Possibly. But for me, EU doesn't make any significant effect on bitcoin. We already know that they are against bitcoin, so with that said, its not the reason why the price did go down a few days ago, maybe investors just cashing it out. But its sad to hear if EU will do such a thing. I think its borderline controlling those who have bitcoin as their investments.

And I'm not sure how this can be a effective tool to curb bitcoin users. On the contrary, this may attract a lot of Europeans to seek what bitcoin is and its gonna be a headache for EU government to track all of them.
