Good artist copy. Great artists...

But honestly, I don´t quite see FB adding its own currency. I mean if they would do this and there currency would be dumped that could have some troubling consequences for them.

Like Steem with SBD, they would need to back their currency with some service, as without there would not be a need for a currency on Facebook.

But I guess these guys are more experienced in economics then I am, so they will find something clever.
