Bitcoin Heists

List of Bitcoin Heists

Following is the result of research on prior Bitcoin-related thefts. I have provided dates and times as I know them. The list is designed to be as accurate and informative as possible, and most of it is well-referenced. For disputed thefts, I have applied best judgement and included the ones that were most publicly accepted.

Because of the volatile nature of Bitcoin’s exchange price, I have denominated heist estimates in BTC. Although not heists per se, major permanent bitcoin-denominated losses are also included in this list. If I missed any major thefts, heists, or losses, or if you have any other information to contribute to one of these events, please leave a reply in this thread.

Additionally, I would be grateful if contributors write commentary for each theft. Ideally, the theft descriptions should be as detailed as possible. Much of the present commentary is inadequate.

The author of this list believes all information contained thereof to be factual; however, the author takes no responsibility for any losses associated with factual inaccuracies in the list.

Factual Inaccuracies

Although I make every attempt to ensure information in the list is well-cited and factual, there is always the possibility of error (whether on my part or on my source’s part). If you find a factual inaccuracy, please report it. You will be credited appropriately for such reports.


Donations are appreciated and are accepted at bitcoin 1MLSW1nmYkHqaHWNNkHSAHct6exd8fYYLX .

Alternatively, consider a donation to a charitable cause. Many victims of these thefts accept donations, and they likely need the donations more than I.


Without properly-defined bounds, this list could not possibly be complete. Consequently, several clauses below limit the scope of the list.


Generally, a major heist, theft, hack, scam, or loss must cause damage greater than or equal to 1000 BTC, in BTC damage only, to qualify for inclusion in this list. Thefts related to Bitcoin but with most damage in another currency do not qualify, unless customers were damaged in BTC. Borderline thefts may qualify if reasonable estimates are over or equal to 1000 BTC. Thefts that do not strictly qualify but are of significant importance are listed in the thefts not included section.

Managing Bitcoin prices

It is well-known that Bitcoin prices are volatile. Before 2011, the value of a single BTC was extremely low. Consequently, this list ignores most events that occurred before 2011. If a theft, hack, scam, or loss caused damage greater than or equal to 5000 BTC before 2011 (i.e., in 2009 or 2010), it is not listed on the severity charts. If a theft, hack, scam, or loss caused damage less than 5000 BTC before 2011, it is not listed on this list at all.

This list also employs USD cutoff values. Thefts with USD damages below the given cutoff for the year will still be included, but will be excluded from or unranked in severity lists.

Cutoff values so far are below:
YearCutoff ValueSeverity list cutoff

2009 – 5000 BTC (*N/A)

2010 – 5000 BTC (*N/A)

2011 – 1000 BTC (12000 $)

2012 – 1000 BTC (12000 $)

2013 – 1000 BTC (12000 $)

* These thefts are not listed in the BTC-denominated severity chart.

Included borderline thefts

Finally, another clause is provided to allow important thefts not meeting the cutoff to remain included. Borderline thefts, which have less than 1000 BTC in total damages, may still be included if their total damage when measured in June 2013 BTC exceeds 500 BTC. This measurement is based on Mt. Gox price data prior to 2013-06-09, Bitstamp price data after 2013-06-10, and US CPI data published by the United States Bureau of Labor Statistics.


For ease of navigation, I have assigned each theft a name. Note that this name is neither official nor permanent and is used solely for ease of navigation. To search for the heading that details the actual theft, simply use your browser’s Find function and search for the name. This will either bring you to the theft itself, or a link to the theft. If the latter, simply click the link to be directed to the theft.

Some links will appear in commentary and in lists. These can be clicked; their destination is set to the beginning of the linked incident’s section.

List of events by severity

Dear reader,

This thread has been superseded by a newer thread due to character size restrictions. A copy is left here for archival purposes; however, this copy is significantly out-of-date.

NB: This section is under construction.
In this section, each theft is listed alongside the value stolen when converted to a June 2013 BTC equivalent. This represents the true value stolen and is generally the best list in that regard. No incidents need be left out of this list, thanks to its method of ranking based on true severity.
