Government is still afraid in bitcoin because the bitcoin can kill the currency of one's nations that's why the government start to war against bitcoin and they planning to ban it in their country, they want bitcoin to post pay taxes on them because they don't earn money in bitcoin. Government will still fight it until the bitcoin end but it is a head fight for a government.
I totally agree your opinion as you can see in this whole time bitcoin went up and down but the main it was only UP ; even if government will announce public that bitcoin is a bubble or a scam the bitcoin will be temporary affected not permanently ! . If something goes bad or good bitcoin has only way to go UP!!!!!
