Hi all,
I've been using BTCe leverage trading on MT4, but I noticed the data is not the same as for the normal trading in BTCe.
I wanted to do some statistical analysis of the data, but the historical data provided in the MT4 platform is very limited.
Does anyone have all the data, or at least a big chunk of it (from the beginning of the year) and can provide it?

In their site they say it usually get's credited after 3 confirmations. Now we are on 40 confirmations, several hours have passed, and nothing.

Hi.
Not to this address, but I've sent quite some BTC to my localbicoins account before.
The transaction now shows 31 confirmations and localbitcoins still didn't credited it.

Anyone having problems with Localbitcoins?
I just tried to deposit some BTC to my wallet, it already has 7 confirmations on BlockChain and nothing shows up at localbitcoins.
Worst, my wallet address changed for some motive to a very old one I had there.
Anyone had this problem before? I'm trying to send the BTC to a buyer and now I can't.

Thank you all.
I've now changed the addresses like you suggested.
So if I got it right, the lesson to take is, if anyone ever has access to a wallet backup, it's unsafe forever.

Ah, I get it. So, they can spend my coins that where already in the wallet at the time of the backup / or before I changed the password (that part I didn't get straight), but they cannot spend the new coins that arrive there.
Thank you. The old wallet was hacked actually and they took some coins :/ ... but I have a miner still sending coins there (I'm going to change it after a few blocks) and I was afraid they could also get my new stuff.
Thanks again.

Hi,
this might seem a very simple question but I can't find a straight answer to it.
Imagine someone has access to an old backup of my wallet (QT client, Multibit, Electrum, etc...) and that this person has also the original password of that wallet.
That password has changed now, but can someone move my BTC with the old data?

Hi, my account got hacked 2 days ago and the hacker took more than 4 BTC from me. I know for some of you it's a very low amount, but believe me, for me it was quite a hit.  Anyway, while trying my best to make sure my computer is protected now, I noticed a Multibit Failsafe-data folder in my Documents folder. Until now I always thought the hack had something to do with my Dropbox account and not with my laptop, but after seeing this I'm very suspicious. The date of creation is from the day of the hack, about the time I changed my wallet password. I'm sure I didn't create that folder myself, nor did I ask Multibit to create it. So - this might seem a bit paranoid, but - is this folder supposed to be there and it's something Multbit does automatically, or can this be related to some backdoor left behind by the hacker? |

I've just noticed a Multibit Failsafe-data folder in my computer.
It was created (not by me) 2 days ago after I discovered the bitcoin hack (probably about the time I changed my password, but I'm not sure).
Is this file supposed to exist or is it a suspicious activity?

I moved the wallet to Blockchain.info, it's not that I trust my gmail account (and dropbox) is completely safe now but I guess it must be impossible to enter the account after I put up the google key two factor authentication.
blockchain.info is even worse than a desktop client! You computer has been compromized. Moving to blockchain.info won't make things any better. What you should do is backup essential documents, delete everything on your computer, reinstall the operating system, install anti-malware software like anti-virus apps and scan and restore the backups. Then change your passwords everywhere including your email accounts. As far as bitcoins go you should move all the coins to a new wallet. Make sure you set a password on your new wallet. At least blockchain.info has 2FA. If he sets it up with his phone number, they would need to have his cell phone in their hands to log into the account. Not to mention it has IP lock so if you are outside if the set I.P address it wont function. And a disable TOR IP address option too. I think all this hoo-har surrounding the blockchain.info 2FA is slightly overblown for the following reason. The 2FA is only required for actions using the site. Many people back up their wallet file or have it automatically backed-up/emailed to their email by blockchain.info. THIS WALLET FILE IS ENCRYPTED (using your main password) BUT NOT BY 2FA (or blockchain.info's "second password"), which I think many people believe it is. So all an attacker needs is a copy of this backup file, and your primary password, which apaprently people keep losing. Just wanted to make that point. I suppose, if your email has a strong password, and 2FA of its own (e.g. gmail), THEN you might be starting to get to somewhere secure. OP I am interested, I think you mentioned that you are using OS X, right? Also, would you care to divulge your password metadata with us, for example for both your email, dropbox and multibit: 1) were the passwords all different? 2) length of each password? 3) alpha, numerals and symbols (#) in each password My condolences for your loss too, by the way. Thank you. Yes, I was using a Mac. 1) No, the passwords for the wallets where the same (I know, stupid me). The passwords for email and Dropbox where different. 2) About 8-10 3) The passwords for the wallets and the email where pretty good: alpha, numerals and symbols. The passwords for Dropbox was just alpha, although it was just a bunch of letters I came up with, not a dictionary word. Also I turned on 2FA everywhere and changed all the relevant passwords and disabled TOR in blockchaininfo. But I'm still apprehensive about what you said from the wallet backup from blockchaininfo. I didn't made a backup, I just printed that original wallet access codes. But now I'm a bit paranoid about if it's possible for the hacker to have access to that as well. Any thoughts on that?I think it's really difficult for the hacker to have some backdoor to my computer. It's a Mac, the SO was freshly installed about 1 month ago and it's got no fixed IP address. I still think this has something to do with Dropbox and/or my Gmail account. But to say the truth, now I'm not sure of anything anymore. |

I currently keep mine in a blockchain.info wallet as it was recommended to me a while back. I would certainly be interested to hear if there is something more desirable though.
Electrum. I could never recommend storing your bitcoins online, sorry. But the two factor authentication in blockchain.info doesn't make it more secure? Or even better any local storage that uses the two factor authentication, does it exist? |

If it really is TOR then what is the point? It could be anyone and anywhere. Really sorry but its likely gone forever.
Yeah, I kind of accept that would be the outcome. But I still feel the right thing would be to tell the police about it... even if they do nothing about the stuff :/ |

if your funds were stolen from multibit it has nothing to do with multibit.
It means your computer is compromised. Using qt OR blockchain.info
on the same computer will make you lose more money.
But my computer was not even on. What if the hacker had access to the wallet backup and the password? It wouldn't need my computer that way, right? Not he wouldn't, just to add I use armory for any large amount of coin. Electrum offline storage also works well. Ok, just one thing. Where do you keep the backups for this? I mean, I could make a linux installation in a USB pen and use it just for keeping the bitcoins. But I'm afraid that if something happened to that USB pen, my BTC would be lost forever that way. |

Ok, thank you all for the support.
I already spent most of the day changing the most important passwords I have (email, dropbox, ebay, paypla, etc...).
I had installed Maverics (Mac OSX) about 1 month ago from scratch, but well, I guess it's time to be a bit paranoid so I'll install it again like you suggest.
About the lost bitcoins, perhaps it's a silly question, but do you think it's worth to make a complaint in the police? So far the hacker didn't move them from any of the two addresses where he sent them.
The IP address the hacker used was: 79.134.234.200
I can see this belongs to some guy in Austria, but like I said, I think he's just someone how runs a TOR server.

That's so bad  How could the attacker hack a multibit wallet? A custom trojan? Well, I know the hacker had access to my email (I saw a login using the security questions in the GMAIL logs, it comes from some guy in Austria, but I think he was just running a TOR node). Now, since the wallet backup was sent by email to another person, I think that's how he got it. I don't know how he got the password tough... I have some suspicion it has something to do with Dropbox, but I can't find any logs in Dropbox to confirm this. I moved the wallet to Blockchain.info, it's not that I trust my gmail account (and dropbox) is completely safe now but I guess it must be impossible to enter the account after I put up the google key two factor authentication. |

You are wrong, Hacker did not paid huge fees. check this out :  Why would he pay high fee? Hi, I know that now, it's just that Multibit gave some 3.4 BTC fees like the screenshot I posted, but that part must have been some mistake. |

Thanks it's kind of a shitty situation since I was keeping this money to pay the faculty fees.
It was my fault tough, I should have used something with a two factor authentication :/ I think it's best if I keep my BTC in a blockchain.info wallet from now on, or something similar if you are able to suggest a good alternative.

I had more accounts hacked, although this was the main one. I guess since they took from the others they understood that I would see it happened and they change the security settings for this account.
