Because listing on exchanges is not a project's goal. The goal is to create a working product.
That might be, but for me this is pure business.
There are enough other projects showing equal functionality. Getting this onto an exchange should be #1 prio. right now.
I hope after distribution of ETH based tokens the team will make this possible to make it list on big exchanges. I hope it will be on binance for sure because it's big project.
