Hello, i'm kind of new into crypto currency, I am currently trading on few exchanges. But i noticed all of the exchanges use bitcoin to deposit and withdraw, also no matter what coin you trade use bitcoins. So when you decide to withdraw your bitcoin and convert to USD, how do you go it? I don't see any option in any exchange, which is very weird.
In my country, our governement approved 2 companies as exchange operator. I can easily withdraw my bitcoins in atm machines because there is bitcoin wallets that suitable and applicable for the people in my country.
