Hmm, I wonder if these markets could possibly stay irrational for longer than I can stay solvent..

Would be interesting if all the major exchanges suddenly required verification for coin withdraws.

Bitcoin Withdrawal
You are not allowed to withdraw bitcoins at the moment.

Could there have been some major hack attempt involving a bunch of accounts that they have now temporarily frozen?

I only have .25 BTC on there and no 2FA. They are displaying the coin withdraw form normally for me.

EDIT: Based in europe

So we have at least two users who cannot withdraw reporting that they received some spamscam e-mail supposedly from btcguild in the last few days. Could we be on to something?

Fact: BTCGuild gives a statement about fake mails sent from their adress to emails belonging to BitStamp-Users
BitStamp freezes some Accounts, independet of 2FA.

Some people use a separate e-mail address for every account, would be nice to hear if anybody like this also received the btcguild spam.

I did receive that E-mail as well, I just read the email and was like "yes nice try", so I guess that was it.

I wonder how stamp knows which accounts received that e-mail, assuming that is the withdraw suspension trigger.

I guess then that we had a leak at bitstamp side.

We need to hear from somebody who used an exclusive address for their bitstamp account (ie. one that they have not used on some other service), yet still received that spam, to know this for sure.

I use 2 exclusive IP addresses, and use 2FA and use all their security features, and I got my BTC withdrawals blocked, so I really do not know what happened exactly, I guess their announcement will answer everything

Sorry for not being clear, I was referring to an exclusive e-mail adress above. This would tell us if stamp leaked the e-mail addresses.

Amazed by the amount of people saying they don't use 2FA.

Seriously guys, WTF? How difficult is to download Google Auth on your phone and to set up the 2FA on your exchange account?

Why do you try so hard to be the low-hanging fruit and thus to be hacked?

WHY???

I guess i'm not the only one who worries about losing the phone and doesn't really know how to keep backups of the 2FA stuff properly.

you just write the key down on a paper and save it, do you lose important documents as well ?

Yeah well, silly me thought I had to upload my keys to google or some shit to have them stored away from the phone. I'll give it a new try, thanks!

That's a good point. May I suggest a solution?

Set up 2FA. You'll get a barcode that you scan with your phone to set it up on there.

But now don't click it away, but prt scrn, and PRINT that barcode on a piece of paper. Hide it somewhere that you deem safe. Maybe your wallet? Or maybe inside your copy of "2000 novel recipes made purely from Matzen"? Something like that.

If you ever lose the phone, or need to re-setup 2FA, get that printout, and scan it.

What turned me off the google auth stuff at first was lots of people reporting that they had printscreened their OCR code and then they had their accounts emptied soon afterwards. This made the whole thing seem to tricky to use for the moment.

I guess there are maybe even alternative 2FA clients one can use? This is going off-topic so I'm off to do some research. Thanks to you two!

bitcoinbuilder could still be trading goxcoins, 1goxcoin = 1.2 BTC, like the old times

When and if they restore withdrawals it should trade 1:1, yes?

This is fucking insane, i have a negative balance and even if i sell every goxbtc i have i will still be in the negative. Nice scamming Josh.

But maybe you were accidentally credited with more BTC than you deposited some how.  Like Fluidjax said, can you go through the transaction log and pin point where the mistake occurred?  If you lost BTC, either the accounting won't add up, or they'd need to fudge losing trades that you didn't make, right?

Omg, plz dont tell me builder was operating fractionally as well lol

I do not think it is scam. Just pure incompetence.

Agreed, Josh seems like an okay and probably legit guy, but the site is just a mess. I dont see why i should face coin loses just because they fucked up technically.

otoh, you used purchasing power you were not supposed to have. a bit like spending money from your bank account that was mistakenly credited. you are responsible for your own trading.

You dont seems to get that it was not the case, oh well w/e

Ah sorry, got the impression you lost on a position large enough to take you negative. Anyway, adding up the transaction log should bring some clarity, check with josh if your's is corrupted for some reason. I just checked my tx log on builder and it looks fine, I used the one from My Account -> Download full account history.

Hope you get it sorted.

The bank has to suffer some loss too. Its their mistake in the first place.

sorry lol, if you mistakenly receive some money and spend them / lose them, you are still responsible for the loss. maybe bank will be unable to recover and have to eat it, but you cannot seriously be proposing that gambling away money credited in error is somebody elses reponsibility??

So the bank goes scot free for its error? In my book the bank has to pay a fine too.

In the situation at hand it seems bitcoinbuilder is simply washing its hands off and the entire liability is on Magicmexican.


I guess it depends on the error, if the order were never entered on the account ofc the exchange should eat the loss. But if its a question of losing track of sizes and prices then its down to the trader i'd say. The tx log will tell all once it's been tallied.

Problem is, i was not trading with anything "extra", all my trades in the past days were correct. But today when i logged in my acc, my balance was fucked up, i had more goxcoins than i had(not a ton more, just more), plus a pretty big negative "real btc" balance, and then Josh said that "the only way to get rid of it is to either deposit more real btc or sell goxbtc" - but even by selling 100% of my goxbtc i would still be in the negative, so i sent him another email, pressing the issue and saying that this is a fucking joke. And only after that email he took a part of my goxbtc to get rid of the negative balance. (Which i also did not like, because it looked like he was trying to put everything on me to see how i would react first)

I am still doing some calculations, but i think i ended up paying for their technical fuck up anyway. So thats that.

Sounds messed up, tally up the logs any way you can asap. You need to know how builder arrives at their numbers.

Can we safely assume by now that Billy was Marks favorit pet, let loose on the exchange trading infinite funds.

Now please tell me, how well would you trade with infinite funds? I sense a game concept taking shape Smiley

Bitfinex is notorious for this. This is why I don't trade with Stop Losses. I have seen the high spike on Bitfinex practically match my stop loss before trending back down and never revisiting the price point since. Ended up being robbed out of what would have been a rather decent short trade. That was my last short for a few week until I got in at $626 just before crash.

Stop losses do that when you place them at the same spot as everyone else. Try exploiting these stop cascades by strategically placed limit orders just beyond where all the stops are. That way you will enter with edge every time. When I started doing this I realized the stop cascade points where actually where the trends turn, you will mostly be on the right side doing this. And since you get in with edge, you can mostly scratch the other times.

I don't know if Mark is a bad person, in fact I dont think so, I think the fact that he covered this up and tried to solve it without telling anyone was brave, but sadly this was the worst decision, he should come clean right away and minimize the damage....

Its wasn't brave, it was an attempt at the easy way out.

a bankruptcy is the easiest way out, trying to pay people back because of your fuck up and cover it and live with that nightmare everyday is not that easy, you have to have some real balls, I for sure cant do it.

Obviously a payback is a strong move, indicating character. A delaying cover-up while hoping for recovery and still taking in new money are all hallmarks of a coward out of his depth, or worse.

The only way to get money in or out of the exchanges is in CNY throught Chinese banks. Any profits the Chinese traders may make are in CNY and come out of the pockets of other Chiense traders.  That is true even for traders who do arbitrage between China and the rest of the world. 

there is CNY trading on ripple, are they not able to get out this way?

Ok, decision made. When I get back home in a month and get to my good computer with decent internet, I'm going to start to do some trading also. Until now I have just bought and hold and tried to do my learning and now I feel I should be able to do it. Made some imaginary calls "now I sell" "now I buy" for awhile now and it seems more likely that I can make more btc than lose some in the long run. Let's see how it goes.

Start with tiny money and work yourself up, pretty much everyone is simply trading money for experience for quite some time.

Definitely, especially when you think of all the unpaid man hours at the beginning of Bitcoin were from men at high levels of ability and would command a decent hourly rate.

Hard to see how they could have spent their time/money any better.

You still can use 4x margin so even if it is not true, you can make 10k wall with 2.5k btc.

Nothing wrong with that -- could end with massive short squeeze. Tongue

Only those who were grandfathered in can do 4x. Some get 2.5x, new users get 2x. You'd have to be insane to full leverage at 4x in this market....

I had 4X available on only one of my accounts. This changed to 2.5x recently. Exactly how is the account max leverage decided now? Will it change unexpectedly again? Is there some official word on all these changes? Pre-announcement of all such changes (here + @bfx + optional e-mail) would be very good, especially when it comes to micro structure / engine patching and changes in the actual trading contract specification. These should be published several weeks in advance unless there is emergency requirements. Also, maybe you could push changes to some fixed weekly "maintenance window".

In the 4 months I've been with BFX there's been at least three major changes to their margin trading facilities, each time my first indication that something is up has been trades not closing or error reports piling up.

First they dropped the leverage, then they came for order entry flexibility (changed it to work more like a cash market) then they hit short duration traders with fee increases (this segment should already bring in significant fees, and contain most of the mm / statarb activity, which arguably provides quite a bit of value to BFX and its users. (any secret tobin supporters at the BFX offices ?? Smiley

Due to my lousy scripting faculties/attention span I failed to notice something amiss until the losses had piled up. Turns out all my closing orders for the last 2 days were rejected due to unsufficient funds (opening was fine. go figure...). Before this I was attempting to exit by transacting -1.01 x current_position. The quick fix was to change this to 0.99X, microstep across zero and then opening up to full size.

While it was arguably on to me to fix proper reporting / cross-checking etc to start with, a simple e-mail detailing the execution logic changes would have gone a long way. I can only imagine how it would feel to someone with a more sizable account.

And to top it all off they then changed the swaps so short duration trades would cost a minimum of a full hour of interest. Changing interest calculation rate to 1/second (and/or) an option to disable auto-close of swaps would fix this.

The order entry issues could be improved on by using some liquidity-adjusted margining measure, as then you would need real money to effect real change.

Anyway, i heart BFX and trust them like i trust the stamp. I just want them to be even better (and plz give me my leverage back, i'm mostly hedged elsewhere anyway, free my bitcoins!)

EDIT: note to self, check which thread before posting next time. thought this was the bfx thread, oy well. good day to you all!

Apparently arbitragers have their own "exchange rate" that has been more or less fixed at ~6.10 since Jan/15.
Who knows, perhaps there is only one arbitrage algorithm working between China and the West, with the exchange rate "6.10" hard-coded, and the owner did not notice that it has changed.  Cheesy

Doubtful the guy would not notice someone arbing his coins away Smiley

I don't  see how he would notice the error.  Say, his robot would buy some coins at Huobi for less than 6100 CNY and sell them at Bitstamp for more than 1000 USD; that way he would make more proft than he thought, but his robot would miss some opportunities: buying at 6180 would still be profitable but the robot would not think so.  Or, conversely, the robot buys at slightly less than 1000 at Bitstamp and sells for slightly more than 6100 at Huobi; then he is actually losing money, but will only notice if/when he tries to withdraw any excess CNY at Huobi and exchange them for USD at the banks --- which he doesn't have to, since he can rebalance the two accounts by moving bitcoins, at the artificial rate of 6.10 CNY/USD that he himself established.

Note that once the coins are sold, he will not know or care about what happens to them; even if they are bought by another arbitrage robot who sells them back at the other exchange.  (Trading fees will probably prevent a runaway loop there.)

So, on the balance, I think his buggy robot would just miss some opportunities, which a competitor could exploit; but he may never notice that. 

Yeah, this makes sense. But I don't see how he could rebalance the accounts by moving bitcoin. Fiat will accumulate where the coin price is higher, converting it back to bitcoin would erase the profit and bring the operation back to break-even, no?
