When big exchanges?
Big exchanges will come after the end of the airdrops probably. The dev was in contact with some of them but they don´t want to add a coin that is at airdrop stage.
Anyway, Cryptopia and Kucoin are working very good. I think we will see the Onions listed in some big exchanges in the Q2 of 2018.We're setting things in motion now for bigger exchanges. As noted, this will be a lot easier once the airdrop is over (alleviates the impact of dumping from the Devs - we all know that won't happen, but the exchanges have rules to that effect) and will mean that there is a larger circulating supply.
I know that the devs and you moderators won't dump. We're already more than half way on the airdrop and soon DeepOnion will take off. With what I'm saying now, both Cryptopia and Kucoin are working great. The price going up as well as the trading volume on both sites.
