Why government dont kill btc? because they cant.

Protecting? Its hard to believe yet this is fully contrary when it comes to centralizations.

Owning secretly? Of course they do have lots specially to those coins that had been confiscated on illegal sites just like what happened into those Silk road funds recently.

You know government where they do dive in opportunities which do seem that they might be fully against with it but who knows that they
do have some plans behind.
