I mean my BTC address. We all know that BTC transactions are public viewable, so i don't want the buyer to see all transactions i made before with other people.
Localbitcoins is the best choice. In my country you can sell bitcoins for e-cheque. You get special code, you go to any ATM, enter the code and withdraw money without inserting any card (you don't need to have bank account), so only footprint you leave is your face recorded by ATM camera and your IP and nickname on Localbitcoins
In my country is much easier, you don't have to get money transmitter license, you simply register a company and you can start making money selling bitcoins on LB
