You mean to sell bitcoins from person to person face to face ? Isnt that risky ? You will never know if the person that you are dealing is a criminal and what if they will beat you up upfront after sending them the coins ? I think its better if we can only sell our bitcoins online and nowadays there are now alot of service , some are from wallets/exchanges and they allow multiple cash out options without the need of banks .
An example would be very helpful!
