I think our government knows about bitcoin because there are some banks here now accepting bitcoin and they are connect bitcoin to them meaning the government approved it.
No government did not know Bitcoin in the last year. Bitcoin created a hot trend through its growth rate, it became one of the popularity subjects to discuss in Economy and Financial programs. I remember in the last year, when I wake up and turn on my computer, I just saw the news about cryptocurrency in anywhere. So, do you think the government not know crypto? Never!
