Bitcoin does not ony brings us freedom but also safety because we can use our wallet without being afraid its going to get hacked like bank accounts.
However bitcoin is not accepted by Government right. When the day Government accepts bitcoins, then all the set power currency will be bitcoin only. Usd, Euro, yen, dinar and etc... All will be hide at back of bitcoins.
Some countries have already accepted bitcoin as a currency. These government even encourage its people to use Bitcoin in order to make Bitcoin more popular. However, some others do not agree with the idea using bitcoin in daily needs or even allow its people to use bitcoin. I think Bitcoin will need many years until it become a world currency
I dont know any country that has accepted or encourage people to use bitcoin, i do know some companies are trying to expose and allow bitcoin community to use their bitcoins alongs the services, that in general are the buy/sell bitcoins.
