EON will be listed once the price will be live, first it will surely be in their own platform and we might see a big exchanges next.
It might be hard to get EON listed just like how WAVES were 2 years ago. They will also find EXscudo platform a huge competitor in the next years and will even beat them soon since this project have the connection to credit cards which Exscudo had in the team's roadmap.
If their own platform can generate good revenue and add more users per day,then what is the need for new exchange?
An example for this is Binance, they listed their own token and now it is being listed on other exchanges without any fee.
