I think there are a lot of people that invest in NXT and just leave it on a centralized exchange.  I am guilty of this. The problem is they do not visit the NXT forum or try out the decentralized NXT asset exchange. You have to actually use the service and stay up to date on the progress taking place in the NXT community (which is quite a lot to keep up with ). Piece of mind comes with having my funds on a decentralized exhchange that actually works...and works fast.
