Government donot like what they can't control, is same with other countries especially those in the EU, not only them most countries don't just like it  .
Anything that can be use in place of currency will definitely be used for ilegal stuffs like terrrorism , Bitcoin can e en be traced easily but people can still find a way around it.. so I'm tired when a government comes out to make all these shitty  claims despite knowing the biggest fund of all these stuffs ...
