Physical exchange aren't advisable because they're not safe, they would prevent you from been scammed but also exposed your info to authorities and other government officials that needs your information. This exchange has to be registered and the government could be tracking transaction going on over there to prevent money launderers from making used of the exchange to wash their dirty money .

Your safety is not also guaranteed as you could be tracked back to your apartment and those who were monitoring you could do harm to you to steal your money from you hand. Physical exchange doesn't provide privacy which is needed. Physical exchange are like banks which I hate.
