I just saw that you want to pay for the exchange as soon as 10 MN left for the presale. I think you should take into account other exchanges like crex24 or even cryptopia if you can.
Crex24 is a decent exchange but I don't think its the right fit for GLPM right now. The dev actually sent in a request to Cryptopia but I don't believe he has heard back from them yet. I believe he is trying to get a better deal for a listing but if not then it will either be Coinexchange or CryptoBridge. There are just 23 masternodes left for sale so we are getting closer to a exchange listing, we must all remember that right now is a difficult time trying to sell nodes while the market is taking a beating but hopefully it will start to recover soon and we can get back on track.
