Scammers are from every damn countries in this world, I know nigeria is full of scammers too but don't go around trusting projects because their members aren't from Nigeria lol, I'm kinda reluctant on russian blockchain projects too hahaha, it's a pity there is no way to safeguard crypto space because of decentralization.
Yes every country have a scammer every part of the world have it.
It is easier for them now since we could easily connect to everyone through the internet,
So we should be careful on who we would trust and on where we would invest.
But we couldn't say that the project is a scam because they have a Nigerian on their team who knows maybe he/she is good on that choosen field.
