in my opinion government slowly will welcome for bitcoin as one of their economy base.
Why do you think that?
The government is currently addicted to monetary expansion/money printing/debt creation. Bitcoin doesn't allow for any monetary expansion at all, so why would the government welcome something that will end the game that they play today?
The government has the option to stop printing money right now, and can't seem to take that option willingly.
They think that because it is better to use a internet money than fiat money. Because you dont need a raw material so you can create a fiat money you dont have to buy it. But in the internet money you only need to do is to have a advance computer so that you can mine and this will help to avoid crime. If you think that in the internet money can hack or scam, they do a system or a security to avoid that.
