This makes me get the idea that the feds don't like Bitcoin and wouldn't want to see Bitcoin succeed in the US as it was meant to according to the creator.
There was never a time when the US government said they liked bitcoin; in fact, they hated it from the beginning, so this shouldn't be something new, but this attack is on those services that offer support for bitcoin.
Since they can't control Bitcoin's self, they want to control the way people make use of it 's self they want to control the way people make use of the reasons why they are going after those services that offer crypto currency to be transmitted, either to come and follow the due regulation process or to leave the US market.
