I'm posting this friendly warning as a bank employee. We recently received a memo and report from our countries financial institute to report anyone that receives more than €1000 linked to Bitcoin transactions. The report states that 84 accounts in our country have been flagged, and from these 84 flags 52 are under surveillance / investigation. I am not sure if this is connected to the Darknet, but I am quite sure that no vendor wants to have their business investigated. Before this report we where only required to report deposits above €10500 within a year. So them moving it down all the way to €1k is quite troubling in my eyes. I cannot tell you which country this is, but the report attached comes from Europol...so I am assuming it is EU wide. Do what this information what you want.
I have found a earlier report from our financial institute available in PDF form on Google. It is in Dutch but I am sure it will provide enough proof: https://www.fiu-nederland.nl/sites/www.fiu-nederland.nl/files/documenten/jaaroverzicht_2014.pdf The release of this report is 21 May 2015. The report starts at "Monitoren van encrypted currencies: bitcoins". Which explains how people are being monitored for Bitcoin transactions and how it has led to a bust.
Sorry for my bad English. But I thought I do my part in warning people.
