I saw a similar thread in the games and round section and I'm wondering if they are the same contest on this one is exclusively for Naija? Pardon me if I missed that.
No, they aren't the same contest. The other bitcoin price prediction thread in the games and rounds section is open to everyone who wants to participate, while this one is specifically for Nigerians who wish to participate.
Although, both thread looks similar, but there are a few difference in the prize reward. Up to two lucky winners will be rewarded in the games and rounds section, whereas only one lucky winner will be rewarded in this contest specifically created for Nigerians.
