I have that feeling to...it is time to spread to other exchanges...it is becoming increasingly dangerous to hold your tokens and cryptos anywhere on the exchanges
They are taking lot of time to list in the exchanges other than Etherdelta. I think many people are awaiting for the higher exchange to get more reputation about the coin because the value might increase if they list in other exchange.
Maybe etherdelta will be the only one.
I think maybe in january-february 2018 when the alpha version will be release, the teams will consider to add PPP in another exchange. Because this project i think very interesting, so impossible if they don't have any plan to add PPP to other exchange
