There are so many different rules in different countries, sometimes even BTC is banned, yet there are still BTC transactions in these countries. How does it work? Is it easy to sell btc in your country, or to buy something with it? What have you bought, for example? Or what are you planning to buy?
Everything happens a little differently, you can easily exchange bitcoin for cash in offline exchangers and this is how you can do it. There are some organizations that are ready to accept payment in bitcoin, but more often it is USDT, but this is rare and it is easier to exchange bitcoin in exchangers and buy what you need for cash, this is the easiest way. I think until laws are passed that will regulate crypto, then this will remain difficult.
