I'm holding a bit too. If the team can deliver what is stated in the roadmap, its going to carve out a nice part of the crypto sphere. The Verge community is very active.
I'm in exactly the same position, only makes up around 2% of my stack but happy just to hold and see where it goes. At the very least it is ambitious and has a dedicated community, which gives it a better chance than many of the other coins around the same market cap.
