How to identify high-quality projects in the primary market?
1. The team background of the project,.whether the founding team members have other technical or operational backgrounds related to the blockchain icon project. You can learn about it through official white papers, official websites, communities, and other channels.
2. The investment institution of the project is extremely important. A good project seed will attract the participation of well-known institutions in the circle.
3. The technological innovation of the project, or a simple analogy of similar application projects.
If primary market means big markets, i think it can be considered as good project. Good not means high quality btw. Because usually some exchanges already have requirements for a project to listed in their sites although sometimes still need voting about it. For me, i am not really deep into coin especially new projects, if not old big coins usually i will only do short or mid term investment.
