If you haven't heard of CEX yet you are already late! It is the best way to invest your Bitcoins currently into GHS (GigaHash per second). The best way to mine bitcoins, I've already tripled my original 2 bitcoins! You pool together with other people and the profits can even be pre calculated! CEX is also an exchange, While your Gigahash is mining for you, you can also sell it higher to immediate profit in bitcoins and still keep whatever it has mined for you as additional profit! This is the future of bitcoin trading/mining...DONT MISS OUT...get your gigahash ASAP and mine/trade your way to more bitcoins
