VPNCoin has potential, but I don't think it'd go past $2. And even a $2 price would mean a profit of 200 times for investors, which sounds and is insane.
If I were to choose a coin that would go up that much in a short time, it would mean that I have to choose the next scamcoin. 1000% positive change would mean too much. We have seen this happening to most coins: they go up very very fast, and then they suddenly stop for a few hours, days or weeks and then it falls. Look at Bitcoin in 2013, Dash a few weeks ago and Ripple last night. I prefer a slow but stable growth like Bitcoin or Monero instead.
Ripple will likely get pumped soon. The whales came in last night and played with the currency, and it turned out into a panic mode for many investors.
