An close associate in the US got a call from his bank and was informed that they will have to close his account due to his bitcoin transactions... this was under the premise that he did not have a money transfer certificate (like Western Union).
I was curious if anyone else has had a similar experience... the concern is if banks are starting to collude against virtual currencies in the states.
I've heard of others losing their accounts due to the same thing. I contacted a local bank and asked if they would do the same, and they said that they just won't accept Bitcoin, and that using exchanges (to convert fiat <-> BTC) is fine as long as they are sending ACHs. I've gotten similar answers from a few other banks as well.
