I don't think it's way too hard for a token or coin to be added at an exchange, most of the exchanges (not all) nowadays are all about money like yobit which will add your token eventually provided that you have money to pay them. Why not pay from the funds you collected during the sale to add this token in some "more decent" exchanges?
I think it isn't longer about exchange but it is about trust.
If people didn't trust a project then a trade will never happen.
It's time for MDN to build trust again to keep the project alive.
