I would like to point out that gold is also a one-world currency, currently accepted in more locations worldwide that bitcoin. But that doesn't mean that gold is going to be the NWO's preferred one-world currency. Like others have stated, their currency will be a fiat money that they control and issue from their world central bank.
Ok I just want to point out I dont believe in the NWO crap however ...
Say there is a group that is smart enough, powerful enough, and influential enough to do the things people claim they do. Are you telling me they are not smart enough to to be able to create a digital currency that everyone would use? And not only that, but make you believe it was your idea in the first place, and that its completely safe from such control. Because if it were me, average joe, that's exactly what I would do. And im not any of those things listed above.
If such a group of people existed, they would be smart enough to realize a single fiat currency isnt a sustainable option if everyone is against it in the first place. Much less whole nations that cant even get fiat right. What already more interconnected internationally than the internet and P2P?
