Two the most important spheres where devs should take more effort are project development itself and advertisements..
I also think that the project developers should increase the aggressive advertising of their project. Competitors do not sleep. To compete you need a very good marketing strategy.
I believe that Advertising and Marketing are priorities in the development of projects. Especially for young and little-known projects. People learn about the coin and start using it. But if the coin itself doesn't advertise that it is necessary to nobody except its creators...
