the next exchange we should be listed on should definitely one of the bigger ones like hitbtc, binance etc. but for this to happen i think DeepOnion need to attract more potential investors. our overall trading volume is currently too low so big exchanegs wouldnt be able to make much money from a DO listing. But that is a topic that will be relevant in 2-3 months only
Big exchanges are likely to list DeepOnion when most or all of the coins will be already distributed. They don't like to list coins who are still in the hand of the devs in high quantities. We will probably have to wait a bit more for those. But... who knows!
