The complete trade history of every MtGox customer up to 30.11.2013 was leaked in 2014, you can find your own trade records in the leak. However, the leaked trade records didn't contain emails/names that you can search for, so you need other details to discover what your userID is. This page may be helpful: https://bitcoin.tax/mtgox

If you registered at MTGox before mid-2011 you can use the user database leak from around then to find your userID, which you can then use to search the trade records.

I did a quick look, and balance info appears to be available through 2014-02-25, if the 'stamp' field in the mtgox_balances file is to be trusted.

I wasn't sure if I had a balance myself so I just went through this.

Download this file WARNING FILE CONTAINS VIRUS, DO NOT RUN EXECUTABLES INSIDE ZIP. To be safe, extract the files inside MtGox2014Leak.zip\backoffice\Exports __ONLY__: https://archive.org/details/MtGox2014Leak

The exports folder contains 2 zip files, one contains a list of transactions in csv format, the other contains the output of a sql query displaying all balances.

Go into your e-mail records and find any transaction id, it will look like a v1 UUID (example: 682b3d0a-67d7-4b62-8ed4-4e1d39d54a69)

Look for it inside the btc_xfer_report.csv. The UUID before it on the same line is your wallet.

Look for your wallet UUID inside the mtgox_balances file. If it's not there you either didn't have a wallet at the time of the dump, or your balance was 0.

At least for some time, on mtgox.com you could log in with your original credentials and check your balance to make a claim. Not sure how that's going to be handled now.

I had money in mtgox. I tried checking for proof of claim a few months ago and their website was broken.

Same here. I have no way to find out how much I lost, so I can't claim :(

The MtGox database was hacked and leaked in 2014, including balance info. It's available here:

https://archive.org/details/MtGox2014Leak

DO NOT USE THE EXECUTABLE IN /backoffice/Bin/TibanneBackOffice.zip - IT IS MALWARE

Unzip /backoffice/Exports/mtgox_balances.zip.

Your user ID is a UUID, and can be obtained from your Mt.Gox account creation email, from the account confirmation link (example, sanitized)

ht_ps://mtgox.com/signup/validate?ID=1111aaaa-bbbb-cccc-dddd-eeeeeeffffff&Code=1234567890123456

Search or grep for this UUID in the unzipped mtgox_balances file and you should have values for BTC and your primary currency. Divide these values by 100000000 to get actual amounts.

The 'stamp' column appears to be a timestamp of last update of these values, and the last date in this leak with significant activity is 2014-02-25.

It's a little absurd a leak itself is infected with malware and malicious intent. The current state of Bitcoin and cryto is litterally filled with pirates and thives. I've personally been burnt for a decent amount and I am very tech savvy. Can you imagine your parents trying to navigate the cryto environment?

Yep. Not viable for people like that unless and until an exchange has the same protections and guarantees they expect from a traditional bank.

Amazing! I found my purchase and the exact amount of BTC I was holding. It's not massive but feels great to get some closure on this.
