Rapport TRACFIN 2011 (Traitement du renseignement et action contre les circuits financier clandestins)
Basically TRACFIN is a commission dealing with AML.
First, for a good laugh, let me translate the introduction to bitcoin (p21) :
Bitcoin is a virtual currency, which may be qualified as "viral" (bitcoins duplicate automatically)
What is more intriguing is the example case they talk about : Illegal activity as a banker using a virtual currency
with no legal value not being a legal tender (p23).
TRACFIN attention was drawn in June 2011 by company A activity. This company is used as an intermediary inside euro area for bitcoin trading by the company B, located in the country X. [...]
During a period of 3 months, more than 3000 transactions have been recorded for amount around 2.4M€ in deposits, and 1M€ in withdraws. The deposits (corresponding to bitcoin buying) could be up to 30k€ per transaction, and some people could to several transactions on the same day
From the date and the amounts, looks a lot like MtGox, when they still had their account in France. They don't have it anymore, but I don't recall hearing about them being accused of "Illegal activity as a banker using a virtual currency with no legal value." (exercice illégal de la profession de banquier avec une monnaie virtuelle n’ayant pas cours légal)
