Cross posting for a noob who doesn't have access

Quote
as some of you may have noticed from watching the charts at:

http://s2.bitcoinity.org/markets/bitcoin24/EUR
http://bitcoincharts.com/markets/btc24EUR_trades.html

there is still trading activity occurring on bitcoin-24.com, despite the site ostensibly being closed for the past ~12hours.

it is actually still entirely possible to access the exchange interface in full and make trades as normal (at least in EUR, haven't tried USD). not sure of API access as i've never used it.

withdrawing funds may also be possible but i'm not certain of that.

hopefully this information is of some use to btc24 users - not entirely sure how but i can't keep it quiet - hence signing up to post this

can prove this if necessary.

 Grin i imagine the police to confiscate the hardware... this would mean the police stores the stuff in some basement forever because they dont know how to handle anything related to IT.

Exactly. And if that happens people would probably never get their money.

Simon Hausdorfs Bitcoin Wallets:

Cold Storage:

Balance: 8,848.39013303

Semi Hot Wallet (maybe Cold storage):
1AnixjBYxpTzAmfSa8kRdBiUaSGV2e9d26 > https://blockchain.info/address/1AnixjBYxpTzAmfSa8kRdBiUaSGV2e9d26
Balance: 7,100.77857022

Hot Wallet:

Balance: 0

Affiliated Wallets, probably his own, since all the affiliated addresses send each other coins:

1MVCn7PuFtnCgHKjYvVpqE62ifVKNCA8mU > https://blockchain.info/address/1MVCn7PuFtnCgHKjYvVpqE62ifVKNCA8mU
Balance: 1,532.00
Received BTC from 1Anix as well as 1AfY


Makes a total of 18079 BTC in control of Simon Hausdorf, and thats what I found in about 5 Minutes work. If we search deeper, we might find more. I found some edgy 96.xxxxBTC transfers from 1Anix but I am not sure if they are his because some of them are spend. But its unusual he sends money from 1Anix, since this is his cold storage(or maybe not).

Feel free to contribute.

No need to real worry until those balances start to shrink or disappear without anyone receiving their money back. Since fast withdraw is essential to a scammer, I don't think Simon is planning to scam us or all the money would be long gone. Of course, if people start calling the police too soon, that can trigger some undesirable consequences. Simon knows it's hard to run anywhere in modern European Union or even abroad. No need to remember him that. And he already updated his message on https://bitcoin-24.com/. At least the "closed your Bank account in Poland" was changed. But he should prepare things in order to allow people to withdraw their bitcoins. Or, at least, write a more assuring message about he returning all the money and give us some kind of deadline.

on an exchange that is effectively live though? while his customers still have active orders, no less.

i think someone has just worked out how to access the exchange and is taking advantage of the glitch to inflate their balance. you can see that orders are regularly executed twice, giving double coins/EUR, which you can then trade the opposite way in multiple tiny orders and have many of those executed twice too. end result = free money essentially. i tried it briefly few hours ago and increased my EUR balance by 200 in about 5 mins... stopped straight away of course (and am ready/willing to hand the funds back)

trading engine is an absolute joke atm - this is why i didn't want to share how to get in

But from where comes the opposite for your trade? do you need to do "crosstrade", trade with yourself? You dont trade/match with other orders from other market participants, right?
From where comes the money (200 eur) you earned?

I like to understand the leak.

Thanks

nowhere - it doesn't really exist other than in bitcoin24's database. for whatever reason, the trading engine is spazzing out and crediting twice (or more) for trades in some instances. it doesn't matter how i'm buying from or selling to really, because the amount of free coins being made out of thin air by the bug makes it impossible to lose.

i tested this last night when i was the only one on it (seemingly). i don't mind detailing this now because the site is properly down and no-one can get in to take advantage, but if i'd revealed how as soon as i knew this could have been happening for hours. from memory i did:

make buy order 1 btc @ ~80 euro
make buy order 1 btc @ ~80 euro
account is credited for 3 btc, only 160 euro taken

make sell order 0.1 btc @ ~77 euro
x30

account is credited for 4.5btc worth of trades @ 77euro/btc

so i ended up with approximately +200EUR more than when i started over the course of a few minutes and just some quick clicking. really i should have been down about 6EUR i guess.

i was clicking very rapidly when making the buy/sell orders in order to reproduce the glitches i'd read about and it obviously worked very well. however even when NOT trying to induce a problem the glitch would still occur - i made a small trade just so i could see if the BTC withdrawal function was working, and ended up getting credited two or three times. just a simple, one click buy order, with no load on the engine as i was just about the only person there. something is clearly very wrong. i wasn't on the exchange this time yesterday but i can see why it was taken offline so abruptly if this was happening. it also explains why the hotwallet is being kept empty - if everyone draws out their coins this can't be corrected. if the coins stay in the system, the database of trades can be rolled back (as i understand it) and BTC/EUR/USD balances can be restored to something resembling 'normality' before the glitch.

if anyone is to lose out it should be bitcoin24 as they will (morally at least(!)) have to settle their customers' accounts whilst also taking the hit of whatever bitcoins were wrongly credited by the trading engine and quickly extracted. the admin hasn't disappeared just yet (posted on reddit earlier) so i haven't lost all hope.

Thinking about it, the most annoying thing about this is that it prevented me from buying at yesterdays low. Today the price is almost double... bah, that would have been a nice profit margin! Boo. Anyway, hopefully it will be back up tomorrow Smiley
