basically its telling: the prosecutors have secured the money of the german bank account. it stays with the prosecutor until the procedure is finished. it can only be withdrawn by the owners by filing a civil lawsuit in germany.
before anyone is sueing btc24 i would recommend to first claim your money at btc 24 lawyer. if they dont react properly you can still file a lawsuit. btc 24 owner simon hausdorf/his lawyer mr röhl do not even know of exactly what is the accusation. they have not received the prosecutors files yet. it is way to early to conclude that a crime really happened. check out this thread first:
