They should its the future, I bet they make their own coin.

The Facecoin?

As I have learnt FB is already having Facebook credits, which is equivalent to centralized pre-mined alt coin.

this makes a lot more sense then the face coin as you know that fb credits cannot be 51%ed

Yes, because fb credits are 100% controlled/owned by the FB.

The basic difference is that that is not de-centralized and hence does not depend on cryptography.

Yes, what I am trying to say is that FB credits are not de-centralised and are not cryptocurrency.
