does anyone know why vtc is so strong
Yes. Because this guy did a video on it saying he's been researching coins for weeks and decided Vert was the only one he'd invest in. Then the video got an airing on BrotherJohnF's "Bitcoin Channel". Within 25 hours of it appearing, the price started rising. (Unjustifiably).
Now that that video's fading into history, it will start to dump again and you'll be able to get some.
