Why Many Country's Government think Bitcoin is a Illegal?

[Doctor]

Bitcoin is a coin which is Precious more than Lord Of The Rings  But I don't know why many county's governments prohibiting Bitcoin and they think it's illegal. Even in our country If I say something openly about Bitcoin then Police will catch me! WTF! What do you think about it?

I think the main reason is the government cannot  controll bitcoin over. They are afraid.

I think it makes sense that the government doesn't endorse bitcoin because they fear fiat will be abandoned, and people prefer bitcoin as a place to store wealth and investment. the government has difficulty controlling bitcoin, so the government will have difficulty getting tax from bitcoin.

That's because of many reason like fear of lessen their income from corrupt activities, some is simply they just still don't understand, and some are simply just want to create their own. But this all reason can't stand for the perfect  time when the demand is unstoppable.
