World mostly tier 1 and 2 countries have start to accept bitcoin payment via micro payments.
Now the main thing what if government oppose to bitcoin ?
Firstly Altcoin is decentralized digital currency as no one control it. In major countries mostly government take control over currency, but bitcoin has change past and gives revolution to world's economy.
And government with poor economy will not allow bitcoin as currency due to political issue.
But it is future and it takes time to sustain it as well as accept it.
Every Government is oppose to bitcoin but the only thing they can do is only ban it but people are still using it.
