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.
