For me:
Centra Card = WCX.
I cant belive, how many people are naive here. Simpl, incredible. Good luck to all of you, who invest in this "invisible exchange".
How long has their whitepaper page been a 404 error?
Um its not, i just tried it. I know alot of people still think this is a scam, but to allow Alpha/Beta testers in whichever it is, that means they will have to reorganize the site so things will probably go offline for a bit. If everyone would just relax for a couple hours we will know soon enough
EDIT: I just realized by "Thier" you meant centra card not WCX, but ill leave my post here anyway because people just need to chill out for a bit and see what happens.
