how can sell bitcoin in my country ?
Why is everyone complicating you ? its very simple....
Go to websites like localbitcoins.com or paxful.com and simply make an offer for whatever offer you want to be repaid.
The secret about decentralization is that nobody will be able to control this when you are connected to the rest of the world! you can easily sell your coins for western union or bank transfers, etc...
Now if your government track you and catch you, that's a different story.
do like me and load your house with guns and grenades

good day
