its good question, how people can trust on new website.
because its too early exchange, what i suggest to the customers to start from very small amount, see if all ok, if really all going good then people can start trade with high amount.
my website lauched to air just today. people can start to trade.
i belive that every exchange get the started in this way.
That men's,you are the owner of this site. No one believe your site,There are many high reputated site where people can easily trade their coin and trust those site mostly. Trustiness is the first fact of site.
However,if you want promote your site,than open a signatures campaign in this forum.And prove that you really a trusted man and wanted to publish a new trading site.Hope you will success. Best of luck for your project.
