  * home_addresses.txt
  * trades_summary.txt

  * mtgox_balances containing the balances of all user wallets
  * trades.zip containing monthly csv files of all trades within mtgox & coinlab between 2011-04 to 2013-11
  * trades csvs have fields:  
  Trade_Id	Date	User_Id	User	User_Id_Hash	 
  Japan	Type	Currency  Bitcoins	Money	
  Money_Rate	Money_JPY	
  Money_Fee	Money_Fee_Rate	Money_Fee_JPY	 
  Bitcoin_Fee	Bitcoin_Fee_JPY	User_Country	User_State

From this data you could reconstruct every trade within the site, and identify the address from transaction values.

This dataset could lead to loss of anonymity to a significant number of people in the cryptocurrency world.
