>[0]: (Actually it is stricter now - borderline hilarious as my bank for the last twn years starts asking for my passport because of the KYC rules)
That's an issue, isn't it? Everyone can easily be in violation.
Anyways yes if you are working with the criminals that's one thing. Running a BTC exchange, if you aren't inquiring about the customers funds (you shouldn't, it's none of your business!) then it should be no issue. If you somehow know the BTC was stolen from Mt Gox, then yeah, you're helping with the hack and should be charged for that (not for money laundering, just for whatever the general charge is as a participant to a crime).
At the bottom of it the regulations create an objective standard for when you "should have known" the provenance of money, so it seems fairer to have them than not.
