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.
The economy of the country is posing to cause some security issues and people are beginning to do dubious things for survival therefore on a normal everyone needs to priotise their security especially when dealing with things that involves money, it was a very sad story indeed and I see no reason why the victim decides to take such risk based on high selling rate, if only he had traded online with a good vendor that's trustworthy I believe such incident won't have occurred. Well, sometimes things like that are bound to occur for people to take precautions and I believe everyone who heard such story and was willing to risk it too would retrace their steps and take precautions, life is even more precious than money to we don't have to risk it at any cost therefore everyone should disregard physical trading and focus on trading online with a good vendor for security reasons.
