But they should know that bitcoin is the future currency, and we see how many countries are now accepting bitcoin. For long even the government disliked the idea of decentralisation, but I guess they have shifted their mind set today and want to embrace it.
Bitcoin is the future; we are already in that future, Governments don't like decentralisation and privacy, and still they don't like it even till now. You might see governments buying and accumulating bitcoin, but that does not mean that they embrace it for its decentralised features but because of the financial gain they want from the market; they have seen how profitable it is to hold bitcoin for the long term, and they also want to benefit from it.
