First, you should be updated with Bitcoin news and aware of its volatile situation. You know that it is not an easy job to make an exchange you should be kept in mind different factors like KYC, and securities. You took a great initiative. There are several Bitcoin exchanges even we didn't remember all the names of exchanges. Do hard work and promote your exchange on different platforms. It is a tough job but keep it on & Cheer Up!! 
It would be awesome to have a decentralized exchange coded of our own and set x amount of fee per trade to an address which can further be used to promote that exchange, in this case there won't be any problem for the users to initiate an exchange as the funds won't be deposited on the centralized server so there won't be any fear of a hack, also no KYC will be required because we won't be processing any funds the code or decentralized exchange will be acting as a mediator between 2 parties taking a small percentage of fee. So this is a win win situation.I know a lot of decentralized exchanges are out there but also are the centralized ones, so it will be better to go for innovation rather than following the herd.
