I wouldn't worry too much. Of course they need to crack down on any thing that enabled these evil people to do what they do. The regulations they pass may make bitcoin less anonymous (but let's face it, it's not completely anonymous to begin with) at fiat to BTC exchange points. The EU laws may resemble something like the US know your customer laws.

Perhaps this helps drive the price lower in the near term, but the currency isn't going away.

If anything this should motivate all of us to share the positives of the currency with our circle of friends and family.
