is it possible that if my country's government still prohibits bitcoin to make transactions directly because bitcoin has not been inaugurated as the currency that applies in my country
Of course. There is no way that they can completely prevent you from doing crypto transactions. The only thing you need is a pc and internet connection and viola. I mean they can make it harder with banning exchanges and services so you can't make withdrawals from ATMs but all that is manageable. You just go to a neighbor country, withdraw money and take it home.
