotted.

Every trade builds up reputation for both participants. We always suggest to be cautious with first timers - in the bitcoin community, bank account hackers sometimes use services like localbitcoins.com to buy bitcoins. Therefore check the reputation of the counterparty when accepting bank transfers. Banks will notice these transfers usually pretty quickly, about in 0-3 days. With new users with no existing trade volume, it is recommended to wait or ask for additional validation before accepting the transfer.

Of course all the existing features of localbitcoins.com are also integrated with the new process, such as messaging, feedback and SMS/email notifications. You can also specify your price using equations, as before. Examples:


  • Sell for market price, but at least 13.5 USD: max(mtgoxUSD_ask, 13.5)
  • Buy always at competitive but fair rate (EUR): min(min(min(mtgoxUSD, bitstampUSD), USD_24h)*USD_in_EUR, EUR_24h)


Read more about the escrow feature from our guide.

For more examples for equations and all parameters, see our cash exchange guide.

We are developing localbitcoins.com constantly forward, and more features will be coming all the time. Stay tuned!

Watch out with bank transfers!

For all localbitcoins.com users, be very careful when using bank transfers. Localbitcoins.com hasn't been designed with bank transfers in mind in the first place, so we don't have infrastructure for it. Bank transfers can also be chargebacked/accounts frozen like with paypal or credit cards. There are some people using stolen bank accounts to purchase bitcoins from sellers, on localbitcoins.com

If you are going to sell bitcoins with bank transfers, check the profile/feedback beforehand. Watch out with new users. It doesn't hurt to wait or cancel the deal when unsure.

25 Bitcoins per Block - Not Enough for Some Miners

On the 28th of November, the reward for solving a Bitcoin block dropped from 50 Bitcoins to 25 as the first of several programmed Bitcoin inflation controls kicked in. There was rampant speculation on what the immediate repercussions would be at the time of the halving, with some expecting an immediate jump in the exchange rate, and others thinking that miners all over would begin turning off their rigs.

Neither of those predictions came to pass on the 28th, but they might have been correct after all.

Over the last two weeks, the exchange rate has indeed climbed, from about $12.25 USD to $13.50 today. Additionally, the network hash rate has begun to drop off, with the first decrease seen in more than six months. The current difficulty is 3,370,182, and the next could very well be south of 3,000,000, as predicted by the algorithms at BitcoinX at the time of this posting.

The question is, what happens next? My opinion is that we should continue looking to outside influences to determine how the next chapter will play out. Evidently, Bitcoin's popularity is beginning to grow rapidly, which will eventually take the exchange rate, and the difficulty, to new highs in the very new future. What we're seeing today is Bitcoin taking a short breather before the next ramp up, so hang on!

SMS messages not delivered in multiple places

Our SMS service provider twilio, for some reason, has stopped receiving incoming SMS's altogether this weekend. We are looking for alternate provider ASAP.

Edit: now we have implemented Nexmo, and added couple of numbers. THis should help with the situation.

The Localbitcoins.com SMS numbers are+15813330250 (CA), +43676800505463 (AT), +442033222117 (GB), +46769436195 (SE), +16466994674 (US)

These are all normal phone numbers, which don't have any special fees attached to them. Sometimes there might be problems delivering the SMS's, in this case you should try a different number.

I'm Alive!

So, it's definitely been too long since my last post, but I just wanted to let everyone know that I'm still around.

In October I took some vacation from my real job and made my way to San Francisco to meet up with the guys behind 20Mission, including Jered Kenna and Jonathan Ryan Owens. It was fantastic to finally meet some of Bitcoin's personalities in real life, and though they couldn't share a lot of detail with me, it was exciting to hear about some of the projects they have on the go. In the near future I intend on writing up an article on the experience.

Until then, I remain,

SMS Service dysfunctioning in Italy

Some operators in Italy don't seem to transmit SMS messages properly to twilio. Please don't rely on the SMS transaction service if you are doing trading in Italy.

We are trying to resolve the problem as soon as possible.

Start Your Own Money Press

Physical cash is old and well-working concept. It has a good privacy model, it is relatively anonymous and it is easy and fast to use. Physical cash won't go away anytime soon, because it works so well.

However there are some problems, which might become bigger issues in the future. Central banks are always able to print physical money as much as they want, which will cause devaluation of physical cash for everyone. Additionally, even if you believe in central banks, private entities with skills and resources are able to print cash as well. In fact, there already exists counterfeit cash which even skilled experts can't distinguish from goverment-printed money.

Bitcoin solves effectively the counterfeiting problem, or so called double-spending problem. It also removes nicely the need to trust the central bankers. However, being a virtual currency, using bitcoins is often seen much more difficult than using cash or other traditional payment methods.

One nice concept around Bitcoin is a paper wallet. It allows anyone to store bitcoins on a paper, like physical cash. Unlike physical cash, bitcoin paper wallets aren't suitable for large-scale trade, but they have other useful applications:

  • Getting people introduced to bitcoins, a learning tool
  • Relatively secure way to store bitcoins - generate the paper wallets offline on a computer, print them out, and store them in a bank safe
  • Trade in high-trust environment, such as between friends and family
simplest possible bitcoin bank note
The simplest possible bitcoin bank note contains only the private key. You can derive the corresponding Bitcoin address from the private key. However usually it makes sense to include also the corresponding bitcoin address, to make usability easier.

Other than that, only the sky is the limit. Bitcoin paper wallets come in all sizes and forms, and it is also fairly easy to create your own design. You can store any amount of bitcoins on paper wallet - be it one million bitcoins or 0.00000001 bitcoins (one satoshi). You can also load them as you go - it might be useful to have receiving addresses in your wallet, just in case. You can store the private key somewhere else securely.

The best thing about bitcoin paper wallets is that they are not dependant on any of the running bitcoin services, except the bitcoin network itself. Even if invidual web sites come and go, the Bitcoin network highly probably will stay up and running, and you will be able to redeem your bitcoins even aften waiting 10 years.

Printing your own Bitcoin bank notes

Bitaddress.org provides easy way to print your own bitcoin cash. The steps are:

  1. Start your web browser. Use incognito window or similar.
  2. Go to bitaddress.org
  3. Disconnect your computer from the internet
  4. "Paper Wallet" -> "Print"
  5. Clear browser cache and all private data, restart browser
Tinfoil hats will not be happy with these instructions, therefore I have included extra security cautions in the footnote [1].

After printing, you can apply some kind of tamper-evident sticker on top of the private key. Also one option is to laminate the wallets, as I did - it makes them more durable.

Creating your own custom design

Bitaddress.org is just a static html/javascript page, you can download it to your computer and modify the behaviour to match your requirements. The most obvious thing is to create your own design for the bank note.

This can be done with following steps:

  1. Create your custom artwork with any program such as inkscape or photoshop
  2. Export it to png at 795x430 pixels
  3. Convert the png file to base 64 data
  4. Replace the contents of the img tag, id "papersvg" inside javascript 

You can also replace the site logo (id logo), or localize the site to your own language. Then you can upload the html file to your own server, so anyone can use your design to generate bitcoin paper wallets.

Loading and redeeming paper wallets

Naturally any QR-scanning capable bitcoin wallet app can be used to load the paper wallet. Not all apps can be used to redeem the contents. Our easywallet.org web wallet can be used to sweep the transactions from the private key. It works on iPhone and Android, also with one-tap if configured properly. Easywallet.org doesn't import the private keys, it just sweeps the unspent transactions to the wallet address and after that forgets the private key.

[1] Extra security cautions for using bitaddress.org:

  • Use linux from USB stick, such as tails (handy amnesiac distro)
  • Don't connect the printer to a internet connected machine - ever (printer manufacturers are controlled by reptilians)
  • Download the file locally and validate the SHA1 checksum provided by the bitaddress.org author
  • Wrap everything in tinfoil

Easywallet.org supports now private key import

Now you can sweep any bitcoin private key easily to Easywallet.org . This is done easily with mobile phone with QR code scanner, especially with the one-tap feature enabled - import the money to your wallet with just one tap.

The feature doesn't import the private key. It just sweeps all the unspent transactions to your wallet. The private key is instantly forgotten by the service after sweeping, and not logged in any way.

The feature doesn't currently support mini private key format, but the support is coming soon.

This allows easy integration with paper wallets. Our favorite tool for generating paper wallets is bitaddress.org.

The fee for the feature is 0.49% of the transaction sum, and the bitcoin network fees.

Accept Bitcoins On The Restaurant Day


The International Restaurant Day is coming again on next saturday, and hundreds of small restaurants will be popping around the world. The event started from Helsinki, Finland, and has been spreading since then to new countries and cities.

For small-time restaurants, payments are always a problem. Cash is cumbersome, and it is hard to keep enough change for your customers. Accepting credit or debit cards is really expensive, and if you want to set up a temporary restaurant you usually don't want to invest in a credit card terminal.

Bitcoin is nice, because in addition to solving the central banking problem, it also fixes the change money problem, and also it is very easy to accept bitcoin payments. Below I will visit different ways to accept bitcoin payments from your customers.

Easywallet.org - probably quickest and easiest 

All platforms: iPhone, Android, laptops, any device with a web browser

To set up accepting payments, just go to easywallet.org and the service will generate a random web address for you, which is the key to your bitcoins. Bookmark it, and you can start accepting bitcoins. The service supports currency conversions with 24h exchange rate, so you don't need to worry about the exchange rate, and the rate will be fair to both buyer and seller.

From your settings, turn off "Use Static Address". This way the service will generate new address each time you receive payments, allowing you to separate your customers more effectively.

To move your bitcoins elsewhere, you can use QR code scanner on iPhone and Android. You can also send the URL to your email, and handle cashing out from your computer.

Electrum + acceptbit.com

Safe (only receiving), any device with browser, including iPhone, Android and Kindle!

This merchant solution is basic, but it works. Note that this is not a wallet software - it is only for receiving money. You have to pair the web site with an electrum installation.

Android standalone wallets

These are standalone, which means that they store private keys on your device.

BitcoinSpinner - really fast and easy, no block chain download.

Bitcoin Wallet (Schildbach) - oldest and stable. There is block chain download, therefore I can't recommend it to newbies.

Others

Blockchain.info - browser-based, or standalone for Android and jailbroken iPhone. Haven't used it myself, but generally recommended lots in the community.

Electrum - my favourite desktop client. Friendly and instant.

Giving change as bitcoins

You have run out of pocket change and can't give your customer money? Maybe he/she will accept bitcoins. Print some paper wallets from bitaddress.org. When customer requests change, zap change amount worth of bitcoins to a paper, and give the paper to the customer. The customer can cash out his/her bitcoins from his computer at home.

Cashing out bitcoins to euros/dollars/fiat

There are lots of exchanges which allow you to convert your bitcoins to more traditional currencies. My favourite bank transfer-based exchange is bitstamp.net.

However, if you want to spur up the local bitcoin economy, look for a cash dealer at localbitcoins.com - you can also set up your own "selling bitcoins" advertisement, and help local people to get to know bitcoins a little better.

Hope everyone has a great Restaurant Day! If you consider accepting bitcoins and have any questions, send me an email to jeremias.kangas@gmail.com . Feel free to ask anything. Also if you will accept bitcoins on next saturday, give me a note - I can advertise your pop-up restaurant for free :)

Easywallet.org new fee structure

There will be a new a new storage fee for wallets with balance over 12 BTC. The fee will be exactly 0.0335% (0.0335 percent) of the wallet balance, deducted once in a day. For one month (30 days) this equals roughly 1%.

The fee will be effective after 25th november, 2012, 00:00 UTC. For newly created wallets, the fee will be effective immediately.

Note that this affects you only if you store more than 12 BTC in your Easywallet.org wallet.

For storing larger sums of bitcoins, we recommend paper wallets. These can be easily created using bitaddress.org . One of the coming features of easywallet.org will be a better integration with offline paper wallets.

Additionally, because of large amounts of incoming transaction spam, the outgoing transaction fee is raised to 0.003 BTC per transaction. This will also be effective on 25th november.

Our goal with Easywallet.org is to provide the easiest and fastest way to use bitcoins, and to help people to get started with bitcoins.

Localbitcoins.com transaction feature was down on 06/10, now working again.

We have found a security issue with the localbitcoins.com transaction feature, therefore we had to disable it for certain period.

If you had an ongoing transaction with funds, or if you had bitcoins in your localbitcoins.com wallet, you have to contact us so that we can send you the funds manually.

Easiest way is to contact us through your user account via this ad: <deleted>

If you contact us through that form with your user account, we know that it is you doing the contact.

If you have any questions, you can contact us at support@localbitcoins.com . We try to answer all questions.

We apologize sincerely for this issue to our customers for this issue.

Edit: the issue is fixed and the transaction service should be running again

Easywallet.org users - remember to back up your wallet address!

Several of the following things can happen:

- You lose your phone
- Your phone auto-upgrades itself and loses apps and bookmarks
- Your phone breaks

Therefore it is always important to make a backup of your easywallet.org wallet. You can find the wallet URL as a QR code from the main site if you scroll down. Just store the URL to couple of separate locations, and you should be backed up.

Additionally it is always a good idea to set up a Dead Mans Switch, just in case.

The feature can be also used to redeem private keys, and easywallet.org coupons.

The test videos:
iPod touch: 13,5 sec (unlock + tap + scan + confirm)
Android Samsung galaxy S3: 9 sec (tap + scan + confirm)



To activate the feature for your mobile: go to your easywallet.org page, scroll down and click "one-tap payment url". Bookmark this page, the icon will act as "one-tap" payment solution.

Dead Man's Switch with Easywallet.org

We have added a Dead Man's Switch feature to our easywallet.org . This is very useful feature for couple of applications:

  • Setting up "backup address" to your significant other, in case you lose your wallet URL in a way or other.
  • Making timed, anonymous transfers to different bitcoin addresses.
It is good idea to set up the Dead Man's switch just in case, because there isn't any fees if the feature doesn't activate.

Easywallet.org bug fixed! Incoming transactions working again.

Hi, there was a small bug today in easywallet.org for about 1.5 hours - incoming transactions were not properly processed. The problem is now fixed.

The following problems could be caused by this:

- Erronous balance change updates (the blue boxes)
- Erronous wallet history - one transaction showing as multiple

No actual erronous balances, double spending or any other serious bugs could be done using this bug.

Sorry for the issue.

LocalBitcoins Escrow service rebranded to "LocalBitcoins Transaction" or short "Transaction"

We have changed the name of the escrow feature to "LocalBitcoins Transaction" or just "Transaction" where the connection is obvious. We changed the name because it is not actually escrow service by the traditional definition, no disputes or resolution services.

Other terms: 


"Transaction verify code": this is generated for the buyer. When the seller shows this code to the buyer, buyer can be 100% that funds have been released. The buyer should check that the code shown by the seller matches the code shown by localbitcoins.com
"Transaction release code": the seller can release the escrow by sending this code to the number +16466994674 . This releases the funds to the buyer, and the seller should receive the verify code promptly, which he/she can show to the buyer.


The benefits of the service are:

- No internet connection needed - only one SMS-enabled phone required to make the transaction on the spot, or only one internet-connected laptop
- Quick process - the buyer does neet any devices, just memorize/write down the transaction verify code
- Allows the users to gain reputation via confirmed trades. If users use this service, we have a way to confirm that trade actually happened.

The LocalBitcoins Transaction service is not enforced in any way. You are free to create any kind of deal with the customer, use smartphone clients, laptops, whatever. We just recommend to use the transaction feature when the customer requests it - it should make the process much easier to the buyer.

Bitcoin cash exchangers already in 60 countries, almost 200 cities!

We are really happy with the global reach localbitcoins.com has achieved in the short time we have been developing the site. It is nice to see, that we have advertisers now from even countries such as Ghana, Malaysia, Venezuela and Cambodia, where Bitcoin could be really useful.

We made a simple statistics page, where we collect up-to-date statistics from localbitcoins.com:  https://localbitcoins.com/statistics

We are very excited with the positive feedback we have received for the site, and we are working on new features full time. This week our goal is to make the site translation-ready, so we can start making the site more useful for people from non-english countries as well.

LocalBitcoins Transactions via SMS - buy and sell bitcoins with cash, hassle-free and fast without internet connection

EDIT 16.8: Please note that we rebranded the service from "escrow" to "LocalBitcoins Transaction" or short "Transaction". This is because the service is not actually an escrow service. It is just a tool to make the exchange process easier.

Cash is a perfect method for buying and selling bitcoins. Paypal and credit cards have chargebacks, and are practically unusable for bitcoin transactions. Bank transfers are slow, and take away your privacy by enabling the bank to see all your transactions.

However there are lots of hurdles when trying to enable local bitcoin-to-cash transactions. What kind of devices you want to use, what kind of internet connection, how many confirmations should you wait, and so on. We try to remove all these hurdles with our SMS-based bitcoin escrow service. Only the seller needs sms-enabled phone, and the buyer doesn't need phone at all! So even internet connection isn't needed at the meeting point.

The process for the buyer is following:
  1. Make offer/receive offer
  2. Memorize or write down the escrow verify code
  3. Bring the cash to agreed location
  4. When seller shows you the escrow verify code, you can be sure that the funds have been transfered to you
For the seller the process is almost as easy:
  1. Receive offer/make offer
  2. Write down the escrow release code and phone number as a SMS message, don't send yet
  3. When the buyer brings you the cash, send the release code as SMS
  4. You should receive the verify code as a SMS, which you can show to the buyer
The SMS should work 99,99% of the time - we have two different backends, so that if one fails, we will use the other. Also we have enabled the SMS messages in 150 countries - you should be able to use this process practically anywhere in the world.

If there are some problems, you can always head to the nearest internet cafe, and check the situation online. However, we are pretty confident, that practically in all cases the SMS escrow process should work easily, and the transaction time could be less than a minute.

Also if the seller works for at example internet cafe, even the sms sending is not needed - you can just release the escrow online, and you will receive the code with you can prove that the escrow has been released.

Here are couple funny visualizations of the process (however note that since these, the process has been simplified):

Specify your price with min/max functions

Now it is even easier to minimize your risk when selling/buying bitcoins on localbitcoins.com, while still giving a competitive price. We added possibility for min/max -functions. For example, the following equation gives pretty competitive price when you want to sell in EUR:

max(max(mtgoxusd_high*USD_in_EUR, EUR_24h), intrsngeur_high)

Or if you want to buy in USD:

min(mtgoxusd_bid, USD_24h)

Not that these functions always require excatly two parameters.

We hope that with these advanced pricing functions people are more comfortable doing bitcoin OTC trades, with fixed prices.

Now you can connect your bitcoin-otc ratings to your localbitcoins.com profile

We just have made it possible to connect your bitcoin-otc account to your localbitcoins.com profile. Only the bitcoin address authentication support is currently enabled. However, it is trivial to add a bitcoinaddress to your bitcoin-otc profile.

If you already are authenticated on bitcoin-otc using bitcoin address, just go to your localbitcoins.com profile and follow the instructions. It should me less than 5 minute process, if you are using the standard bitcoin client.

If you are using only gpg authentication, you can easily enable bitcoin address based authentication with the following commands to the gribble bot:


;;changeaddress
<get the signature from your bitcoin client>
;;bcverify


After adding the bitcoin address, just go to your localbitcoins profile and follow the instructions. Essentially you sign the message provided by localbitcoins.com, and via that action you can prove that you are have the access to the specified bitcoin-otc profile.

Why to connect your bitcoin-otc profile to localbitcoins, then? You get all your bitcoin-otc feedback listed in your localbitcoins.com profile, which will add your credibility. Also you will get some nice badge to your listings in the future (we haven't yet implemented this).

Increasing Readership in the Bitcoin Sub-Reddit

One of the biggest online communities for Bitcoin enthusiasts is the r/bitcoin sub-reddit on reddit.com. I noticed in the spring that it was starting to gain readership at an increasing rate, so I decided to track the numbers.  Here's the result so far:


Unfortunately I didn't get any data points for the last month or so (except the most recent one), but the trend is still obvious. At this rate, readership will double by the end of 2012, demonstrating that there is indeed increasing interest in Bitcoin.

Bitcoin's Renaissance - The Stats

As Bitcoin has evidently found its second wind; let's take a look at the stats:

Number of daily transactions, excluding the top 100 addresses: record high.

Market cap: ~$80,000,000 USD: 10-month high.

Bitcoinary Launches Feature-Rich Peer to Peer Bitcoin Exchange

We are all quite familiar with the major Bitcoin exchanges; Mt.Gox, BTC-e, Intersango, VirWox, etc. For people looking for a more direct method of buying and selling Bitcoins, there are limited options, including bitcoin-otc, which can be very intimidating to the average person, and the Bitcointalk.org marketplace forum, an arguably risky place to trade Bitcoins.

Though the major exchanges support trade in nearly 20 different currencies, that represents less than 15% of the currencies being used worldwide, thus keeping Bitcoin out of the hands of the people who probably need it the most.

I don't know how many times I've heard the question asked, "can I buy Bitcoins with PayPal?" While yes, you could, unfortunately no one is going to sell you Bitcoins for PayPal unless you have developed a traceable and positive reputation in the community. Now, with Bitcoinary, it's very easy to do so.

Bitcoinary takes the credibility system from bitcoin-otc and gives it a web-based front-end with a facility for private messaging. People can now trade Bitcoin and build a history, all on one user-friendly site.

Solving the chicken-and-egg problem, users can link in their social credibility so buyers know who they're dealing with even if sellers don't yet have a trade history. Equally important, you can't create multiple Bitcoinary profiles using the same social proof, as once you attach your Facebook, Twitter, or mobile phone number, those connections can't be used again.

Bitcoinary is essentially eliminating the middleman, allowing people to become their own exchange. Quite simply, if you have a computer and access to a local currency, you can become a market maker for that currency. You can do it with gold, cash in an envelope, in person exchanges, rupees, dollars, anything you want. The site itself suggests the possibility of in-person international exchange for travelers, which could become an important niche for Bitcoin.

Bitcoin Exchange Opens in Colombia

On May 28th, a new Bitcoin exchange opened its doors, BitMarket Colombia.

BitMarket Colombia is owned and operated by Markus Döbele, a native of Germany. Having access to bank accounts in both countries and already using the European exchanges, Markus thought that Colombians should also have access to a similar Bitcoin market. As a result of the creation of his exchange, Bitcoins can now be exchanged for the Colombian Peso.

The site is hoping to receive coverage in local magazines and newspapers in order to grow its user base, however, in a country with 10% annual inflation, the potential market seems obvious. Markus believes Bitcoin could play an important role for Colombians as a means of preserving their wealth.

Anytime a new market gains access to Bitcoin, it's a pretty big deal. Hopefully we'll begin seeing Bitcoin penetrate other markets in the near future.

Enter the Dragon: BTCChina's Volume and Exchange Rate Suddenly Explode Higher

The Bitcoin community has been abuzz over the last 48 hours as trading activity on the only Chinese Bitcoin exchange, BTCChina, has gone stratospheric, with volume 700% above the norm and prices skyrocketing more than 10% higher than the Mt.Gox exchange rate.

Traders on the Chinese exchange are showing no signs of relenting, with 7698 BTC traded yesterday and 8495 BTC already traded today. The last trade was for 35.8 RMB or $5.64 USD, significantly greater than the $5.12 rate on Mt.Gox. With this activity, BTCChina has, at least for the moment, thrust itself into position as the second largest Bitcoin exchange.



Possibly related, earlier this month, Roger Ver (memorydealers.com) and Yifu Guo (BitSyncom) organized a Bitcoin meeting in China. With only 24 hours notice, over 30 people showed up to learn about and discuss applications for Bitcoin, including opening an exchange in Macau to facilitate the movement of currency to and from "China's Las Vegas."


Also coming out of Roger and Yifu's visit to China was a contract with a tablet manufacturer to produce a sub-$100 tablet running two Mali-400 processors and sporting a 1200x600 IPS screen. Taking a step toward realizing BitSyncom's Meshnet project, each tablet will run Bitcoin relay node and wallet software. The manufacturer, hearing about Bitcoin for the first time, considered loading all of his tablets with Bitcoin software (over two million per year), which could spawn others to do the same. Expect to see BitSyncom's tablet on the market by the end of the calendar year.

Is the activity on BTC China related to the development of these projects? Hard to say, but hopefully we'll find some answers in the coming days.

Bitcoin's Liquidity: A Third Look

Back in November 2011, I wrote about Bitcoin's liquidity, and how it had improved from six weeks prior. Let's take a look at how we're doing, six months since:

On October 16th, a $50,000 purchase would have moved the price from $3.40 to $3.92, a 15.3% increase. A sale of $50,000 worth of Bitcoins would have taken the price down to $3.03, or a 10.9% drop.



On November 27th, a $50,000 purchase of Bitcoins on Mt.Gox would have moved the price from $2.46 to $2.60, a 5.7% increase. A sale of $50,000 worth of Bitcoins would have taken the price down to $2.30, or a 6.5% drop.


So, how is it looking now?

The market is looking considerably more stable. Today, a $50,000 purchase would only move the price from $5.11 to $5.16, a 1% increase, and a sale of $50,000 would drop the price to $5.06, also a 1% move.



In the last seven months, the Bitcoin market has clearly matured significantly, making it increasingly stable and usable as a currency; something many merchants have been waiting for before deciding to accept Bitcoin. Hopefully this will translate into wider acceptance and growth of the economy.

Bitcoin's Hogwarts: San Francisco Tech Space "20Mission" to Open in August

Jered Kenna, formerly of TradeHill, and Jonathan Ryan Owens of RingCoin have teamed up to launch 20Mission, a huge 41-room tech space project in the heart of San Francisco.

The goal is to open 20Mission to tenants on the 1st of August. Finding tenants will apparently not be a problem, as the reservation list has grown quite long, with prospective tenants even stopping Jared on the street to get in on the action.


Kenna and Owens are hoping the space will produce a wide array of successful projects, most of which will be focused on Bitcoin-related businesses, though the space isn't being advertised as "Bitcoin-only." No doubt, having this much talent concentrated and living in a small space will streamline the development process and encourage the type of brain-storming that could produce exceptional ideas.

In this three-minute video, Jered Kenna takes us for a tour and explains the idea behind 20Mission, including who the building is geared toward, what the spaces will look like, and his crazy plans for the roof:

Bitcoinica's Founder to Cease All Involvement with Bitcoin

Hot on the heels of a major hack at Bitcoinica, Zhou Tong, the founder of Bitcoin's most successful Bitcoin project to date, has just announced that he will no longer involve himself in any Bitcoin-related projects:

"I, Zhou Tong... will discontinue all involvement in Bitcoin-related projects after the Bitcoinica incident has been fully resolved until further notice. I failed at one thing... that is generating value for the society. Bitcoinica did create a place for people to trade more efficiently and provide liquidity to the market. However, speculation is a zero-sum game (or negative-sum, strictly saying). I know there can be many justifications for Bitcoinica's value, but all of them are against my intuition and values."

In his announcement, he also revealed that Bitcoinica was actually sold in November of 2011, with the official handover happening in January of this year.

Not surprisingly, he will be moving on to pursue other projects:

"I have started working on another project (not Bitcoin-related) that is going to make a little difference on the Internet. So far I have achieved great progress and I'm pretty confident about this new venture."

Zhou Tong, a 17 year-old developer from Singapore, took the Bitcoin community by storm by creating the first advanced trading platform for Bitcoin. Several security incidents eventually pushed the site to the brink, the most recent being a $90,000 USD theft on May 11th. The site currently remains offline.

Upcoming GLBSE IPOs - A Review

ZETA-MINING 2012-05-13 @ 18:00:00 (GMT-4)

Yet another mining operation. You will likely receive predictable but small dividends if you invest in Zeta Mining (1 MH/share).

REBATE 2012-05-14 @ 23:18:35

This is definitely the most interesting of the upcoming offerings. Bitcoin Rebate is described as "a blend of penny auctions and arbitrage. Users bid on blocks of Bitcoin (powered by ZipConf) arbitrage opportunities against other players."

The concept of buying more Bitcoins for less Bitcoins might seem like a strange one, but it works if you understand the arbitrage going on behind the scenes. I suspect this will be a very popular and profitable site, at least until the arbitrage space gets a little more crowded and margins fall.

Half of the business is up for grabs (25,000 shares with each earning 1/50,000 of the fees collected by the service). Priced at 0.2 BTC each, this gives Bitcoin Rebate an initial valuation of $50,000 USD).

GOLD 2012-06-05 @ 18:00:00

This "gold bond" (not the stuff you put on your nuts) gives you the privilege of lending your BTC to the owner of the gold so that he can invest the money is his personal business. The gold is essentially acting as collateral, and bond holders will be paid a dividend of 0.73% of their investment on a weekly basis. Definitely an interesting way to secure a Bitcoin loan and a new way of using GLBSE.

SILVER 2012-06-05 @ 18:00:00

Same as the gold bond, but silver.

BITCOIN 2012-05-22 @ 22:00:00
PROPERTY 2012-06-08 @ 08:00:00
CASINO 2012-06-08 @ 18:18:00
INSURANCE 2012-06-18 @ 18:00:00
PENSION 2012-06-22 @ 18:00:00

These five are nothing more than someone reserving ticker names in the hopes that they can be sold off in the future.

Happy investing!

VirWox Breaks June 2011 Bubble Record for Volume Traded

Bitcoin's fourth largest exchange, VirWox, just posted a record for weekly volume traded of nearly 30 million Linden Dollars (SLL), or $115,000 USD. The previous record was set during the Bitcoin bubble of June 2011.


And in case you think this might be caused by inflation of the Second Life currency, the exchange rate has actually remained extremely stable, holding between 250 and 270 SLL/USD for the last three years. Notably, this exchange rate is managed through "printing" of the currency to keep up with demand.

The largest exchange, Mt.Gox, has seen its market share drop, with weekly volume continuing to dwindle and flirt with yearly lows. The loss of Bitcoinica, which conducted all of its trades through Mt.Gox, will no doubt add to Mt.Gox's woes in the coming weeks and months.

Bitcoinica Shutdown is Potentially Permanent

The latest from Zhou Tong in regards to yesterday's hack and the loss of over 18,000 Bitcoins:
- It's more serious than we thought. We need some additional time to come up with a compensation proposal.

- Likely we will either shut down the platform or re-develop entirely (which will take months instead of days).

- The preliminary decision: reimburse for the full amount, including margin balances and position P/L.

- The root cause of this problem is an email server compromise. The email server belongs to one of our team members.

- Reminder again: Please do not reuse your Bitcoinica passwords as the database server was compromised. Do not click any links in the email. All Bitcoinica announcements will be updated on Bitcoinica website when available.

Important Disclaimer: I'm not a partner of Bitcoinica LP after the corporate reorganisation. Therefore, I have no financial obligation in this matter as I'm only an employee of Bitcoinica LP responsible for daily operations (no shares, no voting). However, I'll do my best with the team to resolve this problem as quickly as possible and minimize the impact for the community. I appreciate your patience and understanding.

Sadly, these events are unfolding only 18 days after ownership of Bitcoinica was transferred to Intersango, who is now left holding the bag.

Meet Kronos.io: Ringcoin's Answer to Bitcoinica

As we continue to digest the news coming from Bitcoinica, another group of developers is working hard to level the playing field in the battle for the Bitcoin CFD space, which until now was monopolized by Singapore's boy-genius, Zhou Tong.

Jonathan Ryan Owens and his team from Ringcoin are fiercely putting together the final code for Kronos.io. Advertised as "Bitcoinica on steroids," Ringcoin will be leveraging their highly touted ZipConf platform to improve the Bitcoin trading experience.

Unlike Bitcoinica, Kronos will utilize the tech behind ZipConf to eliminate its hot-wallet risk, allowing for instant multi-market hedging.


With security concerns being the topic du jour, Owens seeks to reassure his future user base:

"Under the hood, ZipConf is what allows Bitcoins to be delivered instantly to remote exchanges, which is also a huge security bonus. Bitcoinica has persisted in having a zero sysadmin policy. Kronos is built by sysadmins, on top of software built by other sysadmins (ZipConf). Kronos uses SSH and SFTP to remain extra secure; I won't even have the keys!"

Planning to support three exchanges at launch (Mt.Gox, Bitstamp, and CrytpoXChange), Kronos will be faster and allow for even greater leverage than with Bitcoinica. Of course, greater leverage equates to greater risk, but Kronos promises a functioning stop loss, something Bitcoinica's users have been keen to have at their disposal.

In light of today's hack at Bitcoinica, Owens has lit a fire under his team. Originally expecting to launch in one to two weeks, the new target is three days.

Though the site might look familiar to Bitcoinica's users, that's only because it currently uses the Twitter bootstrap common to many sites. When Kronos is launched, expect to see a unique design unveiled, which Ringcoin claims will be extremely intuitive and user-friendly.

Alberto Armandi, the lead developer for the project, was quick to remind that it's what's under the hood that counts: Kronos is built on a node.js realtime price monitor developed over the last few months using jquery and ajax with a node.js backend. It's a tool that Armandi coded for his own site, BitcoinRebate.com, another interesting service scheduled to launch in the coming days.

For further information, you can contact Jonathan Ryan Owens at info@ringcoin.com. In the meantime, someone pass the methadone; this leveraged trading withdrawal is killing me!

Developing: Bitcoinica "Hacked" - Potentially 18,000 BTC ($90,000 USD) Stolen

Bitcoinica has been shutdown until further notice, following a theft of 18,000 BTC. News of the hack was posted this morning by Bitcoinica's founder, Zhou Tong:
"Today, we have discovered a suspicious Bitcoin transaction that doesn't seem to be initiated by any one of the company owners. Some of them are not online at the moment so this is not conclusive.

 Suspicious transaction:

{
"account" : "",
"address" : "182tGyiczhXSSCTciVujNRkkMw1zQxUVhp",
"category" : "send",
"amount" : -18547.66867623,

"time" : 1336738723
},

We have contacted Rackspace to suspend all our servers and lock down our accounts. All your trading and financial data is safe (as far as I know), apart from the Bitcoin loss. Thank you for your patience and understanding while we investigate this issue in detail."
And in a follow-up post:
"Our data is kept inact. Any order placed before the shutdown will still be valid. However, no order execution will happen (no zhoutonging either).
If the market moves significantly, we will come up with a proposal to compensate disadvantaged customers once the investigation is complete."
Bitcoinica was also the victim of a 43,000 BTC ($215,000 USD) heist back on March 1st.

It will be interesting to see how the market is affected by the inability of traders to take leveraged positions in either direction. Also, you should not surf to Bitcoinica.com, as the site has been redirected to a porn site.

Bit-Pay Processes Record-High Merchant Transaction of 3095 BTC (~15,000 USD)

Bitcoin's most successful payment processor, Bit-Pay has just set a new record for itself, processing a 15,000 USD transaction between a customer and a merchant in the United States. The purchase was completed in Bitcoins (3095 BTC), with Bit-Pay converting all or a portion of the transaction into US dollars for the merchant.

The merchant? Butterfly Labs, selling one of its 25 Giga Hash mini-rigs.

FarmVilleFeed.com (100,000+ Daily Impressions) to Run Bitcoin-Based Advertisements

I've heard a few people suggest that games like FarmVille would be the perfect match for Bitcoin.

Well, Zynga's not exactly ready to take that step, however, ladies and gentlemen of Bitcoin land, I am pleased to announce that the brains behind FarmVilleFeed.com is in the process of creating a specific page on his blog to promote Bitcoin.

He will also be accepting Bitcoin-based ads on his site, which will give Bitcoin entrepreneurs the chance to expose their sites to a blog which receives over 100,000 daily impressions.

Why accept Bitcoin-based ads? Simple: no more payment-processor middlemen to take a cut of your advertising revenue!

The Bitcoin Stock Market - Miners and Pirates, Oh My!

As of this morning, there are 8.9 million Bitcoins in circulation with a combined value of over $45 million USD. It isn't exactly a secret that a good portion of those Bitcoins are held by speculators and investors hoping to see the currency gain traction and their Bitcoins appreciate in value. All that to say, there is a heck of a lot of money sitting idle and not being put to work. At least, that was the case until recently.

Non-Bitcoiners may not be aware of this, but there is a substantial secondary market where Bitcoins are being used to kickstart (heh) various community driven projects, mostly, at this point, with a view to further developing the infrastructure that overlays and streamlines the Bitcoin economy.

The GLobal Bitcoin Stock Exchange (GLBSE) is the primary site through which most of these transactions are occurring. To give you an appreciation of the size of this market, over 5600 BTC ($28,000 USD) in securities were traded on the exchange in the last 24 hours, equal to about 1/6th of the 24 hour volume on Mt.Gox.

The top five securities by total volume traded, measured in Bitcoins, all represent mining operations, which shouldn't come as a big surprise to anyone.

(Edit: I spoke too quickly here. Three of the top five are mining operations, one is a bank, and one is a trading bot. Thanks to one of the readers for picking this up.)

The larger mining operations are always looking to acquire more hardware, and there's no better way to do that then to sell stock in your operation. Things get interesting when you look at the next five securities. Four of those five are "Pirate Pass Through" bonds, which I'll explain...

There's this "bank" see, run by a mysterious individual going by the name of "pirateat40" (pirate at 40) who has been soliciting Bitcoin deposits to finance an even more mysterious business of sorts. There are various theories floating around as to the nature of this business, most of which fall into one of two categories: one, a massive (by Bitcoin standards) Ponzi scheme where the interest on earlier deposits is paid using later deposits, or two, pirateat40 actually sells Bitcoins for cash to various entities who are looking to acquire substantial amounts of the currency without leaving a paper trail, as would happen if they used a conventional exchange.

Six months into the scheme, and not a single interest payment from the Bitcoin Savings & Trust bank has been missed, yet the interest rates are enormously lucrative for anyone willing to take the chance. For example, a 2000 BTC deposit (~$10,000 USD) will earn 7% interest per week!  You heard (read) me. If you were lucky enough to be one of the earlier account holders, you could be pulling in enough interest on a 2000 BTC deposit to cover a mortgage on a decent sized home. Unfortunately, pirateat40 is not always accepting new deposits (lending some support to the "not a Ponzi scheme" theorists), which leads us back to GLBSE and the "Pirate Pass Through" bonds, a means for anyone to get in on the Bitcoin Savings & Trust action.

A "cartel" of some of the more well-known members of the community has established a series of bonds that pay out 1.28 BTC per bond after four weeks. Each issue of bonds (PPT.A, PPT.B, PPT.C, etc) is auctioned off on GLBSE and typically sells for between 1.06 and 1.09 BTC per bond, giving investors a very respectable 15 to 20% ROI. The money raised from the bond sales is deposited into the Bitcoin Savings & Trust, where the bond backers earn substantially more interest (as explained above) than is paid out to the bond holders. Should the Bitcoin Savings & Trust default on their interest payments, the whole scheme would fail, and the bond holders would be paid out only a fraction (25%) of the bond value. For the moment, however, everything is holding together.

Not surprisingly, given the ingenuity of Bitcoiners and the ease with which Bitcoins enable financial transactions, an issue of "Anti-Pirate" bonds was created, sort of a credit default swap for anyone looking to hedge the risk of depositing with Bitcoin Savings & Trust. Interestingly, after a week, not a single Anti-Pirate Bond was sold, and in the words of the bond's backer, the sale was "a spectacular failure."

By the looks of things, pirateat40 has earned a lot of trust in the community. The question remains, however: what the heck is he doing with all those Bitcoins?

In the meantime, you might want to look at some of the other offerings on the GLBSE which range from companies like ZipConf (claiming to be able to pay a 6% dividend) to Satoshi's Daemon, a racehorse whereby the horse's winnings are distributed to the shareholders. And if you don't feel comfortable making your own investment decisions, there's always the "Gamma Bitcoin Fund," where you can have your investments managed for you.

Of course, if those don't sound exciting enough, you could always take a chance with the pirate...

ZipConf.com - Waiting for Confirmations About to Become A Thing of the Past


A consequence of Bitcoin's architecture has always been the risk, albeit tiny, of the zero confirmation double-spend.  As a result, most Bitcoin exchanges have made it a point of only accepting a deposit after the Bitcoin network has verified the transaction, with six confirmations being the accepted standard. Typically, wait times are on the order of an hour to complete a deposit to an exchange.

Addressing the problem, ZipConf.com is rolling out a service to eliminate this delay, thus making Bitcoin an even more efficient means of moving your money.


"ZipConf acts as clearing house to provide instant credit to its clients and partners while assuming the risk associated with zero confirmation transactions," says Jonathan Ryan Owens, ZipConf's founder.

Obvious potential customers include those interested in conducting arbitrage trading between exchanges, where previously the hour-long delays associated with moving Bitcoins added a potentially expensive obstacle to the process. Consequently, you can anticipate a leveling in Bitcoin valuations across exchanges once ZipConf is operational.

After months of testing, Jonathan Ryan Owens says the API used to integrate his service with ZipConf's partners is ready to go. Once a site is integrated with ZipConf, it can allow its users to withdraw their funds instantly to a Bitcoin exchange, making the conversion of Bitcoins to fiat currency near-instantaneous. While sites like BitInstant have done a fantastic job in facilitating the conversion of fiat to Bitcoin, this is the first time that the Bitcoin to fiat path has been streamlined.

In developing ZipConf, great effort has gone into monitoring the Bitcoin network to log invalid transaction attempts and orphan transactions, ensuring the service has a complete picture of what's going on with the Bitcoin network at any given time. They've even been attempting double spends through various means to ensure they know what to look for when their service is operating.

Explains Owens, "The way we've built our platform is with two things in mind: security, and scalability. If we have to scale to supporting larger volume, we can do that with very little effort, as we've built the system in such a way (our monthly IT cost for multiple VPS alone is over $200) that we're ready to expand rapidly, and as such we'll be partnering and providing integration information (API documentation, support) to as many partners as possible, as quickly as possible."

Catering to traders and other users that require speed in their transactions, fees will start at 0.75% for individuals with the intent of reducing them as volume increases. "We hope to be able to reduce fees as low as 0.4% in the near future, once the volume is there," says Owens.

A key element to ZipConf's strategy is to ensure miners rapidly accept and propagate its transactions.  Of course, a little incentive never hurts, therefore ZipConf will be paying significantly higher than typical transaction fees to miners that include its transactions in their blocks.  For example, a 100 BTC transaction will net a pool or miner 0.07 BTC (or $0.35 at today's exchange rate), significantly higher than the 0.0005 BTC enforced by the standard client.

ZipConf's profits will go toward other Bitcoin projects which are currently under development. "We haven't put much out there into Bitcoin," adds Owens, "but we have been spending a lot of time tooling up to be able to rapidly develop and introduce services from here on out, so keep your eyes open - this is just the first of hopefully many useful services we'll be putting out."

The site is currently in private beta with intentions to step up to a public beta come Friday, May 4th.

BitInstant Transfers $1.1 Million in April as the Bitcoin Economy Takes Off

Charlie Shrem, CEO of BitInstant, today reported that his service transferred $1.1 million in USD and Bitcoins in the month of April, representing 120% growth over February and 340% growth over December. BitInstant is a popular service primarily used to rapidly move US dollars into and between the Bitcoin exchanges.

His report comes hot on the heels of widespread indicators of exponential growth throughout the Bitcoin economy. Loan services, stock exchanges, merchants, and Bitcoin gambling sites are all demonstrating significant growth for the first quarter of 2012.


Seemingly sensing the momentum, Bitcoin miners are also stepping up their game, with the network experiencing a rare (record?) spike to 18 Thash/s just yesterday (image courtesy of http://bitcoin.sipa.be/).  Though the spike could be merely a representation of some miners getting lucky, the overall trend is clearly to the upside after last fall's difficulty drop.


Network transaction graphs are also pointing to a rapid increase in the number of Bitcoins moved in a given day (graph not currently available but will be posted when blockchain.info comes back online).

Finally, though I'd love to get philosophical about the reasons for Bitcoin's growth, at the end of the day, it might just be the porn.  =)

We'll have to keep a close eye on whether this is just a blip or a sign of a prosperous future for our fledgling currency - if I had to guess, I would say it's the latter.

Bitcoin Horse to Run First Race on May 2nd

Bitcoin users are a creative bunch, and rightly so, given they're using the most versatile currency ever created.

And it doesn't get more creative than this!

Using the Bitcoin Stock Exchange, forum member TTBit has sold enough "Bitcoin Interest Rights" to train a horse by the name of "Satoshi's Daemon" (ticker symbol SATOSHISDAEMON.HORSE on GLBSE).

The Bitcoin-backed bronco is scheduled to run on Wednesday at Evangeline Downs in Louisiana.  With $8700 for first place, the international consortium backing the horse could expect to see a nice dividend payout.

Try doing that with PayPal, son!

Edit: Satoshi's Daemon finished in last place. =(
