Governments from different countries up until now is still against Bitcoin for there is still lack of knowledge and understanding on their part on how things are going after using Bitcoin. We cannot say how long and when will be the time that those government politicians can fully understand everything about Bitcoin and why people are pushing it through to make it legal because of the perks associated on using this kind of currency. Maybe now they are still against it for some reason but maybe tomorrow or the next upcoming days, weeks, months or even years, we cannot say but there is a possibility that government will understand the nature of Bitcoin and realize its importance and usage.
Actually i think a lot of politicians are at place where they are not able to publicly express their support and endorse cryptocurrencies because of a fear of alienating people within their own party many of whom are staunchly opposed to cryptocurrencies or perhaps because the general public as whole still is not educated enough about bitcoin and thinks of it as that thing for criminals.
I think this is also one of the reasons or factor affecting why we only know few of those politicians who support Bitcoin and other cryptocurrencies because of such feel that they might feel unwanted that is indeed because not all people are still understanding and having prior knowledge about Bitcoin as a whole.
