Are you not considering to enter bigger exchanges with bigger volume? That will definitely help the coin for sure.
That is a goal that all developers want, but now continuing to develop and gather community is the best thing before starting it all. If the community built is strong enough, there is no need for a bigger exchange to witness the success of the coin.
