BITSTAMP SERVICE TEMPORARILY SUSPENDED

We have reason to believe that one of Bitstamp’s operational wallets was compromised on January 4th, 2015.
As a security precaution against compromises Bitstamp only maintains a small fraction of customer bitcoins in online systems. Bitstamp maintains more than enough offline reserves to cover the compromised bitcoins.

IN THE MEANTIME, PLEASE DO NOT MAKE DEPOSITS TO PREVIOUSLY ISSUED BITCOIN DEPOSIT ADDRESSES. THEY CANNOT BE HONORED!

Customer deposits made prior to January 5th, 2015 9:00 UTC are fully covered by Bitstamp’s reserves. Deposits made to newly issued addresses provided after January 5th, 2015 9:00 UTC can be honored.

Bitstamp takes our security and soundness very seriously. In an excess of caution, we are suspending service as we continue to investigate. We will return to service and amend our security measures as appropriate.

lololol

Here we go again...another service bites the dust...mt gox part 2379248723897234879234. This shit will never end until it takes bitcoin down with it.  Unbelievable.

Im thinking they currently just have a technical issue, im not using them or have any money in there but its doesnt look like a gox situation.

The fact of the matter is...regardless how 'bad' this situation really is...it shows that bitcoin money is safe nowhere.  Exchanges can basically take your money and run at any instant and claim they were hacked...with no repurcussions or explicit proof.  If that isn't enough to scare away any potential future adopters, I don't know what is.

This have something to do with recent BTC price?  I'm guessing yes.

Mtgox again?  ???

January is a bad month for Bitcoin

Im thinking they currently just have a technical issue, im not using them or have any money in there but its doesnt look like a gox situation.

No, not Mtgox again. Mtgox lost all bitcoins whereas Bitstamp states cold storaged coins are fine.

So either you can't read or you don't trust Bistamp.

Bitstamp is hacked. It's a fact. I think they can cover the loss from their HUGE profit they made last year IF they want that, of course  ;)

There are rumors that their bank account is closing too.

So what is the 'huge profit' they made? Source?

Their latest filed accounts (for 2013) doesn't show P&L as they qualified as small company, but their P&L reserve was at $0.8m, impressive for a start up, but far from 'huge'.


Here's the coindesk article on the recent events:

http://www.coindesk.com/bitstamp-reports-hot-wallet-issue-tells-customers-not-deposit-bitcoin/ (http://www.coindesk.com/bitstamp-reports-hot-wallet-issue-tells-customers-not-deposit-bitcoin/)

whose is reporting the whole profit?  there is no company is this world to do that. they will pay taxes. remember, BitStamp is one of the biggest exchangers.

also, look to the amount of the transactions they had last year and look to their fees. it's pretty easy to make a summary calculation.

Yes its a real problem and it makes an advert for regulation and bitcoin banks.  We need safe simple wallets and exchanges.

Kinda of news that will make people lose trust in bitcoin security and its viability as a safe currency as a whole. When new or potential investor read this, they will have doubt about putting their money into bitcoin. Bad news indeed... I wonder amount of btc that has been compromised.  :(

I like bitcoin but believe it is dying and will be worthless. The reason is that there is ZERO security, ZERO public knowledge, ZERO advertising and ZERO good news. […] I am cashing out

I like bitcoin but believe it is dying and will be worthless. The reason is that there is ZERO security, ZERO public knowledge, ZERO advertising and ZERO good news. Combine this with Apple Pay whom basically took the btc idea and ran with it. Forget the "fiat" currency BS. The losses that the masses of btc owners have incurred over the last year would take eternity to recover. Too many scammers and with the cost of electricity and difficulty and ZERO profits, the entire attraction of btc is GONE. All the cloud miners are worthless. It's has more signs of a demise than any currency or commodity out there. I am cashing out and hitting the small cap miners.

WTH?? The ship can start sinking too fast...

Can I get your coins at ZERO cost? Thanks!

They are handling this incident good :) im happy with them still

we are talking about 14% of their coins lost ? pffff... :)
a lot of money lost. millions !

Where do you see 14% of their total coins is lost?

I think they just lost a few hundred coins max.

this sucks.

Solution: use bitcoin the way it was meant to be: without 3rd party *anything*...

It is still out.!! No idea how long it's going to take.!! this sucks.!! I personally dont think it is a similar situation to mt.gox..! but anyways they should sort it out soon.!

Thank you all for your patience, we are working diligently to restore service and hope to have an ETA later today.

Bitstamp lost 18K BTC. https://blockchain.info/address/1L2JsXHPMYuAa9ugvHGLwkdstCPUDemNCf


sell your Bitcoin. the price will go DOWN ......!!!!

I bet this is Bitstamp themselves making some tricky maneuvers.

Sooo, create a panic sell and snap up BTC when the price drops and then pay out their depositors with cheaper BTC and pocket the difference? Gee, why would anybody do a thing like that??

the source addresses and destination address are all cold wallets of Bitstamp.  The total amount of these cold wallets are about 200K.

The 18k BTC lost is about 10% of total reserve of Bitstamp.

it is NOT Bitstamp reserve. it's the CLIENT's money.

So is this the hot wallet then?: https://blockchain.info/nl/address/1Drt3c8pSdrkyjuBiwVcSSixZwQtMZ3Tew

how did you calculate this "small" balance? it's around of 5 MIL USD.

How much does have Bitstamp? 50 MIL? Let's get real. :)

Even so, Bitstamp MUST have these money in bank, right? I think most of these money came from bank deposits.

The fact of the matter is...regardless how 'bad' this situation really is...it shows that bitcoin money is safe nowhere.  Exchanges can basically take your money and run at any instant and claim they were hacked...with no repurcussions or explicit proof.  If that isn't enough to scare away any potential future adopters, I don't know what is.

Having lost various amounts at cryptorush and coinex...hearing stories like this don't even phase me...it's just another broken record that you basically expect.

Addtionally...anyone ever notice how these exchanges just so happen to conveniently go bust right when bitcoin is experiencing huge price volatility (either good or bad).  It's like the scammers don't even really care about hiding their motives anymore, because they know they can get away scotch free.

this sucks.

Very interesting address. Specially the very high fees payed for ultra fast confirmations.

it is very curious that the Bitcoin price didn't fall YET.

normally, any real "stock" market would have reacted until now. the "players" would have sold...I think Bitcoin foundation is not strange of this.

It is not true , with 1btc you have the same time/chance to receive confirm (include in a block) as 0.0004 btc . It's a question of lucky ....

If the space is limited, and i.e. we have a tx with lot of inputs/outputs (high size) then a high fee creates incentive for priority inclusion.

On bitstamp: "Customer deposits made prior to January 5th, 2015 9:00 UTC are fully covered by Bitstamp’s reserves. Deposits made to newly issued addresses provided after January 5th, 2015 9:00 UTC can be honored."

But if you look at the transactions of that possible hacked bitstamp address, the first transaction happened on January 4th, 2015 2:26:20 UTC. and the last transaction happens 2015-01-05 18:12:07, it is still accepting transactions after 9:00

Someone wasn't aware of what's going on and send to the old address maybe?

Seems to me those are the funds from the hot wallet: http://www.coindesk.com/bitstamp-claims-roughly-19000-btc-lost-hot-wallet-hack/

On another note, where did this statement come from? Was it made directly to Coindesk at CES maybe?

If they indeed lost ~ 19,000 BTC, they're seriously fucked. There's no way they have enough own reserves to cover it. And I doubt they have insurance covering such event.

They can buy 19k btc with the fiat value , it is not an impossible thing to do....  (and maybe the price will raise a little).

We are working to transfer a secure backup of the Bitstamp site onto a new safe environment and will be bringing this online in the coming days. Customers can stay informed via updates on our website, on Twitter (@Bitstamp) and through Bitstamp customer support at support@bitstamp.net."

The 19000 BTC isn't even half of the volume that was traded per day the last couple of days. It is a big hit but i suppose it is recoverable.

I'm more worried about the wording in the statement where it states:

I don't think it should take days to copy and check their environment, why would it take this long?

And updates haven't been provided since this morning on either Twitter or their website. No source for the last statement on Coindesk. I'm worried we won't hear anything for a few days now. And that reminds me of Gox...

The company has generally been respected within the bitcoin community. In May 2014 it passed a proof-of-bitcoin-reserves audit overseen by BitcoinJ developer Mike Hearn, and in June it beat other bitcoin companies to win the Europas' Best Virtual Currency Startup Award.

I don't think Bitstamp is going to disappear overnight like Mt. Gox. They've got a lot to lose.

A lesson learned from the whole Mt.Gox debacle is that they need to keep communicating. This doesn't seem to be a priority at the moment. I'm still wondering where that statement on coindesk came from. It isn't on their website or twitter. So how would customers know (apart from reading coindesk).

Having said that I don't think they'll go bust because of this. I've been using them since long before Mt.Gox started to slide and they've proven to be a reputable exchange.

January 6, 2015, 12:34am UTC: We have temporarily suspended Bitstamp services. Bitstamp customers can rest assured that their bitcoins held with us prior to temporary suspension of services on January 5th (at 9am UTC) are completely safe and will be honored in full.
On January 4th, some of Bitstamp’s operational wallets were compromised, resulting in a loss of less than 19,000 BTC. Upon learning of the breach, we immediately notified all customers that they should no longer make deposits to previously issued bitcoin deposit addresses. To repeat, customers should NOT make any deposits to previously issued bitcoin deposit addresses. As an additional security measure, we suspended our systems while we fully investigate the incident and actively engage with law enforcement officials.
This breach represents a small fraction of Bitstamp’s total bitcoin reserves, the overwhelming majority of which are held in secure offline cold storage systems. We would like to reassure all Bitstamp customers that their balances held prior to our temporary suspension of services will not be affected and will be honored in full.
We appreciate customers’ patience during this disruption of services. We are working to transfer a secure backup of the Bitstamp site onto a new safe environment and will be bringing this online in the coming days. Customers can stay informed via updates on our website, on Twitter (@Bitstamp) and through Bitstamp customer support at support@bitstamp.net.

Coindesk are as bad as mainstream media channels these days and had at least one outright BS article lately, this ones pushing ripple so wouldn't be surprised if there's FUD in there. Getting hard to get good news these days, this forums spammed by astroturfers and there's a lot of FUD on the popular news channels, especially the forex coverage. Hope when they've something to say its something good but the biggest scumbags on the planet are fighting back now so the only thing certain is coins you have the keys for.

what good news do you want? 50% fake transactions. the big exchangers are manipulating the price along with the Bitcoin Foundation, the exchangers are earning millions when the Bitcoin price is going down....this is the Bitcoin world; full of speculators and this how it will be from now on...I am not sure for how long...
there are not too many NEW fouls to "invest" :)

They can buy 19k btc with the fiat value , it is not an impossible thing to do....  (and maybe the price will raise a little).

So you are assuming they have $5million laying around of their own funds to do this?

I doubt it.

Let's assume that Bitstamp was audited by Pantera in March 2014 before they invested $10M venture capital into the company.  Considering this was done shortly after the MTGOX debacle, I think it's safe to assume anyone dropping a $10M investment into a bitcoin exchange requested a verified and substantial financial audit of the company.

If they have been running a legitimate 100%+ reserve since that investment was made, they can likely weather the storm.

So you are assuming they have $5million laying around of their own funds to do this?

I doubt it.

That, indeed, is the problem. They have to come up with $5 million to reopen.

They can't reopen without the money. If and when they allow withdrawals again, everybody is going to take their money and Bitcoins out. If they try to pull some of the stunts Gox pulled about stalling withdrawals, this thing will come unglued even faster.

Bitstamp is a UK company. UK bankruptcy laws (https://www.gov.uk/statutory-demands/overview) are much more pro-creditor than US or Japan bankruptcy laws. As soon as a company owes you money and isn't paying its debts, you can file a "statutory demand"  The company has only 21 days to pay before you get to go to court to have them forced into liquidation.

Any creditor of Bitstamp can do this. Tomorrow morning, if they want.

There's also a UK court procedure for a "money claim", for amounts up to £100,000. This is only available if you have an address in the UK. That can be done on-line. You have to send a letter demanding payment first, but you only have to wait 14 days before filing a money claim.

Don't wait. That didn't work out with Mt. Gox.

The big question is will they allow a run on Bitcoin and fiat withdraws?

Anyone who has a large sum trapped there would likely want out ASAP.

If they allow this and bite the bullet I will give them credit where it is due. Otherwise they are insolvent.

Looks like 10k BTC per day is a nice reasonable number to assume is their average daily volume traded.

Based on those numbers I do not believe they have enough to cover said losses in full. Remember now they have expenses over that year.

For most financial companies holding other people's money, losing 5-10% of assets under management pretty much guarantees insolvency. $5 million in operating cash is probably more than what a typical $1 billion hedge fund would have.

Do they have insurance?

Where are the europeans converting their BTC to fiat these days? BTC-E seems to have very big fees for wire transfer withdraw.

Time will tell.

Assuming they had a 10,000 BTC per day trading volume that turns into 40 BTC in trade fees per day...

For 1 year (365 days) that is 14600 BTC. That would be their entire yearly profit from fees.

They lost 18000+ BTC in one fell swoop.

Not sure if I would think they have enough reserves in profit even if it were 20,000 btc per day trade volume (which is way over estimating).

Or they could operate using fractional reserve method, a 90% reserve is still much much better than any banks which only have 10% of client money at hand.

Bitstamp needs $5 million within days, or they're going into bankruptcy.

Apparently they say they will resume operations in the next 24 hours:

That's not what "fractional reserve" means. For a bank, a loan is an asset - someone owes them money. Banks get into trouble  when many loans go bad, as happened when the real estate bubble popped. Or they get into trouble if they have short-term deposits and long term loans, and too many depositors want their money out at once.

That's not Bitstamp's situation. They don't own 30-year mortgages.  They have no big illiquid assets they can sell off. They have nothing except their customer balances, and, according to their financial statement filed with Companies House, a few hundred thousand in paid-in capital.

Bitstamp needs $5 million within days, or they're going into bankruptcy.

Let's see. Hope this is not another BS. Though I have a relatively small amount with them compared to other members, it feels pretty crappy.

You are overlooking old accounts, which probably make up a good portion of reserves.  For example people who deposits $10 worth of BTC, like 3 years ago and forgot the account even exists.

They could probably do a cash grab on those accounts (ie people who haven't logged in for 3 years) and make up a large amount of their losses, without anyone being the wiser.  Just locked out all those accounts, and if someone happens to try to login just give them the run around and "no record of your account"....sure it's shit; but it beats going bankrupt or giving everyone a haircut (and going bankrupt in the future).

Or claiming that everyone deposits after their January 6th warning to old addresses were "lost' even if they weren't....basically going through the couch cushions they could probably scrape together 10% of reserves.

It is the same, although banks claim that they have this and that asset, when they suddenly need money, those loans can not come back in one night or one month. In fact 90% of the deposit money are just sitting in the bank's account without moving, that is the original reason banks loan out those money to earn interest on those dead money

What those coins in bitstamp's cold storage are doing? Collecting dust. They can actually loan out those coins and operate more like a real bank, but without loaning anything out they are much safer than a traditional bank if a large scale of withdraw is happening. For normal bank, if more than 40% of customer are doing withdraw simultaneously, they will run into a liquidity crisis and go broke. But unless more than 80% of bitstamp customer withdraw from bitstamp at the same time, they will be fine (Of course I suppose that they are doing 100% reserve, if they already practice FRB then no one knows how serious the situation is)

BTW, they don't need $5 million, they only need 19000 coins, no big deal for them. But if bitcoin price suddenly rise by 10 times, they might run into problems, just like MTGOX experienced, their initial loss of 200K coins caused by 2011 hack becomes so huge amount of wealth after 2 years that they can never earn it back

Apparently they say they will resume operations in the next 24 hours:

https://www.cryptocoinsnews.com/bitstamp-resume-operations-next-24-hours/

GOX said more than once they would resume operations.

Let's see if they will honor what they say or if things will go even worse

Apparently they say they will resume operations in the next 24 hours:
https://www.cryptocoinsnews.com/bitstamp-resume-operations-next-24-hours/

Bitstamp's announcement of setting up a duplicate site in San Francisco reminds me of Mt. Gox claiming their "new trading engine" would fix their problems.  That was just an excuse for stalling.  

I don't think that they going down yet. But they have serous problems. So let's hope the best!

more than 10% of their coins in their possession stolen.

So how do they handle the instant run on bitcoin and fiat once they reopen?

Institute bullshit daily limits?

That won't fly well given their situation. I would imagine there would be a pretty big uproar among customers/users should they not allow FULL btc and fiat withdraws.

Just consider that as a long term loan to a hacker. MTGOX managed to operate 2 years before they could never make the lost coin back, but MTGOX is unlucky since they were hit by the ASIC evolution of bitcoin mining, and the bitcoin price rose by 100x because of ASIC miners

At current situation, with no large mining tech advance in horizon, bitstamp have plenty of time to make those coin back

many people forget that Bitstamp "reserve" it's the client's Bitcoin.

Pretty much this. People forget customer's money is NOT a Bitstamp asset. They have to cover up the losses from their income, which is based on trading fees.

I may add...and not only on trading fees. You cannot make millions from 0.03%. This is like free so they have other source of making money from this biz; maybe the price difference... :)

in short, 5 Millions USD are not easy to be covered from fees.

You need millions of transactions in one year just to cover .

How many transactions does have an exchanger like Bitsmap per day?

And Bitstamp's profits from selling ripples needs adding to the total. You could buy ripples directly from Bitstamp at a price they decided, which was always way above the going market price.

I may add...and not only on trading fees. You cannot make millions from 0.03%. This is like free so they have other source of making money from this biz; maybe the price difference... :)

Fees are from 0.4 to 1% at bitstamp (buyer and seller pay from 0.2-0.5%), they generate majority of the profits, check volume and you will see, so they can cover loss with that.

This is conjecture on my part, based on Bitstamp's Twitter statements, such as "Working alongside the team from San Francisco, progress towards redeployment is strong. Huge thank you to for your confidence and patience."

Bitstamp desperately needs a few million dollars right now. Where are they going to get it? They're two unknown guys in their twenties, in Slovenia, with a mail drop in London. Nobody is going to fund that. If they were in Silicon Valley, they might be able to get VC funding. They have a user base; they're fundable. That's probably the motivation for the move to San Francisco.

Whether they can get funding remains unknown. If they'd closed a deal, they would probably announce it. So it's unlikely there's a deal in place.

Stamp might be sitting on loads of unclaimed bitcoins from traders who are incarcerated or failed to submit kyc documents. However, most governments require unclaimed funds be turned over to the State. Perhaps Stamp believes it has legal standing to keep bitcoins on grounds that such laws apply to fiat funds only? Weak argument, but may buy Stamp some time.

Forfeiture of balances?

If true...then wow!

Not sure if that is legal anywhere on the planet to just take shit because they didn't get verified in a certain time frame.

From my understanding they sent out various warnings over a ~1 year period about verifying accounts. After the period was up, accounts that were unverified had to give up their identity before any transactions are processed. I guess if you refused to verify and did not withdrawal within the given time, then you would have to verify or lose you balances.

Analysis: Bitstamp Hacker Almost Stole Additional $1.75 Million

Bitstamp narrowly avoided losing an additional $1.75m in bitcoin during its recent hack, according to a blockchain analysis by an independent researcher.

In the final hours of a $5.1m heist that took place at the exchange five days ago, the $1.75m in bitcoin was quickly moved to an address thought to be used for cold storage by Bitstamp, analyst Danno Ferrin has found.
...

A lot of talk about previous profits: If the owners cashed it out in their own pocket (absolute legit), then they would think twice to throw their own money back into the exchange. If they reopen, I expect a cashout run. This will last till their reserves are empty and thats it, bankruptcy.

They've just updated their whois data to an anonymous whois protector:

Whois Record ( last updated on 2015-01-09 )


http://whois.domaintools.com/bitstamp.net

let's not forget that they reported a profit of about 800k USD in 2013....

even we double it because Bitstamp may report fake numbers in order to avoid possible taxes....it's 2 mil USD per year net profit roughly.

we can say they need 2 years to recover the loss (IF they will have the same amount of clients; clients who will run away ones the Bitstamp will open the withdrawals).

in the mean time, they have to open their pockets and hoping that everything will be as in 2014.... very hard to believe that,

Some new details on the story:
