Interesting post. But if this was a pump and dump, where exactly was the 'dump'? I don't see it on any of the exchanges that have XVG listed. If anything, I see a sharp, brief, move down, followed by an immediate recovery. To me, and I could very well be wrong, this should lead to new highs shortly. I'm seriously considering ADDING to my position, but have other coins I would like to own to diversify.
Just wait for it. The recovery you are seeing is because of advanced hyping tactics. The dump should come soon. It will probably disguise itself in bitcoin's upward movement.
Why would you want to buy more of a coin anyway just because it isn't being dumped? Just look at the fundamentals. It's a coin that offers "advanced privacy" and promises "more improvements." Heard that before from like 1000 other altcoins. Nothing really to give it much value. All speculation.
