I could remember a sad story that was shared in the forum about a guy who was attacked during a physical trade and I believe that should serve as enough lesson for use not to accept such option as it's never a good option and shouldn't be even tried.

You self supposed know say nobody wey get enough sense go gree trade such physical trade even though say the rate too good except say na person you know already offline.

Imagine saying you want trade a $1000 dollar to naira with the current price na very big risk to carry such money self dey waka for both the vendor and the seller.
