I've worked in Port Harcourt a few years ago and while it might be true that there are lots of scams and criminality, I've also met many wonderful and right Nigerians.

I would say there are not more scams than any other under development country , being from south america I will say that Caracas or mexico city or Sao Paolo are as risky.

Of course English speakers fall victim of English speaking scams, in France they claim the same about Gabon and I suppose in Portugal is about Brazilians and Angolans... while in Spain it is about us Spanish speaking americans...

It is a matter of point of view, and to proffer a generalized opinion i think one needs to know and have been in the terrain.

I would advise to be very careful anywhere you do a peer to peer Crypto transaction.

Not just there...
