Go to your local chicken-trader and say "I give you two chickens." He'll say "K for what?" And you'll be like "Well....there is one thing" and he'll be like "Say no more" and give you a huge bucket of bitcoins. Then you can bash them against your computer monitor until they're in your mtgox account and you can buy whatever you want with them!

Hope that helps

On a serious note tho, Cameroon is a den of thieves. If you're an honest, hard-working human being I recommend gathering up whatever decent people you have that are close to you and getting far the fuck away from there. It's a grade A shithole, no offense.
