KevinMatiru I would suggest you open a cryptonator account , Then invest in bitcoin mining from the daily bitcoin you get you can diversify and change from bitcoin to other currency . All in your cryptonator account .
isam45 Buying try localbitcoins.com, remitano.com. You can also become a merchant there i.e buying low and selling high to gain profit margins. For cloud mining try hashflare.io, mining genesis. For trading try bitfinex, cex.io, and the likes
Metrd Please be weary of these crypto currency mining companies its a really big risk. I really hope you're doing your research about it.
