Here is the internal exchanger, but not the exchange. Thus, there will be no market supply and demand. If make a exchange, then a license, a lot of work of other specialists this is a big full-fledged separate project.
Nothing prevents the team from running after the internal exchanger and ordinary if there is a desire among investors.
I do not understand why you can not combine the development of an advertising application and an exchanger? Just people in the team with special knowledge should be more and money is enough.
For the creation of the exchanger can be taken not this year to pay more attention to the platform. But in a year you can easily get your own exchanger. Then the project will receive more profit, and tokens in the price will rise well.
