There is a Korean exchange whose airdrop campaigns MemberPass is working on. I think they have a great model with transaction fee mining. I believe this type of exchanges will be around.
My question is where do the quality traders hang out? What motivates you to join a new exchange?
For me the motivation is what security has the exchange got to provide for my little funds in the custody of the exchange. Secondly, I like an exchange that provides me an ease of navigation on its platform. Also, an exchange with high trading volume is a catch for me. I don't want to endorse any particular one but you can peruse exchanges on coinmarketcap.com to see who has what.
