Thank You! Oh yeah they are asking for 10k+ these days.
I think it is worth it. Looks even cheap.
You want to use the reputation and infrastructure of a reputable exchmage, which has no interest to support your project.
Additionally, if the exchange is good enough, you will also be listed in coinmarketcap.com, which gives a lot of credibility to your project.
I would stay away from new exchanges
As you don't have a reputation, you will have to pay. There are some projects that have support of reputable members in their team since day 1, exchanges want to list those projects in their exchanges. But that is not the case.
