EtherDelta exchange has a healthy amount of volume. We are listed there
https://etherdelta.com/#ARENA-ETH We are exploring other exchange options but we are mainly focusing on development currently.
why you just get listing in decentralized exchange only ? it's not enough volume and the price not growth until now
whether you not have enough money to pay other exchange ? at least you must get listing in centralized exchange
so that your product will fast growth and more have value
