What you look for in an exchange?
Don't list a shitcoin, list only those major coins that has serious developers.
Have you any ideas on how we can make this successful?
Have you ever heard of robinhood? They have millions of users already because of they have been known from other services (stocks) but now they are ready to jump to cryptocurrency. What's good with their service is they offer free charge.
Edit: Sorry I've realised I may have posted this in the wrong board!
IMHO, you're in the right board.
