I agree that it is important to check how much the project follows the roadmap, what has already been done and how quickly the project is developing. Now there are many exchanges and it is very important to offer such products and tools that competitors do not have.
Since not all projects follow the roadmap, not all projects publish roadmaps now. According to the roadmap, the exchange should be launched in August.
The most important thing for any project is the trust of investors. People should be sure that the project fulfills all its obligations and continues to develop as planned.
