One of my favorite exchange is Binance due to high volume of this.
The tokens listed here are good and well filtered. it will need to go a long way before having a new token to be listed.
P.S
I have accounts in many exchanges due to i can't choose where i will sell my bounty tokens. only the team can decide.
Team also listen to the investors before they list their coin on the exchanges. Bounty rewards are dumped,so teams know what they are doing. If the bounty hunters don't respect the team's decision and they run to sell the bounty allocated tokens to the first available buy market order, I don't think the big exchanges will accept such coins as an approved project.
