For those who do not understand the OP, Bet9ja is a top, prolly the number one gambling/betting website in Nigeria, where you can place bets on varieties of stuffs, especially football and other virtual games.
Now to the point, OP i really do not understand what you mean by your thread and its purpose, Bet9ja and Bitcoin are two different things, and in case you do not know, betting isn't peculiar to Nigerians, it happens in pretty much every country in the world where it is legal, one can also invest in Bitcoin and still place as much bets as they want. Finally there are also a lot of crypto/Bitcoin betting websites, just take a look at majority of signature campaigns in the forum and you'll understand, so Bitcoin is also used to play bets, so it's a win-win situation for the 'two parties'.
Finally, there is a local Nigerian thread, here is it, you can move it there as i don't think this belongs to B&H
