Title: CoinJar - Australia's first VC-backed Bitcoin startup
Post by: zhoutong on June 13, 2013, 09:47:17 AM
Hi Bitcointalk,

I'm Ryan Zhou (aka zhoutong). I recently joined a Melbourne-based Bitcoin startup with two other co-founders Asher (Australian economist and business writer) and Jerrold (Enterprise software engineer with 10 years of experience). I think it's great to give bitcointalk forum members a quick update and overview about what we are doing and how we are improving the Bitcoin economy.

CoinJar: https://coinjar.io/

"CoinJar is a Melbourne-based startup bridging the divide between digital currency and the dollars in your wallet. Bitcoin was naturally the best place to start, being the world's leading digital currency. Founded in 2013, we quickly caught the eye of early start-up investor AngelCube who have generously provided us seed funding and mentorship."

Currently we offer three Bitcoin services:

CoinJar

CoinJar is a hosted Bitcoin wallet ("hosted" means "store just enough for transactional purposes and NEVER use it for savings") that integrates well with other parts of the platform. To be honest, there's nothing too much we can innovate on Bitcoin hosted wallets because they are so simple. However, we aim to deliver the best possible user experience. Aside from the web, we are also building an iPhone app for CoinJar wallet with great mobile experience (finally).

Please note that CoinJar wallet is a full-reserve platform with automated sweep to cold storage and we will never use customer funds for our business expenses. That said, be aware with any hosted wallet service. We recommend against our users to use CoinJar for Bitcoin savings. Always use cold storage!

CoinJar Checkout

CoinJar Checkout is the best Bitcoin merchant solution. We provide a PayPal-compatible API (in addition to our standard RESTful API) to help any online merchant to integrate. On top of that, industry-standard features: 1% fee, daily settlement in local currency (Australia only for now) and exchange rate guaranteed for 15 minutes.

CoinJar Filler

This is our killer app. Most other Australian Bitcoin buying sites charge excessive fees (usually 8-10%) and we really HATE to see that. A high fee will severely limit adoption and result in bad consumer confidence. Even though Australia has a well-developed financial system, when it comes to anything related retail foreign exchange services, it's a straight-up nightmare (even major banks in Australia all charge ridiculous ~4% spread each side for AUD/USD TT rate). As a full-service Bitcoin startup, we have sufficient liquidity available from our merchant solution and arrangements with institutional forex brokers (who give us wholesale rates), we want to pass on the savings to consumers by charging a just 2% flat fee.

Both Checkout and Filler are Australia-only for now, but we are definitely interested in expanding overseas. (Contact us at info@coinjar.io if you're interested in partnerships. Please reference this post when you contact us.)

We also have a by-product:

Melbourne Bitcoin Euthusiasts meetup! (http://www.meetup.com/Melbourne-Bitcoin/)

I attended yesterday's first meet-up session with 17 other Bitcoiners. It was really a great event and CoinJar plans to do it approximately every two months. So please join the meetup group if you're located in Melbourne!

Let me know if you have any feedback with our service offerings. Feel free to comment in the forum post.

We are in the process of setting up a company bitcointalk account.

Client sided encryption please.

It's not encrypted in the client - the user doesn't control the private keys. That can be ultra transparent and not affect the user experience.

Your reset password function is also broken FYI: "1 error prohibited this user from being saved: Reset password token can't be blank"

Seems pretty good and I may use it but why not a .com or .com.au or something?

It's a fair comment. We had two options to choose from, either Blockchain-style wallet or Coinbase-style wallet. We decided to go with the latter because we need full control over the whole user experience. This decision should make a lot of sense to many people if you have seen the one-click payment button on CoinJar Checkout page.

CoinJar also has full APIs available for programmatic access to wallet. Self-managed private keys will greatly increase the complexity.

Also, managed wallet solution makes instant payment between CoinJar users possible without paying network fees. This instant payment is used by our own platform components. For example, when you buy Bitcoin from Filler, the Filler application will actually send money from its own CoinJar account to yours. We also heavily utilize the internal payment system to do our accounting and hedging.

Many new Bitcoiners are not familiar with the concept of private keys. As long as they don't hold a large amount of deposit with a hosted wallet, we shouldn't close the door for them. I'm thinking of a system to notify users when their balance cross a certain threshold, to give them tips and guides on how to set up a secure Bitcoin storage themselves. Do you think that will help?

Again, we are only interested in facilitate the transactions as there are no interest to be earned from Bitcoin anyway.

coinjar.com is already taken by a domain squatter.

coinjar.com.au is registered by us, but as we may want to use it globally, it looks a bit inappropriate. That said, we will consider making coinjar.com.au a localised version of the platform, as most features are useful in Australia anyway.

.IO is a really popular "gccTLD" right now, and many startups (such as GitHub and App.io) started using it. We think it's cool.

Not really. There's plenty of technical ways where you can allow the user to store the private key, and provide a one click checkout experience - for example, storing a encrypted (so only CoinJar can access it) paraphrase in a cookie. Giving a user access to their private keys is important as anything that relies on Bitcoin address will not work.

I saw that! (Pretty sleek UI btw) - that is actually possible while letting a user control their own private key too. The same way where you can make a multi currency wallet.

Sure, it would take some time to develop, but seeing as what happened with Bitcoinica..

Bitcoin is designed[1] where each user has access to their own private keys. Going against this will mean that when you get hacked, it's bankruptcy for you, instead of a "Oops, we'll have service restored soon". Sites get hacked all the time, especially when there a multiple vectors. Take a look at Sony, Facebook, Microsoft, Apple, Google. Luckily, they don't store the most liquid form of money :)

1: "A generation ago, multi-user time-sharing computer systems had a similar problem.
Before strong encryption, users had to rely on password protection to secure their
files, placing trust in the system administrator to keep their information private.
Privacy could always be overridden by the admin based on his judgment call weighing the
principle of privacy against other concerns, or at the behest of his superiors. Then
strong encryption became available to the masses, and trust was no longer required.
Data could be secured in a way that was physically impossible for others to access, no
matter for what reason, no matter how good the excuse, no matter what.
Its time we had the same thing for money. With e-currency based on cryptographic
proof, without the need to trust a third party middleman, money can be secure and
transactions effortless."

Yes it is. We have to do that due to the reasons above. I believe that there are plenty of good solutions available for client-side wallets, and personally I use Blockchain.info wallet service (but infrequently).

After all, for a security paranoid, the only no-trust solution is to use the official Bitcoin client and only update after reviewing the source code. We *may* be able to contribute to reduce the "trust bar" for Bitcoin services in the future, but that's not our focus right now.

Post by: 🏰 TradeFortress 🏰 on June 13, 2013, 10:14:54 AM
What if you get a court order to freeze/seize someone's account? That's simply not possible with Blockchain.info-styled wallets. With growing crackdown on "money laundering" and how the blockchain is 100% public, imagine some rubber stamped warrants for Bitcoins with known silk road taint :(

Anyways, you guys have made the decision to go with a shared wallet. Best of luck, I'm just expressing the concerns and problems with shared wallets in general.

Also, what are your fees for Bitcoin payments?

Thanks for your feedback and I really appreciate it. As a huge believer in Bitcoin and Libertarianism, I share the philosophy that ultimately every user should be able to gain absolute liberty over his money (i.e. medium of exchange and store of value), both technically and legally.

We will definitely think about the solutions you proposed. Maybe we can implement a CoinJar "Advanced" mode for non-shared wallet and limited-trust private key management (client-side encryption).

This is a valid concern. I like your reasoning and feedback. Even though we have made the decision for our version 1, we are still innovating every single day! (That's how VC-backed startup should work right?)

If you come to Melbourne sometime, feel free to come to our office to say hello. We are currently working in Inspire9 (http://inspire9.com).

EDIT: We don't charge any fees for CoinJar wallet service. We absorb all Bitcoin transaction fees. Our business mode is to make money from Filler and Checkout services.

Also I just arrived in Melbourne today and - it seems - JUST missed the bitcoin meetup :(

Thanks!

2-factor is in our planned feature list. We spent a lot of time on the infrastructure itself, but features like this are easy to add. If you have more ideas after trying out our services, please give us feedback at info@coinjar.io.

If you haven't, you can join the meetup group to subscribe to our updates.

Please make sure the code is well designed this time around. I ended up looking through the bitcoinica code for a client couple months ago. Let's just say, the software engineering was a little inadequate for a site grossing $1m. In any case, good luck!

Very interested in the Checkout feature and paypal compatible API, but why does that need to be restricted to Australia only.

I work with several online merchants that would add bitcoin as a method of payment to their sites if there was an easy way to integrate with what they are already using and this sounds like it might make that possible.

We didn't restrict to Australia only. Our system supports over 10 different currencies and everything was designed to be global. However, we can only do daily settlement to Australian bank accounts at the moment as we don't have bank accounts elsewhere. International wire transfer will cost $20-$25 per transaction for us. We are happy to take any international client onboard if he is willing accept the wire fees.

EDIT: We will definitely expand into more countries in the future. At this moment we can't overcome the geographical and legal limitation to support international clients globally. We're also interested in partnerships (Email us).

You guys claim to be instant, but I have been told by friends that have tried to use this service, that it is not instant. 

One of my friends deposited money on a Friday and could not get bitcoins from you guys until Monday!!  (you guys really should not be claiming instant bitcoins - It's false advertising)


I also really don't like the fact that we have to put so much personal information into your website before being able to buy coins, that is why people hate using Mt Gox.

None of the other bitcoin sellers in Australia demand any personal info...

Yeah man, I am really concerned after reading about the founder of this website.
I read on many threads that he has scammed many people with previous websites...
[search Zhoutong]

Some have actually coined the term: "getting Zhoutonged" meaning to get ripped off or raped... "to loose all your BTC"
https://bitcointalk.org/index.php?topic=63831.0

I have always been a big believer in "if it sounds too good to be true, it usually isn't"... 2% fee just doesn't sound like it is a sustainable business model.  All the other websites charge much higher fees, SpendBitcoin is the highest and his website explains very well why the fees are so high in Australia.

To be fair, I have friends who have used this new CoinJar service and got their Bitcoins fine (although not instantly as claimed)...  However, that is how scams usually work, build everyone's trust and then scam hard for heaps of money.

The fact that all the money and bitcoins in your CoinJar account are held in their possession is very scarey.

Interbank deposits usually take 1 business day. If you want the deposits to clear as soon as possible, please transfer from a CBA account or before your bank's cut-off time.

Bitcoin purchases are instant. Once you have the deposit in your account, you can buy Bitcoin and get any number of instant exchange rate quotes. If you confirm the quotes within 30 seconds, they are locked in and the Bitcoins are automatically sent to your wallet.

The only personal information we collect includes your name, email and phone number. And we accept cash deposit.

Unfortunately, due to huge spikes in demand, we had to fall back to manual processing to deliver the Bitcoin purchases. This usually takes no more than a few hours and we have arranged a source to continuously supply Bitcoin in large amounts. We're already doing something like $5k a day within 2 weeks of launch. It's expected that instances like this will be very infrequent in the future.

Thanks for your support BTW. :-)

The fact that all the money and bitcoins in your CoinJar account are held in their possession is very scarey.

 

CoinJar is backed by Melbourne-based startup accelerator AngelCube (can be verified from their press release). Please be assured that VCs do due diligence much more carefully and responsibly than a few random forum members.

You're under no obligation to use CoinJar Filler or keep your Bitcoins with CoinJar. We discourage our users from saving excessive amount in their CoinJar Bitcoin wallet (and any hosted wallet in general). There's nothing scary about it. We want to facilitate instant transfers and innovative use cases of Bitcoin, and we made the decision that we need to hold the private keys.

CoinJar's business model is to make money from Bitcoin-fiat transactions, mainly from our Filler and Checkout services. 2% is very sustainable because we have access to wholesale foreign exchange rates (1-2 pips vs 300-400 pips by Big 4). We have been gross profit positive since the launch of Filler and our investors are quite happy with our progress.

A key thing to remember is that CoinJar has a long term vision that prevents us from taking excessive short-term profits. Instead of asking whether 2% is sustainable for CoinJar, you probably want to ask yourself whether 10% fee is sustainable for Bitcoin's growth in Australia. CoinJar is not simply a place for you buy Bitcoins in Australia. It represents our vision to bring innovation to Bitcoin and potentially the financial services industry. We are keen to solve problems for Bitcoiners, and buying Bitcoin is just one of them.

It'll be great if you can spend some time to learn more about our products at https://coinjar.io. If you come to Melbourne, you're welcome to come to our office or join a meetup organized by us as well. Our business is tied to the broader market (that is Bitcoin) and it's in our every incentive to grow with the Bitcoin economy and we will never work against this principle.

Hi, love the process and the fees, a bit slow with all the manual inputs ect. but this time when I have purchased BTC it says "We will send you ฿ 1.0653 within 24 hours."

the other times I have bought BTC it has been instant (after the bank transfer)

I will use in the future, and I hope you guys introduce a withdrawal(AUD) system at some point too  :)

Care to point out some hints?

Do you have evidence to suggest depositing from a clients bank account to another bank account used by a service like this is a problem? Or just posts from people like bitinnovate and spendbitcoins saying that they are discontinuing parts of their business so you have assumed this is due to client bank transfers?

coinjar is the next attempt of zhou tong in stealing your coins like bitcoinica

HE WAS RESPONSIBLE for the bitcoinica hack.. guilty as pirate.

don't buy bitcoins from him. I suggest btcquick or mtgox

Transfer money, get Bitcoin and immediately transfer out of CoinJar wallet. - Suggested workflow if you just want to buy Bitcoin and not spend it with CoinJar Checkout merchants.

Keeping large amounts of coins in CoinJar is discouraged. We don't get interest from the deposits.

You are now attacking the messenger. This is an ad hominem attack. I can clearly see how you were able to manipulate everyone into giving your coins for Bitcoinica for you to run away, with your professional fraudster skills.

I don't know what's an "ad hominem attack" (never studied psychology). I was just telling the truth. Everyone knows how to tell the truth. It's the easiest thing to do.

I'm happily developing products that make the world a little bit better. I enjoy what I'm doing - building stuff. Defrauding people will be obviously downgrading my life. Who wants that?

+1 to coinjar, really quick processing and low fees compared to others.

Only had one issue which was about a week ago with the manual transfer thing, but that was sorted out pretty quickly.

Do you accept cash trades at your office? It'd be really handy if you did.

Hi, Jerrold here from CoinJar. 

Just thought I'd add another voice to the conversation.  Kelsey, we've done a lot of background work on the banking system here in Australia before pursuing CoinJar, though we're very interested here to hear why you think direct credit is a bad way to do a bitcoin business in Australia.  If you'd like to discuss on the forum we're more than happy to hear your thoughts.  Consequently I'm also happy to discuss privately via email, which you can reach at my first name, at coinjar dot io.

As for zhoutong being on our team, both us and our investors are more than happy to have him on board.  We are a public and open company, and all information about us and our team can be found on our website.  We are not hiding anything.

Thanks cooldude123, we're still growing and we try our best to make everything right by our customers.

Unfortunately we won't be accepting cash trades at our offices.  Just from a security point of view, having a large number of people coming in and out of our offices, and also having cash lying around, we're just not at that size where we can guarantee safety.

Hi coinjar & Co,

Firstly, congratulations on launching a service which many in Australia will no doubt use. I do have one question though, you specify there's only 2% on the current spot price. For Australian customers does this include the GST element of 10%? If it does and given that once your revenue exceeds $75K you would be required to charge GST how is charging 2% on current spot price sustainable?

Thanks,

Stuart

Without a specific ruling from the ATO, we consider Bitcoin input-taxed supply, just like shares, bonds, derivatives, foreign currencies and precious metals. That means you have to pay GST for goods and services when you make purchases using Bitcoin.

The 2% fee itself already includes GST, because we charge 2% for the service we provide, and we will absorb it for now. (We may increase the fee to 2.2% if our profit is affected by GST, but there's no immediate plan.) Currently for CoinJar Checkout merchants, we give them access to a paper trail of GST paid, so they can easily claim GST credits if they are eligible.

(We are still in the process of GST registration, but the registration will be backdated to our incorporation date.)

Ok, and further to this since you're targeting the use of a tax ruling associated with financial services and intend to onsell them to end users (essentially acting a currency exchange) does this mean coinjar has an Australian Financial Services license and conversely is coinjar registered with AUSTRAC to ensure money laundering regulations are adhered to?

Seems too good to be true. Unless they have a clever new way to do verification they will suffer the fate of Bitpiggy (https://bitcointalk.org/index.php?topic=82045.msg920816#msg920816). Also they are exposed yet trying to play the regulatory gray area as to whether Bitcoin is a financial product or not.

Yeah, wonder how many reversed transactions they'll absorb before things change?  Even bitinnovate, that only accepted over-the-counter cash deposits, closed their doors....

They do have a progressive limit raising system where your limit goes up for each successful transaction, and a 7 day hold on the first transaction (which is limited to $100). This will help protect them from casual scamming.

The fact that they claim their product is taxed as a financial product but they're not registered to deal in financial products is another worry. Some people are bothered by the fact Mr. Zhou is a principal. I wasn't on the scene then but apparently he has a controversial history with his previous ventures. Another pink flag is the very low spread they charge. AFAIK it is far tighter than any competitor in the Australian market which makes you wonder, why? A grocer undercuts his competitor by 5c, not a dollar. Businesses with extraordinary prices often have non-business motives, such as scamming or money laundering.

That makes good sense.  Protection from casual scammers is relatively easy, it's the dedicated scammers you have to be careful of.

The fact that they claim their product is taxed as a financial product but they're not registered to deal in financial products is another worry.

Not with you on that one.  Calling something "X" for tax purposes is not the same as saying something is "X".

Some people are bothered by the fact Mr. Zhou is a principal. I wasn't on the scene then but apparently he has a controversial history with his previous ventures.

Dunno about anyone else, but I think keeping any more than a couple of coins on any exchange is risky.  Move them home, move them offline.

A grocer undercuts his competitor by 5c, not a dollar. Businesses with extraordinary prices often have non-business motives, such as scamming or money laundering.

Maybe they recognise that Aussie exchanges are gouging the hell out of us locals, and want to become the Australian bitcoin exchange (they've said as much).  Maybe they are hoping that by becoming internationally competitive, not just locally competitive, they can increase the size of the market?  Makes some sense to me.

We really don't have further information at this point. Yesterday all of our directors received notice from CBA that our personal accounts will be closed, but today when I called back again they said that was just a "current decision" and investigation was still in progress.

All sell orders are still stalled because we can't access client funds. There's not a single cent available under CoinJar Pty Ltd as we do not keep company cash. (But our all our Bitcoin are safe and we are still accepting buy orders as normal.)

I often go to sell my btc and forget instantly how much I currently have so I have to go back to the coinjar wallet and double check (about 5 times because of my memory).
Also when selling BTC it would be good to place orders, as I am often refreshing to get that 1$ extra when the price is fluctuating.

Jerrold decided to go back to his previous job because he wasn't really comfortable with startup life (12+ hours a day with no salary). But now Asher and I are very proactively bringing new guys on board, and we are planning to raise another seed round in the US.

Done! We have deployed the feature just now. You can choose to place buy or sell orders in both AUD and BTC. In most cases you should get the exact amount, but fluctuations can also happen in which case you can always cancel and create the order again. (This is a tricky feature to implement because Filler and Checkout platforms are entirely independent and they don't trust each other.) Thanks!

Personally I don't find the new implementation very helpful.

It'd be nice to be able to figure out the conversion rate without clicking the 'request quote' button. On other websites I am able to input BTC or AUD and immediately find out what I am going to be purchasing and for how much before clicking any submit buttons or making any actual deposits.

Quote
I'm getting an error "Global maximum reached" when selling bitcoin.
Modified on: Thu, Sep 5, 2013 at 6:54 PM

Looks like today's been a popular day for selling bitcoin. CoinJar has reached its limit of allocated bitcoin sell orders for today ($20,000 as of 28/8/2013). Try checking back in 6-12 hours.

I have replied to the support ticket, but will clarify here again just in case.

The actual quote for the transaction was correct and since you paid for it, we will send you the exact amount of AUD that you requested. However there was a presentation error in Filler because the exchange rate requote was not updated by the Filler system. CoinJar Filler is showing a larger BTC amount than what you have actually paid, and hence the exchange rate is much lower than actual (which is about 131.06).

Please also check your Bitcoin transaction history to see that you have paid the correct amount.

We are working on an update to address this issue. Requotes have been very rare but we agree that it's important to handle these situations smoothly. Thanks!

FYI, CoinJar Filler uses CoinJar Checkout to process sell orders (we use our own APIs to build the thing).

CoinJar now requires customers to be identified in order to use bank transfers to make deposits. However, cash deposits will still be available for all customers regardless of identification process. Identification is secure and optional.

Well thanks to mtgox's inability to do cashouts and btc-e having bitcoind offline for over 24 hours I finally decided to give coinjar.io a whirl.

I have to make the following statements:

  • I do have reservations about zhoutong, but the PR team behind coinjar.io have been great at engaging the community directly without side stepping any questions, they have also gone to above reasonable lengths to ensure they are easy to contact.
  • For someone living in AU, it does seem to be an extremely convenient cash out method
  • The rates are good to fair.
  • Im unfamiliar with their coin hosting service, but it seems to work well.
  • Trust for the site can be limited to whatever you feel comfortable depositing, I suggest doing regular increments as opposed to huge dumps.
  • The UI is clean, but it needs a touch more work. That being said, after 1-2 transactions its very easy to find your way around.
  • 3 Test cashouts later with a 4th just started and I have to say, the transfer time for me as a bankwest customer is 1-2 business days, very convenient

So, consider me your grumpiest most cynical sceptic that still likes to think of himself as "reasonable" ......Im impressed. 
Keep up the great work and I shall continue to use this nice service in bigger increments as my trust builds.

CoinJar is a participant of the Direct Entry system through our bank NAB. We only clear our books once every business day because otherwise it would make no difference in processing time. In most situations proceeds from Bitcoin sell orders should be received by the end of next business day.

I can see that your payment has been released.

ok been using coinjar for a while now, pretty good, nice interface, though a tad confusing, buy bitcoins/sell bicoins would be easier inmho that filler, and buy and sell nested under that

noticed

[1] CBA fell off, exactly what happened, I could not see the full story ITT
[2] So NAB now?
[3] Read TF's comments, would like a private key option....
[4] The rates are good 2% but even with PIP points at 2, not sure how you do it....I mean where are you buying from?
[5] Since the engineer left, who is doing the codebase? It looks like a lift from coinbase, but still alooot of work to keep it all running and mod it to Oz banks, do you hire people in?

I admire your efforts to date...!

[1] CBA closed all our business accounts and all directors' personal accounts without prior notice. We are still waiting for their final bank cheque and account closing statements.
[2] The NAB transition was very smooth and successful. We did not have any interruption in this business. Customers are now able to make cash deposits at any NAB branch, or use internet banking transfer. In the future, we will introduce an even easier and faster way to deposit funds.
[3] Do you mean self-managed private keys? At this stage it's not in our plan, because we recommend our customers to not keep an excessive amount of Bitcoin in CoinJar (or any other web wallet). However we will work on more security features to help our users manage their Bitcoin wallets.
[4] CoinJar enjoys a substantial advantage in terms of economies of scale. We have traded over A$1.5 million to date (though the company is only 4.5 months old) and we have access to much better FX rates than retail customers. We take both buy and sell orders and the excess exposure will be hedged in overseas Bitcoin exchanges.
[5] I have always been working on product development at CoinJar. The handover was perfectly smooth and we are still introducing new features every week.

Thanks for your support!

Finally, the wait is over. We just launched CoinJar for iPhone, the best and most beautiful Bitcoin wallet designed for iOS devices.

You can now use your iPhone to easily manage your Bitcoin wallet on the go, and quickly send/receive payments using the Bitcoin network. As a bonus, you can access to CoinJar Fair Rate™ right from your smartphone and even do simple calculations.

This is just version 1.0, so there might be some minor issues. We are collecting user feedback and suggestions. Please contact us at feedback@coinjar.com or visit https://support.coinjar.com if you want to share your thoughts or need help. A new version of this app will be available in the next few weeks.

Download it for free from the App Store: https://itunes.apple.com/au/app/coinjar-for-iphone/id725209873?mt=8 (https://itunes.apple.com/au/app/coinjar-for-iphone/id725209873?mt=8)

Note to 2FA users: You cannot sign in to the iPhone app when 2FA is enabled (because 2FA support wasn't built into the client). The workaround for now is to disable 2FA from CoinJar temporarily, sign in, and re-enable it again. The token credentials will be securely stored in your device keychain until you sign out. CoinJar for iPhone doesn't remember your password, so even if you change your email/password on the website, the mobile client will still be linked to your account.

We had some issues with NAB's system recently and the bank wasn't able to report intraday payments to us in real-time due to the huge volume we have been doing lately. CoinJar is processing over $2 million per month and we are constantly looking for more scalable ways to handle our banking.

The only problem I've had with coinjar is slow deposits.  A friend had a problem with a slow order fill (all day) during the crash earlier in the week.

I use bitpiggy as well as coinjar.

I have personally been using Coinjar to buy and sell bitcoins for the last 6 months. I dont use is as an online wallet, and if you do you should only keep a small amount on it.
That being said, buying and selling on coinjar is very easy, and I have never waited more than 48 hours for a deposit to arrive from a sale, or for my money to be credited to my coinjar.
As soon as you have bought BTC move them to an offline wallet. Simple.

Yes. Not only were I involved in Bitcoinica, but on the same day Bitcoinica was hacked for $40,000 goxusd codes, someone exchanged $40,000 worth of bitcoins, with the account stevejobs807@gmail.com, to try and launder the funds.

MtGox has said that stevejobs807@gmail.com's first account action back in 2011 was to redeem a Gox BTC code generated by Zhou Tong.

Erik Voorhees, a trusted member of the community says that Zhou Tong has emailed from stevejobs807@gmail.com before.

a day later, Zhou Tong on his main email sold $40,000 worth of BTC... he says it is for a "friend".

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

* On Friday, July 13 I was notified by MtGox that somebody had gain unauthorized access to Bitcoinica's MtGox account. I was also notified that most of the redeemable codes used in the heist were exchanged through AurumXchange on July 12.
* At the time I was on an extended weekend vacation with very limited internet access. I immediately notified Mark Karpeles at MtGox as well as Charlie Shrem at Bitinstant that I would take a closer examination of the situation on Tuesday upon my return.
* Upon closer examination of our database on Tuesday, I discovered that the hacker had indeed exchanged the MtGox coupons to Liberty Reserve through our instant exchange facility. The hacker had also exchanged Liberty Reserve back to MtGox presumably in an effort to conceal and/or "launder" the funds.
* Over all, the hacker exchanged a total of $61,875 USD from MtGox to Liberty Reserve, and a total of $17,500 Liberty Reserve to MtGox, for a grand total of $44,375 MtGox to Liberty Reserve. After our fees, this number amounts to approximately $40,000 USD.
* These orders were placed on our systems between 2012-07-12 11:46:48 and 2012-07-12 19:41:27 UTC.
* The IP addresses used by the hacker belong to TOR exit nodes to my understanding, and are as follows:

31.172.30.1
31.172.30.2
31.172.30.4
77.247.181.165
146.164.91.248
78.108.63.44

* The Liberty Reserve account used by the hacker is U9236056.
* The email address used by the hacker was stevejobs807@gmail.com.
* To my surprise, upon further examination of our order system, I found an order from Zhou Tong to sell Liberty Reserve to us for the amount of USD 40,000, requesting a wire to his bank account in Singapore. The amount for the order closely matches the total USD exchanged through us (after fees) using the MtGox USD codes stolen from the Bitcoinica account.
* This order was placed the next day the hacking attempts occurred. In addition, it should be noted that Zhou Tong has never dealt with us before as an exchange customer.
* This information was immediately sent to our two biggest trusted business partners: MtGox and Bitinstant in an effort to join forces to further investigate this situation.
* Mark Karpeles indicated that there was an account opened at MtGox using the email stevejobs807@gmail.com sometime in 2011.
* Mark replied stating that there was activity on this account, that the account was opened using an IP address belonging to Microsoft Singapore, that Zhou Tong was known to have worked for said company at said location, that the email stevejobs807@gmail.com have been verified, and that ALL activity on this account is linked to the MtGox account belonging to Zhou Tong.
* Mark has also indicated that the very first operation on the MtGox account opened with email stevejobs807@gmail.com was the redeeming of a 10 BTC MtGox code generated from Zhou Tong's account.
* Charlie indicated that Erik Vorhees (a well known member of this community) has emails he exchanged with Zhou using the email address stevejobs807@gmail.com.

At this time, it appears that there is an overwhelming amount of evidence linking Zhou Tong personally to the Bitcoinica account hack at MtGox. Our legal department has advised us to freeze the funds for the exchange order mentioned above until further investigation by the authorities and/or legal proceedings are concluded.

Both Charlie and Mark have informed the current Bitcoinica owners of the situation and advised to start legal proceedings as soon as possible.

Posts corroborating this information from both MtGox and BitInstant will follow. I am technically on vacation until mid august with limited internet access, however, I will attempt to answer any questions the community might have as often as possible. Please understand that some information will not be released until all legal proceedings have been concluded.

Australian Bitcoin Exchange CoinJar Gets A$500,000 in Venture Funding

http://www.coindesk.com/australia-bitcoin-exchange-coinjar-venture-funding/

Quote
Melbourne, Australia-based startup CoinJar announced it will receive “Australia’s first major bitcoin investment”, signing a deal with local venture capital firm Blackbird Ventures to the tune of A$500,000 (US$455,000). The money will come from a group of individual investors with years of technology and startup experience.

CoinJar, founded in February 2013 by local entrepreneurs Asher Tan and Ryan Zhou, is a bitcoin buy/sell exchange and online wallet service with a clean and simple interface that allows customers to link certain bank accounts for direct transfers in and out of the system. It has also developed an iPhone app available internationally and CoinJar Checkout, a payment processing system for merchants with daily transfers from bitcoin to local fiat currency.

It's very hard to say without subscribing to your website and sending coins, how much exactly I get from you for 1 coin in AUD at any given time.

All sites that buy coins in AU basically say it on the first page, like $1234 + 5% and do not require any subscription, you just fill in your bank details, get a quote - before sending coins - and then send coins if you're happy.

Your service for selling coins seem to be very unclear and unnecessarily complicated.

It's very hard to say without subscribing to your website and sending coins, how much exactly I get from you for 1 coin in AUD at any given time.

All sites that buy coins in AU basically say it on the first page, like $1234 + 5% and do not require any subscription, you just fill in your bank details, get a quote - before sending coins - and then send coins if you're happy.

Your service for selling coins seem to be very unclear and unnecessarily complicated.

so those other sites did not collect AML or KYC documents?

Not for selling for sure, I've never bought coins in my life so can only talk about selling, you can google "sell bitcoin Australia" and see for yourself, normally it's just one page where as I said you first get a quote for the desired amount, then fill in your email and Australian bank details, that's it. I'm no expert but I believe they operate legally and some of them do it for a long time, so demanding anything more than that simple interface seems unreasonable.

To get the current spot price I just go to coinjar and click "Filler" at the top - that takes you to the spot prices. You have to sign up to get a quote - I dont think you have to send coins to get a quote, but Im not 100% sure on that point.

To see this, do you need to send coins to them first?

Also, can you please tell me what is that bank account verification procedure?

To buy BTC, I had to provide photo ID and proof of address (well first few purchases I didn't, but they have changed policy: http://blog.coinjar.io/2013/08/19/identification-requirements-deposit-limits/ ).

Also, for withdrawing, they have this blog article: http://blog.coinjar.io/2013/11/25/selling-and-withdrawing-with-coinjar/

You just need to sign-up to get prices, no need to deposit. They want you to buy, so need to see prices before you can buy.

CoinJar Filler is just an app for CoinJar. When you sell Bitcoin, you are not authorising a payment directly in your wallet, so you need to give CoinJar Filler authority to take Bitcoin out of your CoinJar. We obviously own both services so this is just a matter of explicit consent.

You won't be charged anything if you don't place a sell order.

This phrase describes what CoinJar Filler can technically do by the establishment of the billing agreement. We won't do that.

If you replace "CoinJar Filler" with "SomeRandomApp", the same phrase should make sense to you. It's like giving out your credit card number to a merchant, who can really take money from you "at any time".

I've used Coinjar before once, and everything went as advertised.
But this second time I am having problems with my deposit at the bank not coming through (filler still doesn't show the money in my account).
As I have used their printout NAB deposit slip, there can be no mistake on my part.
24 hours later - no money, coinjar isn't replying to emails or tickets raised at their site.
Not happy.
Will go elsewhere next time.
Buyer beware coinjar, definitely.

Have used them many times never let me down - if the operator that entered your deposit got a digit wrong etc on the reference number it will have to manually be processed and takes time

So, did your money come through eventually?  I would have hoped after a posting such as yours, you would have at least had the decency to come back and either confirm they stole your money, or that it eventually came through.

I think this is the issue, coinjar is again without a bank to work with.
Ive no doubt your BTC deposit and withdrawals are working but it looks like the powers that be are not finished fucking around with bitcoin businesses.

edit: seems still have some BTC etc there, I'll fire off a $100 withdrawal now and report if it doesnt come through in the usual time.

Hi Bitcointalk,

I'm Ryan Zhou (aka zhoutong). I recently joined a Melbourne-based Bitcoin startup with two other co-founders Asher (Australian economist and business writer) and Jerrold (Enterprise software engineer with 10 years of experience). I think it's great to give bitcointalk forum members a quick update and overview about what we are doing and how we are improving the Bitcoin economy.

CoinJar: https://coinjar.io/

"CoinJar is a Melbourne-based startup bridging the divide between digital currency and the dollars in your wallet. Bitcoin was naturally the best place to start, being the world's leading digital currency. Founded in 2013, we quickly caught the eye of early start-up investor AngelCube who have generously provided us seed funding and mentorship."

Currently we offer three Bitcoin services:

CoinJar

CoinJar is a hosted Bitcoin wallet ("hosted" means "store just enough for transactional purposes and NEVER use it for savings") that integrates well with other parts of the platform. To be honest, there's nothing too much we can innovate on Bitcoin hosted wallets because they are so simple. However, we aim to deliver the best possible user experience. Aside from the web, we are also building an iPhone app for CoinJar wallet with great mobile experience (finally).

Please note that CoinJar wallet is a full-reserve platform with automated sweep to cold storage and we will never use customer funds for our business expenses. That said, be aware with any hosted wallet service. We recommend against our users to use CoinJar for Bitcoin savings. Always use cold storage!

CoinJar Checkout

CoinJar Checkout is the best Bitcoin merchant solution. We provide a PayPal-compatible API (in addition to our standard RESTful API) to help any online merchant to integrate. On top of that, industry-standard features: 1% fee, daily settlement in local currency (Australia only for now) and exchange rate guaranteed for 15 minutes.

CoinJar Filler

This is our killer app. Most other Australian Bitcoin buying sites charge excessive fees (usually 8-10%) and we really HATE to see that. A high fee will severely limit adoption and result in bad consumer confidence. Even though Australia has a well-developed financial system, when it comes to anything related retail foreign exchange services, it's a straight-up nightmare (even major banks in Australia all charge ridiculous ~4% spread each side for AUD/USD TT rate). As a full-service Bitcoin startup, we have sufficient liquidity available from our merchant solution and arrangements with institutional forex brokers (who give us wholesale rates), we want to pass on the savings to consumers by charging a just 2% flat fee.

Both Checkout and Filler are Australia-only for now, but we are definitely interested in expanding overseas. (Contact us at info@coinjar.io if you're interested in partnerships. Please reference this post when you contact us.)

We also have a by-product:

Melbourne Bitcoin Euthusiasts meetup! (http://www.meetup.com/Melbourne-Bitcoin/)

I attended yesterday's first meet-up session with 17 other Bitcoiners. It was really a great event and CoinJar plans to do it approximately every two months. So please join the meetup group if you're located in Melbourne!

Let me know if you have any feedback with our service offerings. Feel free to comment in the forum post.

We are in the process of setting up a company bitcointalk account.

this is become a competitor of bitcoins
but you fix the system, until it's same as bitcoin system
thanks

Anyone know/can explain how coinjar workout their buy price?

Its always been around the actual market price. But the market price for the last 24 hours has been $475-$478 or so and coinjar price has been $488-$490. Then they add their fee on top of that.

Seems like double dipping. Has there been an announced change in their pricing?

Thanks

Post by: perlboy on September 30, 2014, 03:54:41 PM
Hi coinjar & Co,

Firstly, congratulations on launching a service which many in Australia will no doubt use. I do have one question though, you specify there's only 2% on the current spot price. For Australian customers does this include the GST element of 10%? If it does and given that once your revenue exceeds $75K you would be required to charge GST how is charging 2% on current spot price sustainable?

Thanks,

Stuart

Without a specific ruling from the ATO, we consider Bitcoin input-taxed supply, just like shares, bonds, derivatives, foreign currencies and precious metals. That means you have to pay GST for goods and services when you make purchases using Bitcoin.

The 2% fee itself already includes GST, because we charge 2% for the service we provide, and we will absorb it for now. (We may increase the fee to 2.2% if our profit is affected by GST, but there's no immediate plan.) Currently for CoinJar Checkout merchants, we give them access to a paper trail of GST paid, so they can easily claim GST credits if they are eligible.

(We are still in the process of GST registration, but the registration will be backdated to our incorporation date.)

Ok, and further to this since you're targeting the use of a tax ruling associated with financial services and intend to onsell them to end users (essentially acting a currency exchange) does this mean coinjar has an Australian Financial Services license and conversely is coinjar registered with AUSTRAC to ensure money laundering regulations are adhered to?

Stuart

And, we come back to this and link it with this: https://blog.coinjar.com/2014/09/30/how-the-new-ato-guidance-affects-coinjar-users/

I wonder what the ATO will think about prior GST collections.. Hopefully Coinjar will get an exception on past transactions.

Good luck cause Mr. ATO isn't someone you want to annoy.

Thanks,

Stuart

I recently joined Coinjar and their support team are great though they recently made a change to their verification system, I used Austpost ID when I joined.  Now they want a JoP to verify my I’d documents and send them into them.

The problem is they want to hold your money for a minimum of 7days to deter fraudsters from using their exchange. However they never sent out any notification this would be happening and I have been locked out of the market for a week nearly and been unable to buy alt coin.

I also notice their BTC price is delayed or different from current market by a few hundred dollars.
