maybe the government doesn't understand bitcoin, as in my country it's still not permitted / banned on bicoin, but many have played bitcoin in my country, except in some parts the government doesn't know what bitcoin is, and I'm sure sooner or later they will know what it's bitcoin. and immediately permitted
It is not because the government doesn't understand bitcoin 
the government doesn't want to understand and just want to kill bitcoin> Bitcoin is threatening to the existence of bank, that is the reason why the government hate bitcoin.
