I don't believe that it is trusted...most people know how untrustworthy FB is and use it anyway (guilty). I'm not an active user now but have invested so much into it already, like the picture albums shared over the years - which for me is nostalgic of my youth. I'd have to spend a week downloading all the pictures and recording them to a timeline in the same way.  Probably the best possible move I could and should make to be honest.

As far as a cryptocurrency organized by FB, I do not and will not trust it.
