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?
Everyone could really be possibly a quality trader but the hard thing on this initial phase on how you would able to drive traders to such exchange and trade off a particular coin.
There are lots of criterias to considered first before making any trading activity.
1. Popularity of the Exchange
2. Trust
3. Volume of the coin
4. Fees
For luring in potential traders then you should set a competition just like on other traditional projects when it do list out on exchangers.
I agree with you and may I add with number 5. Great customer support "ease of transaction dealing with exchange". Being fast to respond on problems with deposit and withdrawals is a plus for an exchange, if they resolve uickly. I prioritize with big volume turn out also being processed or traded as it may equates to many trader and popular also. Fees is also another thing.
